Probiotics alone or combined with prebiotics may help ease depression

Probiotics either taken by themselves or when combined with prebiotics, may help to ease depression, suggests a review of the available evidence.

Motherhood overrides the brain’s decision-making

Motherhood takes over the brain’s decision-making regions to prioritize caring for offspring, according to new research.

Neurobiology: How much oxygen does the brain need?

The brain has a high energy demand and reacts very sensitively to oxygen deficiency. Neurobiologists have now succeeded for the first time in directly correlating oxygen consumption with the activity of certain nerve cells.

Targeted deep brain stimulation to treat obsessive-compulsive disorder

Researchers have further refined the use of deep brain stimulation in the treatment of obsessive-compulsive disorder. By accurately localizing electrode placement in the brains of patients, the researchers were able to identify a fiber tract which is a…

Pioneering brain haemorrhage treatment reduces long-term disability in premature babies

Premature babies with serious brain haemorrhage treated with a ‘brain washing’ technique were twice as likely to survive without severe learning disability when compared with infants given standard treatment.

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.
