How bat brains listen out for incoming signals during echolocation

Neuroscientists have discovered a feedback loop that modulates the receptivity of the auditory cortex to incoming acoustic signals when bats emit echolocation calls. The researchers show that information transfer in the neural circuits involved switche…

A brain mechanism underlying the evolution of anxiety

New research using genome editing technology has allowed scientists to create a model and assess a gene mutation associated with neuropsychiatric disorders in humans. The study has revealed how the mutation functions in the brain and affects anxiety an…

A new therapeutic drug for Alzheimer’s disease without inflammatory side effects

Although Aduhelm, a monoclonal antibody targeting amyloid beta (A?), recently became the first US FDA approved drug for Alzheimer’s disease (AD) based on its ability to decrease A? plaque burden in AD patients, its effect on cognitive improvement is st…

Our brain is a prediction machine that is always active

Our brain works a bit like the autocomplete function on your phone — it is constantly trying to guess the next word when we are listening to a book, reading or conducting a conversation. Contrary to speech recognition computers, our brains are constan…

Social isolation and loneliness increase the risk of death from heart attack, stroke

Social isolation and loneliness are prevalent in the U.S., and they have harmful effects on heart and brain health. Older adults and people in socially vulnerable groups, such as individuals from disenfranchised racial or ethnic groups, people with dis…

The brain already benefits from moderate physical activity, study shows

Even moderate physical activity has a positive effect on the brain. Researchers deduce this from examinations of 2,550 participants of the Bonn ‘Rhineland Study’. According to the study’s findings, certain areas of the brain are larger in physically ac…

Seeing through someone else’s eyes: Proposing objective criteria to examine subjective experiences

Researchers propose objective criteria to examine subjective experiences and reveal their neuronal basis.

Microscopic blood vessel disease in the brain’s white matter associated with worse cognition in Alzheimer’s

Disease of the microscopic blood vessels that feed the white matter of our brain is associated with worse cognitive function and memory deficits in individuals with Alzheimer’s, scientists report.

Advancing dynamic brain imaging with AI

New research introduces a novel, AI-based dynamic brain imaging technology alternative which could map out rapidly changing electrical activity in the brain with high speed, high resolution, and low cost.

Iron buildup in brain linked to higher risk for movement disorders

Researchers report that individuals with two copies of a gene mutation show evidence of substantial iron buildup in regions of the brain, raising risk for movement disorders like Parkinson’s disease.
