Document Summary
Nueron a nerve cell; the basic building block of the nervous system. The adrenals secrete the hormones epinephrine (adrenaline) and norepinephrine (noradrenaline) which help to arouse the body in times of stress pituitary gland the endocrine system"s most influential gland.

A brain lesion is a naturally or experimentally caused destruction of brain tissue. Eeg eletroencephalogram; an amplified recording of the waves of electrical activity that sweep across the brain"s surface. These waves are measured by electrodes placed on the scalp. Pet positron emission tomography scan; a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task. Broca"s area controls language expression -- an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech.
