Understanding how our brain perceives space

European scientists looked into the cellular properties of neurons responsible for space coordination. Insight into the neuronal network of the entorhinal cortex will help understand what determines space and movement perception, and also how it is linked to brain-related disorders.

The ability to find one’s way is performed in a special site of the mammalian cortex known as the entorhinal cortex. Information regarding place, direction and destination is processed in specialised neurons called grid cells. These cells present with specific spatially firing fields that repeat at regular intervals and have been found to scale up progressively along the dorsal-ventral axis.

Further dissection of this neural map was the subject of the EU-funded project ‘Spatial representation in the entorhinal neural circuit’ (Entorhinal Circuits). More specifically, scientists hypothesised that the topographic expansion of grid cells paralleled changes in cellular properties and particularly in the current (Ih) which went through hyperpolarisation-activated cyclic nucleotide-gated (HCN) channels.

Using transgenic animals with forebrain-specific knockout of the transmembrane protein HCN1, researchers found that HCN1 modulated grid cell properties, especially the size and spacing of the grid fields. This clearly indicated that HCN1 was crucial for the spatial representation in the entorhinal circuit. It also implies that during self-motion–based navigation, the current that goes through HCN1 is responsible for transforming movement signals to spatial firing fields.

Entorhinal Circuits results offered unique insights into some of the fundamental principles of neuronal assembly and microcircuit operation in the mammalian cortex. The generated knowledge will hopefully shed light into the role of the entorhinal cortex in various neuronal diseases like Alzheimer’s and schizophrenia.

Water Therapy

Water Therapy To Cleanse And Release Toxins From Your Body

Water therapy or hydrotherapy supports free and safe treatment. The treatment is done without the help of any specialist.

This therapy is used when you require perfect medicine to cure all sicknesses.

Drink six glasses (1.5 liters) of water everyday and avoid taking medicine, tablets, injections, diagnosis and other treatments. 

Process of water therapy treatment:

Hydrotherapy is a very simple treatment. Everyday you have to take 1.5 liters of water. If water is not clean, then it is required to use clean and boiled water for doing this process.

Drink 1.5 liters altogether, after drinking you should not take any food or liquids for at least one hour. If you feel difficulty in taking 1.5 liters at a time, then take water gradually (give a gap of 2 minutes after drinking 4 glasses of water).

These 1.5 liters of water will help in cleansing your body. If you follow this process regularly, the toxins are released through sweat or urinal excretions. You should not take any alcohol last night.

Benefits with water therapy:

With water therapy, you can prevent and cure some of the diseases. If you drink water sufficiently, then it will help in enhancing your glow of skin and keep you physically fit. Water therapy is used in regulating the temperature of your body.

If you consume water properly then you can be free from constipation. Acidity can be cured with only two sessions.

With hydrotherapy, diabetes can be cured with seven sessions, hypertension can be controlled in four weeks, pulmonary TB can be cured in three months and some cancers can also be controlled.

Drinking Water therapy helpful for treating following diseases:

If you suffer from following diseases, follow drinking water therapy. It is alternate natural treatment, so it will not cause any side effects.

Anemia, rheumatism, general paralysis, obesity, arthritis, sinusitis, tachycardia, giddiness, cough, leukemia, asthma, bronchitis, meningitis, kidney stones, hyper acidity, dysentery, gastroenteritis, uterus cancer, rectal piodapse, hostorthobics, eye diseases, ophthalmic hemorrhage, irregular menstruation, breast cancer, laryngitis, headache, urogenital diseases are the diseases that can be cured from this therapy.

Properties of water helpful in some of the following conditions:

The physical properties of water are used as back pain therapy and other musculoskeletal injuries.

Buoyancy of water will help the patient to support weight and will improve balance and strength.

The viscosity of water provides resistance by its gentle friction. It will help in strengthening and conditioning of an injury and reduces the risk of injury due to loss of balance.

Hydrostatic pressure of water has powerful effects to improve heart and lung function. This pressure is useful for maintaining and strengthening heart and lung function. This pressure will effect in improving muscle blood flow.

Water therapy is the natural alternative treatment that can be followed by any person at any age of your life time. Water without life is impossible and you can live longer with water. The treatment with water is very simple and you can follow water therapy at your own place.

FIVE TRICKS TO MAKING IT AS AN ENTREPRENEUR

5 Things to Un-Learn From School

You spent a lot of time getting an education. But if you want to make it as an entrepreneur, it’s time to forget some of what you learned.

You spent a lot of years in school. You learned a lot.

Some of what you learned you need to un-learn as soon as possible. Here are five key attitudes you should adopt instead:

1. If you only do what you’re told, you’ll excel.

I know. School was hard.

But not that hard.

If you did what you were told–go to class, do the reading, turn in assignments on time, etc.–you could get As. Initiative was not required and, in fact, was often frowned on.

Now–whether you work for someone else or run your own business–doing what you’re told makes you average. Not superior, not excellent… just average.

To be above average, or to achieve better than average results, you must do two things:

1. Do what others are willing to do, and do it better, and
2. Do what others aren’t willing to do

Otherwise, you’re just average.

2. Being micro-managed is to be expected.

Sure, you felt overly-controlled in school: Dates, timelines, rules… not to mention the seemingly arbitrary policies and nonsensical assignments. You saw graduation as the day you would finally have more freedom.

Nope.

In school you paid people to criticize, direct, and at times micro-manage you. Now you’re the one getting paid… yet you somehow don’t feel it’s fair that investors, partners, or customers can dictate what you do, sometimes down to the smallest detail?

Don’t expect someone to trust you to perform a task or service–and give you money to perform that service–until you’ve proven you can be trusted to perform that service.

Then, once you’ve proven your skills, if you still feel micro-managed it’s your responsibility to change the situation. Communicate before you are communicated to. Answer questions before questions are asked. Demonstrate your value before you are asked to prove your value.

No one wants to micro-manage you. They have better things to do with their time.

If you’re being micro-managed it’s probably because you need to be.

3. Your time off is the highlight of the year.

You may have forgotten your mom's birthday, but I'll bet you knew the exact day every semester ended and the start and end of Spring Break. And you lived for snow days.

So it only makes sense to see weekends and vacations as the highlight of your working year, right?

Actually, no: If you feel you endure the workweek just to get to the payoff of the weekend, you're in the wrong business. Find work you enjoy; then you won't see time off as a chance to finally do something fun but as a chance to do something else fun.

While you'll never love everything you do in your professional life, you should enjoy the majority of it.

Otherwise you're not living–you're just working.

4. Getting criticized means you failed.

Here's another pay/paid dichotomy. In college you paid professors to critique your work.

So now that you are the one getting paid, why is it unfair for someone--like a customer, investor, or key partner–to critique your work?

It's not.

When you get negative feedback, see it as an opportunity. Think, "Wow, I didn't realize I wasn't doing that right. I didn't realize I wasn't doing that as well as I could."

Criticism is a chance to learn--and this time you're getting paid to learn.

Never complain when someone pays you to learn.

5. Success is based on toeing the line.

Say you disagreed with a professor's point of view on a particular point. You may even have been right... but the only way to get an A in the class was to parrot the professor's take on the subject. Except in rare cases, confirming and following the rules was everything.

In business, conforming only ensures that you will achieve the same results as other people.

If you want to achieve different results you'll have to think and act differently. Do your homework, think critically, and don't be afraid to create your own path.

But don't be different just for the sake of being different. Be different because it's who you are and what you believe... and because it will get you where you want to go, with your integrity and your sense of self intact.

 

Working with solvents tied to cognitive problems for less-educated people

Exposure to solvents at work may be associated with reduced thinking skills later in life for those who have less than a high school education, according to a study published in the May 29, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology.

The thinking skills of people with more education were not affected, even if they had the same amount of exposure to solvents.

"People with more education may have a greater cognitive reserve that acts like a buffer allowing the brain to maintain its ability to function in spite of damage," said study author Lisa F. Berkman, PhD, of Harvard University in Cambridge, Mass. "This may be because education helps build up a dense network of connections among brain cells."

The study involved 4,134 people who worked at the French national gas and electric company. The majority of the people worked at the company for their entire career. Their lifetime exposure to four types of solvents—chlorinated solvents, petroleum solvents, benzene and non-benzene aromatic solvents—was assessed. The participants took a test of thinking skills when they were an average of 59 years old and 91 percent were retired.

A total of 58 percent of the participants had less than a high school education. Of those, 32 percent had cognitive impairment, or problems with thinking skills, compared to 16 percent of those with more education. Among the less-educated, those who were highly exposed to chlorinated and petroleum solvents were 14 percent more likely to have cognitive problems than those with no exposure. People highly exposed to benzene were 24 percent more likely to have cognitive problems, and those highly exposed to non-benzene aromatic solvents were 36 percent more likely to have cognitive problems.

"These findings suggest that efforts to improve quality and quantity of education early in life could help protect people's cognitive abilities later in life," Berkman said, who worked alongside study author Erika Sabbath, ScD. "Investment in education could serve as a broad shield against both known and unknown exposures across the lifetime. This is especially important given that some evidence shows that federal levels of permissible exposure for some solvents may be insufficient to protect workers against the health consequences of exposure."

Scientists uncover deja vu mystery

In a groundbreaking study, researchers from the Czech Republic and the United Kingdom have discovered a link between the déjà vu phenomenon and structures in the human brain, effectively confirming the neurological origin of this phenomenon. Despite past studies investigating this phenomenon in healthy individuals, no concrete evidence had ever emerged ... until now. The study is presented in the journal Cortex.

Led by the Central European Institute of Technology, Masaryk University (CEITEC MU) and Masaryk University's Faculty of Medicine in the Czech Republic, researchers discovered that specific brain structures have a direct impact on the déjà vu experience. The findings of their study showed that the size of these structures are considerably smaller in the brains of the people experiencing déjà vu, compared with individuals who had no personal experience with déjà vu.

The team from CEITEC MU, along with colleagues from other Brno research institutions as well as the University of Exeter in the United Kingdom succeeded in providing huge insight into this phenomenon that has perplexed many over the years.

The team observed how small structures in the brain's medial temporal lobes, in which memory and recollections originate, were considerably smaller in individuals with the occurrence of déjà vu than in individuals who have not experienced déjà vu. Their findings also showed that the more often the examined individuals experience déjà vu, the smaller the brain structures are.

"One hundred and thirteen healthy subjects underwent a structural examination of their brain by means of magnetic resonance and subsequently by using a new sensitive method for an automatic analysis of brain morphology (source-based morphometry) [and] the size of individual brain regions was compared among the individuals who have never experienced déjà vu and those who have experienced it," said lead author Milan Brázdil from CEITEC.

"Except for the presence of the examined phenomenon, both groups of individuals were fully comparable. When we stimulate the hippocampus, we are able to induce déjà vu in neurological patients. By finding the structural differences in hippocampus in healthy individuals who do and do not experience déjà vu, we have unambiguously proved that déjà vu is directly linked to the function of these brain structures. We think that it is probably a certain small "error in the system" caused by higher excitability of hippocampuses. It is the consequence of changes in the most sensitive brain regions which probably occurred in the course of the development of the neural system."

Experts say déjà vu, while fascinating, is not an uncommon experience. Between 60% and 80% of healthy individuals have reported occasional occurrences of déjà vu.

CN Annadurai: The Progenitor of Tamil Political Cinema

| by Gopalan Ravindran

Sept.15 2008 marked the beginning of the centenary celebrations of the man who caused the birth of not only Tamil political cinema, but also the cultural politics of cinema in Tamil Nadu. C N Annadurai, also known as CNA, and affectionately as Anna or elder brother, was not yet another politician, another ideologue and another dramatist testing the socially surcharged decades of 1940-1960 in Tamil Nadu. He was instrumental for making these decades socially surcharged, politically awakened and culturally rooted. He had the advantage of a rare personae that was rooted in an understanding of the Western social movements even as it sought to fuse the message of the same in the cultural contexts of Tamil Nadu. He was raring to go intellectually to new heights that remained out of bounds to his contemporaries and peers. CNA had his BA Hons. and MA in Economics from University of Madras during the 1930s, plunged thereafter into the social movement of Periyar EV Ramasamy, broke his relationship with Periyar in 1948 and started the political party, DMK, the same year. He became a parliamentarian in 1962 and the first non-congress Chief Minister of Tamil Nadu in 1967.

The above does not tell all about CNA. He was the first to see a connection between the masses and the means of communication they were more likely lap up. CNA was a prolific writer of political plays during the 1940s. He wrote 12 political plays, 86 political essays, 5 novels and 23 short stories. His first political play was Chandrodayam, written in 1943. He also acted in his plays. Towards late 1940s, CNA was gravitating towards the medium of film, on the strengths of the popularity of his political plays and the growing need for reaching out to the target groups of his political movement faster and in a more appealing manner. Three of his political plays were  made into films and marked the birth of Tamil political cinema. They are Velaikari(Servant Maid, 1949), Nalla Thambi (Good Young Brother, 1949) and Oor Iravu (One Night, 1951). The last film’s script was written by CNA during the course of one night, hence the title Oor Iravu (One Night).

Oor Iravu

Velaikari

Nalla Thambi

Endowed with a rare masterly touch in his writings and speeches, CNA proved to be the cynosure of young and old, rural and urban and illiterate and literate people of Tamil Nadu. His fans were swarming like bees whereever CNA went to deliver political speeches. He was a gentleman politician too, ever willing to respect fellow politicians and their political faiths.  He was more than willing to be polite and considerate to one and all in his party. He was a charismatic mass leader, despite being short and careless about how he dressed and looked in public. CNA is also remembered by his fans for his honest and spotless political career.

While he acted in his political plays, he did not go beyond scripting political films. His script for Nalla Thambi was meant to strengthen the political and social message bearer in his friend and admirer, N S Krishnan, the Tamil actor who taught a few lessons in political communication to CNA. CNA’s Velaikari and Oor Iravu were meant to consolidate the space earmarked by CNA for another friend, K R Ramasamy, as the first party actor. CNA’s inroads into Tamil cinema were later consolidated by the political films scripted by other younger leaders of the party such as M Karunanidhi, who launched the career of Sivaji Ganesan, with Parasakthi (1952), and his nephew, Murasoli Maran, the late union cabinet minister of commerce.

How allergies rise after treatments

MONASH UNIVERSITY

Share on print Australian researchers have discovered why people develop life-threatening allergies after receiving treatment for conditions such as epilepsy and AIDS. The research, by the University of Melbourne and Monash University, could lead to the development of a diagnostic test to determine drug hypersensitivity. Published today in Nature, the study revealed how some drugs inadvertently target the body's immune system to alter how it perceives it’s own tissues, making them appear foreign. The immune system then attacks the foreign nature of the tissues as if they were incompatible transplants. Professor Jamie Rossjohn from Monash University, who led the study with Professor James McCluskey of the University of Melbourne, and Professor Tony Purcell from the University of Melbourne’s Bio21 Institute, said the study showed the biological mechanisms by which a person's exact tissue type determined whether they would develop the drug allergy. "Our findings represent the culmination of a seven-year odyssey for the collaborative groups involved in this study," Professor Rossjohn said. "We have provided insight into a general mechanism of drug hypersensitivity and the HLA locus." Professor McCluskey said an entire class of drug allergy was likely to be explained by the discovery. “There are several drugs that can cause life-threatening skin rashes and other symptoms such as fever, diarrhea, muscle aches and pains," Professor McCluskey said. “A simple blood test may help to predict adverse reactions in the treatment of a broad range of conditions like AIDS, epilepsy, gout and infections.” The study was done in collaboration with the Queensland Institute for Medical Research and was supported by the Australian Research Council and the National Health and Medical Research Council of Australia.
