Researchers have discovered of a new type of gene mutation that reduces fear and anxiety, and increases social interaction. The researchers employed gene manipulation technology to remove the P4h-tm gene from the mouse genome and found an unexpected ch…

People who don’t give up on their goals (or who get better over time at not giving up on their goals) and who have a positive outlook appear to have less anxiety and depression and fewer panic attacks, according to a study of thousands of Americans ove…

Caring for family members with dementia — which is on the rise in the US — causes significant emotional and physical stress that increases caregivers’ risk of depression, anxiety and death. A new method of coping with that stress by teaching people h…

In a first of its kind study, researchers have used cellular resolution in vivo two-photon calcium imaging in mice to investigate changes in the local repertoire of neuronal micro states during anesthesia. The team found that anesthesia disrupts the nu…

Scientists have discovered a new method for quickly and efficiently mapping the vast network of connections among neurons in the brain. Researchers combined infrared laser stimulation techniques with functional magnetic resonance imaging in animals to …

For decades scientists have been searching for a way to watch a live broadcast of the brain. Neurons send and receive massive amounts of information — toe itches! Fire hot! Garbage smells! — at speeds up to 270 miles per hour. Now, with a new microsc…

Researchers performed the first comprehensive analysis of the genes altered in individual brain cells of patients with Alzheimer’s disease, allowing them to identify the distinctive cellular pathways affected in neurons and other types of brain cells.

Brain tumors are the leading cause of non-accidental death in children in Canada, but little is known about when these tumours form or how they develop. Researchers have recently identified the cells that are thought to give rise to certain brain tumor…

A new study sheds light on understanding the extensive individual differences in how we sense odors. By showing that small changes in a single olfactory receptor gene can affect how strong and pleasant a person finds an odor, the findings expand unders…

When rodents get infected by Toxoplasma gondii, the single-celled brain parasite that causes toxoplasmosis, they become hyperactive risk-takers. Researchers show for the first time that it’s possible to reverse that behavioral change.
