A new study reports people use confirmation bias, even when a decision they make has little to no consequence.

Analysis of data captured during a long-term study of aging adults shows that those who report being very sleepy during the day were nearly three times more likely than those who didn’t to have brain deposits of beta amyloid, a protein that’s a hallmark for Alzheimer’s disease, years later.

Researchers have created a computational model that helps explain how mental images drawn from memory can be explained by the firing of specific neurons.

According to a new study, probiotics may not be as effective as most believe. Researchers report many people’s digestive tracts prevent standard probiotics from successfully colonizing them.

A team of researchers has analysed what happens in the brain when humans want to voluntarily forget something.

Whether an individual develops a neurodevelopmental disorder like autism or ADHD and the severity of that disorder depends on genetic changes beyond a single supposedly disease-causing mutation. A new study led by researchers at Penn State reveals that the total amount of rare mutations — deletions, duplications, or other changes to the DNA sequence — in a person’s genome can explain why individuals with a disease-associated mutation can have vastly different symptoms. A paper describing the study appeared today in the journal Genetics in Medicine.

New research has shed new light on genetic processes that may one day lead to the development of therapies that can slow, or even reverse, how our cells age.

Researchers have identified a new neural mechanism that contributes to long term stress and PTSD. The study reports the mechanism is mediated by brain fluid in areas associated with stress response.

Finally this week, is the popular claim that the brain feels no pain substantiated? A new paper looks at the accuracy of the belief.
