Facial Paralysis Stigma Takes Emotional Toll, Especially When Acquired Later in Life

People with facial paralysis are more likely to face depression and anxiety than the general population, especially if the paralysis occurs later in life rather than at birth, according to a recent ... read more

Blue Light Triggers Memory and Emphatic Fear in Mice Via a Non-Invasive Approach

Researchers have engineered an improved biological tool that controls calcium (Ca2+) levels in the brain via blue light. This monster-OptoSTIM1 causes a change in mice's fear learning behavior ... read more

Glutamate in the Brain Has Unexpected Qualities, Researchers Show With New Analysis Method

Researchers have achieved something long thought almost impossible -- counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a ... read more

Treatment for Depression Must Also Restore Proper Functioning of the Blood-Brain Barrier

To better treat people with depression, not only must we treat the neurons affected by the disease, but we must also restore the integrity of the barrier that regulates exchanges between blood ... read more
