Sniffing out smell: How the brain organizes information about odors

Neuroscientists describe for the first time how relationships between different odors are encoded in the brain. The findings suggest a mechanism that may explain why individuals have common but highly personalized experiences with smell, and inform eff…

Tests of hearing can reveal HIV’s effects on the brain

New findings are shedding further light on how the brain’s auditory system may provide a window into how the brain is affected by HIV.

Nitrous oxide may bring relief to veterans suffering from PTSD, new study suggests

A small pilot study provides an early glimpse of how some veterans struggling with PTSD may benefit from one simple, inexpensive treatment involving nitrous oxide, commonly known as laughing gas.

How does our brain fold? Study reveals new genetic insights

Problems with brain folding are linked with neurological conditions like autism, anorexia and schizophrenia, but there are currently no ways to detect, prevent or treat misfolding. New research offers genetic insights into the folding process, an impor…

Why memory-forming neurons are vulnerable to Alzheimer’s

Scientists have used advanced technology to ‘micro-dissect’ the first brain cells to perish in Alzheimer’s disease. The result is a short list of genes that could represent new drug targets.

Life-hack: Rituals spell anxiety relief

Researchers are examining the important roles rituals play in reducing our anxiety levels.

Lab-grown ‘mini-brains’ suggest COVID-19 virus can infect human brain cells

Researchers have found that organoids known as ‘mini-brains’ can be infected by the SARS-CoV-2 virus that causes COVID-19.

Auditory hallucinations rooted in aberrant brain connectivity

A study reports that auditory hallucinations, a phenomenon in which people hear voices or other sounds, may arise through altered brain connectivity between sensory and cognitive processing areas.

Novel pathology could improve diagnosis and treatment of Huntington’s and other diseases

Scientists have discovered a novel pathology that occurs in several human neurodegenerative diseases, including Huntington’s disease. The article describes how SAFB1 expression occurs in both spinocerebellar ataxias and Huntington’s disease and may be …

Discovery of new step in how brain cells work could lead to new therapies for epilepsy

Researchers have identified a critical new step in how brain cells function in people with one of the most common forms of epilepsy. This could lead to new treatment approaches for people with drug-resistant epilepsy.
