Lithium can reverse radiation damage after brain tumor treatment

Children who have received radiotherapy for a brain tumor can develop cognitive problems later in life. In their studies on mice, researchers have now shown that the drug lithium can help to reverse the damage caused long after it has occurred. The res…

Slowing the progression of multiple sclerosis

Over 77,000 Canadians are living with multiple sclerosis, a disease whose causes still remain unknown. Presently, they have no hope for a cure. Researchers have now identified a molecule named ALCAM which, once blocked, delays the progression of the di…

Firefighters can ease one another’s job stress, but loving spouses may increase it

Strong same-sex friendships among male firefighters can help cut down on their stress — but loving relationships with their wives may increase anxiety for those who constantly face danger, according to a new study.

Why only some post-stroke survivors can ‘copy what I say’

Flame-retardant exposure increases anxiety, affects social behaviors in prairie vole

New research shows that early life exposure to a commonly used flame-retardant mixture increases anxiety and affects socioemotional behaviors in prairie voles, particularly in females.

Good noise, bad noise: White noise improves hearing

White noise is not the same as other noise — and even a quiet environment does not have the same effect as white noise. With a background of continuous white noise, hearing pure sounds becomes even more precise, as researchers have shown. Their findin…

New pathways in brain’s amygdala

Researchers are pioneering an innovative brain study that sheds light on how the amygdala portion of the brain functions and could contribute to a better understanding of post-traumatic stress disorder, anxiety, depression and Alzheimer’s disease.

Scientists shed new light on neural processes behind learning and motor behaviors

Researchers have provided new insight into the neural processes behind movement and learning behaviors, according to a new study.

Specific neurons that map memories now identified in the human brain

Neuroengineers have found the first evidence that individual neurons in the human brain target specific memories during recall. They studied recordings in neurosurgical patients who had electrodes implanted in their brains and examined how the patients…

Mothers’ pregnancy-related anxiety may alter how infants’ brains respond to sad speech

A study shows a correlation between mothers’ self-reported pregnancy-related anxiety, and babies’ blood flow to brain areas responsible for emotional responses when listening to sad speech
