An insertion of a thin, insulated electrode into the brain through which an electrical current is sent, destroying the brain cells at the tip of the wire.

• lesioning

• electroencephalograph

• medulla

• pons

A machine designed to record the electrical activity of the cortex below the skull.

• lesioning

• electroencephalograph

• medulla

• pons

The first large selling at the top of the spinal cord, forming the lowest part of the brain, which is responsible for life-sustaining functions such as breathing, swallowing, and heart rate.

• lesioning

• electroencephalograph

• medulla

• pons

The larger swelling above the medulla that connects the top of the brain to the bottom and that plays a part in sleep, dreaming, left-right body coordination and arousal.

• lesioning

• electroencephalograph

• medulla

• pons

An area of neurons running through the middle of the medulla and the pons and slightly beyond that play a role in general arousal, alertness, and sleep.

• hypothalamus

• thalamus

• cerebellum

• reticular formation

Part of the lower brain located behind the pons that controls and coordinates involuntary, rapid, fine motor movement, and may have some cognitive functions.

• hypothalamus

• thalamus

• cerebellum

• reticular formation

The part of the limbic system located in the center of the brain, this structure relays sensory information from the lower part of the brain to the proper areas of the cortex and processes some sensory information before sending it to its proper area.

• cerebellum

• thalamus

• hypothalamus

• reticular formation

Small structure in the brain located below the thalamus and idrectly above the pitutiatry gland, responsible for motivational behavior such as sleep, hunger, thirst, and sex.

• thalamus

• hypothalamus

• pons

• cortex

The tendency of the body to maintain a steady state.

• amygdala

• cortex

• homeostasis

• hypothalamus

A curved structure located within each temporal lobe, responsible for the formation of long-term declarative memories.

• amygdala

• homeostasis

• occipital lobe

• hippocampus
