Why we don’t all develop posttraumatic stress disorder after trauma

Researchers show why only a subset of individuals exposed to trauma develop posttraumatic stress disorder (PTSD). The research, centered on the body’s stress hormone response, could pave the way for more targeted treatments for PTSD.

When dads are feeling a bit depressed or anxious, how do kids fare?

A team of researchers has found that slightly higher, but mild anxious or depressive symptoms in fathers were associated with fewer behavioral difficulties in the first years of elementary school and better scores on a standardized IQ test in their chi…

Brain implant may enable communication from thoughts alone

A speech prosthetic developed by a collaborative team of neuroscientists, neurosurgeons and engineers can translate a person’s brain signals into what they’re trying to say. The new technology might one day help people unable to talk due to neurologic…

Location of strong sense of discomfort in brain found

Researchers have identified a new neural circuit in the brain which produces a strong sense of discomfort when activated. The discovery also allows them to show for the first time that the subthalamic nucleus, a structure in the brain that controls vol…

Research team discovers new role of cerebellum in coordinating the brain network essential for social recognition memory

Researchers discovered the cerebellum coordinates the brain network essential for social recognition memory. 

Rats have an imagination, new research suggests

Researchers have developed a novel system to probe a rat’s thoughts, finding that animals can control their brain activity to imagine remote locations.  

One sleepless night can rapidly reverse depression for several days
