Researchers throughout the world are pursuing a variety of new ways to repair or replace neurons and other cells in the brain. For the most part, these experimental approaches are still being worked out in animals and cannot be considered therapies for humans at this time.

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

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.

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

A stressful situation activates three major communication systems in the brain, all of which regulate bodily functions.

Medical professionals have come to rely on even more specialized forms of the MRI machine, each suited to spotting specific warning signs.

Optical imaging relies on shining weak lasers through the skull to visualize brain activity. These techniques are inexpensive and relatively portable. They are also silent and safe: Because only extremely weak lasers are used, these methods can be used to study everyone, even infants.

The brain uses a variety of chemicals called neurotransmitters to communicate between brain cells.

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