The ability to react quickly in response to threatening events has been with us since the time of our earliest ancestors.

A major breakthrough in understanding how the brain accomplishes learning and memory began with the study of a person known by his initials, H.M.

Cells within the nervous system, called neurons, communicate with each other in unique ways. The neuron is the basic working unit of the brain.

Brain injury is all too common, but treatments are being improved constantly. Those who survive a brain injury face a lifetime of disability, with economic costs approaching $60 billion annually.

The brain uses some unconventional means to communicate.

The two halves of the nervous system work together in order for your body to properly communicate its sensations and needs.

Most medicines today were developed using trial-and-error techniques, which often do not reveal why a drug produces a particular effect. But the expanding knowledge gained from molecular biology methods makes safer and more effective drugs possible.

Providing a high-quality, three-dimensional image of organs and structures inside the body without X-rays or other radiation, MRIs are noninvasive and unsurpassed in the anatomical detail they show.

Sleep is crucial for concentration, memory, coordination, and even emotional health. Research holds promise for devising new treatments to allow millions of people to get a good night’s sleep.

As our understanding of the processes that underlie brain damage progresses, it becomes possible to use small-molecule drugs, such as antibiotics and anti-tumor drugs, to alter these processes.
