Researchers use technology to show organoids respond to external sensory s
Updated : 3 years, 2 months ago IST
A team of engineers and neuroscientists has demonstrated for the first time that human brain organoids implanted in mice have established functional connectivity to the animals' cortex and responded to external sensory stimuli. The implanted organoids reacted to visual stimuli in the same wa

Study sheds light on how the brain stores remote fear memory
Updated : 3 years, 2 months ago IST
A remote fear memory is a memory of traumatic events that occurred in the distant past, a few months to decades ago. A University of California, Riverside, mouse study published in Nature Neuroscience has now spelt out the fundamental mechanisms by which the brain consolidates remote fear me

Study reveals how neurons respond to aged-related iron accumulation
Updated : 3 years, 3 months ago IST
Iron (Fe) accumulates in the brain cortex with aging. A plethora of studies indicate that progressive iron accumulation in the substantia nigra (SN) in the aged human brain is a major risk factor for Parkinson's disease (PD) and other neurodegenerative diseases, but not everyone. This is bec

New findings on neuronal activities in the sensorimotor cortex: Research
Updated : 3 years, 3 months ago IST
An interdisciplinary research team at the University of Freiburg has found important clues about the functioning of the sensorimotor cortex. The new findings on neuronal activities in this brain area could be helpful for the further development and use of so-called neuroprostheses. These hav

Laser therapy is beneficial in treating short-term memory problems: Study
Updated : 3 years, 3 months ago IST
Scientists at the University of Birmingham in the UK and Beijing Normal University in China, demonstrated that the therapy, which is non-invasive, could improve short-term, or working memory in people by up to 25 per cent.

Silent synapses are abundant in the adult brain: Study
Updated : 3 years, 3 months ago IST
Neuroscientists discovered that the adult brain contains millions of 'silent synapses' immature connections between neurons that remain inactive until they're recruited to help form new memories.

Scientists create new map of developing cerebral cortex
Updated : 3 years, 3 months ago IST
Scientists at the UNC School of Medicine have mapped the surface of the cortex of the young human brain with unprecedented resolution, revealing the development of key functional regions from two months before birth to two years after.

Study finds that children learn more quickly than adults
Updated : 3 years, 3 months ago IST
If you've ever had the feeling that your elementary school kids were "smarter" than you or at least capable of picking up new information and skills faster, a new study in Current Biology on November 15 suggests you're absolutely right.

Brain area thought to impart consciousness, behaves instead like Internet
Updated : 3 years, 3 months ago IST
The legendary scientist Francis Crick first postulated in 2005 that the brain region known as the claustrum is the seat of consciousness. Researchers now posit that Crick may have been incorrect: They developed a new theory built on data that the claustrum behaves more like a high-speed Inte

Rare mutations may have big impact on schizophrenia pathology
Updated : 3 years, 4 months ago IST
Researchers have long searched for genetic influences in schizophrenia, a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. However, the disease's genetic mutations have been identified in only a small fraction few

Study finds brain changes in autism are far more sweeping than previously
Updated : 3 years, 4 months ago IST
The study, published today in Nature, represents a comprehensive effort to characterize ASD at the molecular level. While neurological disorders like Alzheimer's disease or Parkinson's disease have well-defined pathologies, autism and other psychiatric disorders have had a lack of defining p
