Spices in curries spruce up aging minds

...nts, such as vitamin E, have been shown to protect neurons in lab experiments but have had limited success in alleviating cognitive decline in patients with mild-to-moderate dementia. In the study conducted by Dr. Tze-Pin Ng and his team three groups were studied to correlate the effect of intake of curries...

Cell Wall of Pneumonia Bacteria Can Cause Brain and Heart Damage

How Brain Injury Leads to Seizures, Memory Problems

... system, abbreviated GABA(A). Glutamate stimulates neurons to fire, while GABA(A) inhibits that activity. “When lower levels of the KCC2 transporter weaken the dentate gyrus’s ability to act as a gatekeeper,” said Dr. Cohen, “neurons become more excitable, and seizures can occur.” In addition to its role ...

Brain Regions Do Not Communicate Efficiently in Adults with Autism

...es showed both over and under connectivity between neurons in different parts of the cortex, according to Michael Murias, a postdoctoral researcher who headed the study. “Our findings indicate adults with autism show differences in coordinated neural activity,” said Murias, “which implies poor internal com...

Eating Strawberries may boost memory

...fisetin protects and promotes survival of cultured neurons and boosts memory in healthy mice make it a promising candidate for further studies. Notes Maher, "This is the first time that the function of a defined natural product has been characterized at the molecular level in the central nervous system and a...

Methamphetamine may Protect Neurons after Stroke Attack

...red in rats and gerbils after a stroke//, protects neurons upto 80-90%. It was used initially to aggravate st...amphetamine. Later, dissection revealed that their neurons showed hardly any difference from the normal gerbils', unlike the untreated ones where great damag...

The 'Chip' in Your Brain!

...h headed by Prof.O'Rielly, has elucidated that the neurons (specialized cells of the brain) in the pre-frontal cortex, are binary just like the digital computers, having to be either "on" or "off" which is in turn controlled by the Basal ganglia, which functions like a switch which allows a person to operate...

Clues to the Mystery of Lou Gehrig's Disease

... Tests using tissue samples showed that the motor neurons of ALS patients and the frontal and temporal neurons of frontotemporal lobar degeneration patients contain large amounts of ubiquitinated TDP-43 in their...

Slow brain waves integral in coordination of complex activity

...g high-gamma-related neural activity in individual neurons to transmit information," said Knight. "When you stop reading and begin to type, theta rhythms oscillate in motor structures, allowing you to plan and execute your motor response by way of high gamma. Simple, but effective." The findings are report...

Epilepsy Treated with Implanted Devices

...seizure, brain waves from thousands of the brain's neurons start firing together. It's the opposite of what happens in a heart attack when the heart muscle beats wildly. "The idea behind the RNS is that a small electrical discharge, less than that of a battery across your thumb, will be enough to stop a seiz...

Study Finds Parkinson’s Cell Death Blocked by Stopping Inflammatory Facto

Punch-Drunk Effect- Every blow matters

According to the researchers, around 20% of the professional boxers develop chronic traumatic brain injury due to long period of exposure to frequent blows to the hea...

Gene May Regulate Cellular Aging

...ral stem cells, progenitor cells that can form new neurons and other brain cells. The team showed that p16INK4a increases markedly in those cells with aging. Moreover, p16INK4a -deficient neural stem cells work better and don't age to the same extent that wild-type (normal) stem cells do, Sharpless said. Dr...

Awake or not?

About 50 percent of people with such injuries recover some awareness in the first year after the injury, studies find; very few do so afterward.

Greater g factor in men responsible for sex differences in general mental ability

...study in Denmark documented that men have 15% more neurons than women (22.8 versus 19.3 billion). Over two-dozen Magnetic Resonance Imaging studies have confirmed a brain-size/IQ correlation of about 0.40. So, if males average a larger brain, shouldn't they also average a higher IQ score? British psycholog...

Link between stem cells and aging

... till old, had almost double the normal numbers of neurons in their forebrains Over expressing Ink4a in young mice also reduced the number of islet cells hastening the aging of the mice albeit prematurely. The researchers were led to think that the protein protects against cancer by offsetting the reproducti...

Breakthrough In The Identity Of Compounds That Encourage Stem Cell Growth

"This study opens doors to new therapeutic approaches for a wide range neurological disorders and injuries that were once consi...
