The region consisting of portions of the cerebrum and diencephalon that is involved in emotional states and behavior

Nuclei that regulate the contraction of smooth muscle in blood vessel walls

The portion of the brain controlling the autonomic nervous system

Technique that produces a picture of brain activity levels in different parts of the brain

Technique that measures electric currents in the brain

X-ray technique that provides photos of bone, cavities, and lesions

Technique used to visualize soft tissue, such as scar tissue, hemorrhages, and tumors that does not use x-rays

A motor nerve controlling the trapezius, sternocleidomastoid, and larynx muscles

The nerve that controls contraction of a single eye muscle

The nerve that carries visual impulses from the eye to the brain

The most important sensory nerve of the face and head

The nerve that supplies most of the organs in the thoracic and abdominal cavities

The nerve that supplies the muscles of facial expression

The nerve that carries sensory impulses for hearing and equilibrium

A chronic brain disorder that usually can be diagnosed by EEG

Damage to brain tissue caused by a blood clot, ruptured vessel, or embolism

Loss of the power of expression by speech or writing

- Involved in emotional states and behavior
- Borders between the cerebrum and the diencephalon
- Links the conscious functions of the cerebral cortex and the autonomic functions of the brain stem

- A connecting link between the cerebellum and thes rest of the nervouse system
- Regulating respiration is a reflex action that is integrated in this
