A neurotransmitter that plays a role in learning new information, causes the skeletal muscle fibers to contract, and keeps the heart from beating too rapidly.

The sudden reveral of the resting potential, which initiates the firing of a neuron.

The slender tail-like extension of the neuron that transmits signals to the dendrites or cell bodyof other neurons and to muscles, glands and other parts of the body.

The structure that begins at the point where the spinal cord enlarges as it enters the brain and handles functions critical to physical survival. It includes the medulla, the pons and the reticular formation.

The part of the neuron that contains the nucleus and carries out the metabolic functions of the neuron.

In a neuron, the branchlike extensions of the cell body that receive signals from the other neurons.

A neurotransmitter that plays a role in learning, attention, movement and reinforcement.

Chemicals produced naturally by the brain that reduce pain and the stress of vigorous exercise and positively affect mood.

A neurotransmitter that affects the metabolism of glucose and nutrient energy stored in muscles to be released during strenuous exercise

Primary inhibitory neurotransmitter in the brain.

The specialization of one of the cerebral hemispheres to handle a particular function.

Controls right side of the body, coordinates complex movements, and, in most people, handles most of the language functions.

Specialized cell that conducts impulses through the nervous system and contains, a cell body, dendrites and axon.

A chemical substance that is released into the synaptic cleft from the axon terminal of the sending neuron, crosses a synapse and binds to appropriate receptor sites on the dendrites or cell body of a receiving neuron, influencing the cell either to fire or not.

A neurotransmitter affecting, eating, alertness and sleep.

The capacity of the brain to adapt to changes such as brain damage.

The slight negative electrical potential of the axon membrane of a neuron at rest, about -70 millivolts.

The process by which neurotransmitters are taken from the synaptic cleft back into the axon terminal for later use, thus terminating their excitatory or inhibitory effect on the receiving neuron.

Controls the left side of the body and, in more people, is specialized for visual-spatial perception.

Mood, sleep, appetite, impulsivity and aggression.

The junction where the axon terminal of a sending neuron communicates with a receiving neuron across the synaptic cleft.

The scientific study of behavior and mental processes.

• Behavior - Role of enviornment in shaping and controlling behavior 'learned'
• Psychoanalytic - 'unconscious mind' and early childhood experiences in determining behavior and thought. (happens in dreams) fears, wishes, desires
• Cognitive - mental process perception, thinking, and memory that underlie behavior. How you percieve a problem or situation
• Biological - biological processes and structures as well as heredityin explaning behavior. imbalance of chemicals in the brain. fix= medication, drugs

To use different approaches and theories depending on the PT.
