Studied by 5 peoplesensory (afferent) neurons
Neurons that carry incoming information from the body’s tissues and sensory receptors to the brain and spinal cord
agonist
A molecule that increases the action of a neurotransmitter
neurogenesis
The formation of new neurons
thalamus
The brains sensory control center, located on top of the brain stem; directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
glial cells
Cells in the nervous system that support, nourish, and protect neurons; they also play a role in learning, thinking, and memory
motor (efferent) neurons
Neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
pituitary gland
The endocrine system's most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands
refractory period
In neural processing, a brief resting pause that occurs after a neuron has fried; subsequent action potentials cannot occur until the axon returns to its resting state
interneurons
Neurons within the brain and spinal cord; communicate internally and process information between the sensory inputs and motor outputs
antagonist
A molecule that inhibits it blocks the action of a neurotransmitter
reticular formation
A nerve network that travels through the brain stem into the thalamus and plays an important role in controlling arousal
blindsight
A condition in which a person can respond to a visual stimulus without consciously experiencing it
adrenal glands
A pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine) that help arouse the body in times of stress
