Biology of behavior

A major inhibitory neurotransmitter. Undersupply linked to seizures, tremors, and insomnia.

• Dopamine

• Serotonin

• Norepinephrine

• Endorphins

• GABA (gamma-aminobutyric acid)

helps control alertness and arousal

• Dopamine

• Serotonin

• Norepinephrine

• Endorphins

• GABA (gamma-aminobutyric acid)

"morphine within"--natural, opiate-like neurotransmitters linked to pain control and to pleasure.

• Dopamine

• Serotonin

• Norepinephrine

• Endorphins

• GABA (gamma-aminobutyric acid)

3 types of _____ include

sensory, motor, interneurons

Balance and coordination

• Pons

• Medulla

• Spinal cord

• Cerebellum

sleep and arousal

• Pons

• Medulla

• Spinal cord

• Cerebellum

The intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body's ultimate control and information-processing center.

• Hypothalamus

• pituitary gland

• cerebral cortex

• reticular formation

A neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward.

• Hypothalamus

• pituitary gland

• cerebral cortex

• reticular formation

Under the influence of the hypothalamus, it regulates growth and controls other endocrine glands.

• Hypothalamus

• pituitary gland

• cerebral cortex

• reticular formation

the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla

• Amygdala

• Hippocampus

• corpus callosum

• Thalamus
