Forgotten memories still exist in the brain
Washington, Sept 10 (ANI): A new research by UC Irvine neuroscientists suggests that memories exist even when forgotten.
With the help of advanced brain imaging techniques, the study’s scientists discovered that a person’s brain activity while remembering an event is very similar to when it was first experienced, even if specifics can’t be recalled.
“If the details [...]
Eating at the ‘wrong’ time can lead to weight gain
Washington, September 4 (ANI): Eat at the right time of day if you actually want to shed those extra pounds, for an American study so suggests.

Bird flu virus strain leaves survivors at increased Parkinson’s disease risk
Washington, August 20 (ANI): An animal study conducted by experts at St. Jude Children’s Research Hospital has suggested that at least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson’s [...]
New drug helps rescue memory loss in mice with Alzheimer’s disease
Washington, July 15 (ANI): A drug similar to the one used in clinical trials for treatment of rheumatoid arthritis and psoriasis has been found to be effective against Alzheimer’s disease, say researchers.
The drug called PMX205 has been found to prevent inflamed immune cells from gathering in brain regions with Alzheimer’s lesions called amyloid plaques.
Cell [...]
How noise affects nervous system’s ability to transcribe sounds key to reading skills
Washington, July 14 (ANI): A new study conducted by Northwestern University researchers offers an unparalleled look at how noise affects the nervous system’s ability to transcribe sounds whose subtle differences are key to success with language and reading.
The study suggests that distinguishing such sounds is too much to ask of the nervous system of [...]
Eyes have given us real ’superpowers’, says expert
Washington, June 20 (ANI): Making a startling discovery, a scientist has claimed in his new book that the evolution of vision has provided humans with four real superpowers: telepathy, X-ray vision, seeing the future, and speaking with the dead.
And, as it turns out, these superpowers have been instrumental in shaping the way people interact with [...]
Bill and Melinda Gates pour thousands into unconventional health research
London, May 5 (ANI): Bill and Melinda Gates Foundation has thrown a lifeline to number of projects like creating an anti-viral tomato, a flu-resistant chicken and a magnet that can detect malaria, awarding 81 grants of one lakh dollar each in a bid to support innovative, unconventional global health research.
The five-year health research grants are [...]
Gene that switches on during epilepsy development identified
Washington, Apr 23 (ANI): Researchers at Wake Forest University School of Medicine have identified a gene that switches on during development of epilepsy.
The discovery made while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder.
In a study published this month in [...]
Retina works like a multi-layered jigsaw puzzle of receptive fields
Washington, April 7 (ANI): Scientists at the Salk Institute for Biological Studies have found that the retina works like a multi-layered jigsaw puzzle of jagged windows called receptive fields, through which about 1.25 million neurons view the world.
The researchers have revealed that these receptive fields fit together like pieces of a puzzle, preventing “blind spots” [...]

The National Conference of NOSI, NOSICON-09, was inaugurated by Delhi chief minister Sheila Dikshit on Friday at Fortis Hospital in Noida. Experts from [...]
Brain’s ‘wisdom centre’ found
London, Apr 5 (ANI): The seat of human wisdom has been identified by researchers at University of California in San Diego.
Using sophisticated brain scanning techniques, scientists were able to pinpoint parts of the brain that guide people when they face difficult moral dilemmas.
Boffins have found that humans respond by activating areas associated with the primitive [...]
Sleep clears the brain for next day’s learning
Washington, Apr 3 (ANI): Snoozing does more than help us recover from tensions and weariness – it helps the brain clear clutter accumulated after a long day’s work and make way for new learning.
Shutting down during the night helps the body to produce new synapses which connect brain cells.
Researchers at Washington University School of Medicine [...]
Mechanism that regulates movement of blood-forming stem cells in body identified
London, Mar 26 (ANI): Keck School of Medicine of the University of Southern California (USC) researchers have identified a mechanism that helps regulate the movement of blood-forming stem cells in the body.
The finding could lead to improvements in the efficiency of bone marrow transplants.
“By identifying [...]
How brain remembers single events
Washington, Mar 19 (ANI): One-time events-like a marriage proposal, a wedding toast, a baby’s birth-always hold that special place in our memory, and scientists have now found how brain remembers such events without them being repeated over time.

Musicians’ ‘well-tuned’ brains can identify emotion
Washington, Mar 4 (ANI): Searching for a guy who understands even your most subtle emotional signs? Well, then find a musician, suggests a new study, which found that artists’ brains are “well tuned” to identify emotions.
The Northwestern University study, which has been published in the latest issue of European Journal of Neuroscience, has provided biological [...]
Gene variant associated with both autism and gastrointestinal dysfunction identified
Washington, March 3 (ANI): A specific gene variant that links increased genetic risk for autism with gastrointestinal (GI) conditions has been identified by scientists at the University of Southern California (USC) and Vanderbilt University.
Dr. Pat Levitt, director of the Zilkha Neurogenetic Institute at the Keck School of Medicine of USC and chair-designate of the Department [...]
New brain area evolved to help humans with complex movements
Washington, Jan 13 (ANI): Neuroscientists at the University of Pittsburgh School of Medicine and Pittsburgh’s Veterans Affairs Medical Center have discovered that a new area of the cerebral cortex in brain has evolved, which has provided man and higher primates with the ability to pick up small objects and deftly use tools.
