In response to signals from a brain region called the hypothalamus, the adrenal glands secrete glucocorticoids, hormones that produce an array of effects in response to stress.

Much faster than a traditional MRI, MEG can be used to provide even more information about brain activity.

Touch is the sense by which we determine the characteristics of objects: size, shape, and texture.

Molecules that are important in brain development may help treat or prevent brain injuries and disorders.

From the first large studies monitoring the mental functioning of the same group of healthy humans over many years, scientists have uncovered unexpected results.

One of the most common and least understood neurobiological disorders, Tourette syndrome is an inherited disorder that affects about 200,000 Americans. Males are affected three to four times as often as females.

PET is one of the most important techniques for measuring blood flow or energy consumption in the brain. This method of measuring brain function is based on the detection of radioactivity emitted when positrons, positively charged particles, undergo radioactive decay in the brain.

Our best insights into how the normal brain ages come from long-term studies of the nervous system that began decades ago.

The messages sent from one brain cell to another are the basis of brain function. Brain cells communicate through both electrical and chemical means.

The discovery in the late 1950s that the level of dopamine was decreased in the brains of Parkinson’s patients was followed in the 1960s by successful treatment with the drug levodopa, which is converted to dopamine in the brain. This historical event is one of the greatest medical breakthroughs in the field of neurology.
