Men's brains diminish faster than women's, claims study

New York: While the human brain tends to shrink with age, men’s brains diminish faster than women’s which may explain why the fairer sex are more likely to stay mentally sharp in their later years, finds a study led by a researcher of Indian-origin. The study noted that the brain’s metabolism slows as people grow […]

Train your brain to form good habits through repetition

New York: If you want to form good habits — like going to the gym and eating healthy — then you need to train your brain by repeating actions until they stick, a new study suggests. The researchers have created a model which shows that forming good (and bad) habits depends more on how often […]

How one good meal makes us happy twice

London: If you thought a good meal satisfies only your taste buds, you could not be further from the truth. New research suggests that our brain rewards twice per meal — once when you eat and then again when the food reaches your stomach. The findings published in the journal Cell Metabolism suggest that a […]

Bigger brain could make you only a little smarter than others

New York: A bigger brain alone cannot guarantee you a pass to the best jobs in the world as researchers have found that an increase in brain volume contributes very little to a person’s intelligence and educational attainment.

The findings, published in the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, provide clues as to which regions of the brain could be at the root of symptoms, such […]

Sex, aggression overlap in male brains: Study

New York: Brain structures that control aggressive and sexual behaviour are controlled differently in females, but they tend to overlap in males, a new study has found. Male circuits for sex and aggression were earlier traced to a distinct part of the hypothalamus, known as the ventromedial hypothalamus, or VMHvl — located on the underside […]

Excessive brain cell growth after head injury bad for brain

New York: Turning conventional wisdom on its head, researchers including one of Indian-origin, have found that the excessive burst of new brain cells after a traumatic head injury that scientists have traditionally believed helped in recovery could instead lead to epileptic seizures and long-term cognitive decline. The findings published in the journal Stem Cell Reports […]

How the brain copes with ageing

New York: As the brain begins to shrink with age, it increases communication between the two brain hemispheres to help older people compensate for the negative aspects of ageing, new research has found. “This study provides an explicit test of some controversial ideas about how the brain reorganises as we age,” said lead author Simon […]

Emotionally unstable have different brain structure

London: The orbito-frontal cortex, an area in the lower frontal lobe, is smaller in the people who have problems with regulating emotions, a study says. People vary in how often they become happy, sad or angry, and also in how strongly these emotions are expressed. However, there are people who find it difficult to regulate […]

Binge eating
Hormone deficiency in brain may cause binge eating

New York: Absence of an hormone in the brain may trigger overeating behaviour in people who eat for pleasure rather than hunger, researchers report. In the lab experiments, researchers found that when the “glucagon like peptide-1” (GLP-1) hormone was reduced in the central nervous system of mice, they overate and consumed more high fat food. […]

Simple test to spot Alzheimer's risk

New York: An affordable non-invasive test that detects electrical activity in the brain may be used to spot people who are at the risk of Alzherimer’s, say researchers. Electroencephalogram (EEG) technology can be used to measure cognitive deficits in people with amnestic mild cognitive impairment (aMCI). Individuals with aMCI are at twice the risk of […]

Our brain has a map for social navigation

New York: The brain region that helps us remember locations and distances can also guide us how emotionally close we are to others, a study has found. The team from Mount Sinai Hospital focused on evidence for the existence of a “social map” in the hippocampus, the part of the brain that remembers locations in […]
