A neurotransmitter that enables learning and memory and also triggers muscle contraction.

A neural impulse: a brief electrical charge that travels down an axon, The action potential is generated by the movement of positively changed atoms in and out of channels in the axon's membrane.

A pair of endocrine glands just above the kidneys. The adrenals secrete the hormones epinephrine (adrenaline) and norepinephrine (noradrenaline), which help to arouse the body in times of stress.

Excite neurons by mimicking natural neurotransmitters or blocking their reuptake to keep more of them in your system. (pretends to be something else)

A progressive and irreversible brain disorder characterized by gradual deterioration of memory, reasoning, language, and finally, physical functioning.

Two lima bean-sized neural clusters that are components of the limbic system and are linked to emotion.

Inhibit neural impulses by blocking receptor sites or diminishing their release.

Impairment of language, usually caused by left hemisphere damage either to Broca's area (impairing speaking) or to Wernicke's area (impairing understanding).

Areas of the cerebral cortex that are not involved in primary motor or sensory functions: rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking.

The part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses: its parasympathetic division calms.

The extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons of to muscles or glands.

A branch of psychology concerned with the links between biology and behavior. (some biological psychologists call themselves behavioral neuroscientists, neuropsychologists, behavior genetics, physiological psychologists, or bio-psychologists.)

The study of the relative power and limits of genetic ad environmental influences on behavior.

The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull: the brain-stem is responsible for automatic survival functions.

The brain and spinal cord.
