Parietal, occipital
What term describes that the right and left hemisphere of the brain regulate different functions?
Lateralization
Respectively, what term describes a molecule that stimulates a response by binding to a receptor site and what term describes a molecule that blocks a response by binding to a receptor site?
Agonist, antagonist
Respectively, what is the name of the chemical messenger the endocrine system's glands secrete and which gland of the endocrine system is the master gland?
Hormones, pituitary
What neuroimaging technique uses magnetic fields and radio waves to produce computer-generated images that show brain anatomy?
MRI
Respectively, which of the four lobes of the cerebral cortex is located behind your forehead and is involved in speaking and judgment and which of the four lobes of the cerebral cortex is located just above your ears and is involved in hearing and recognition?
Frontal, temporal
What term describes a condition resulting from surgery for patients suffering from seizures that isolates the brain's two hemispheres by cutting the fibers connecting them?
Split brain
Respectively, what term describes the level of stimulation required to trigger a neural impulse and what term describes a brief electrochemical impulse traveling down the axon causing sodium channels to open, potassium channels to close, and the neuron becoming positively charged?
Threshold, action potential
What term describes the sensory (afferent) and motor (efferent) neurons that connect the central nervous system to the rest of the body?
Peripheral nervous system
Respectively, what brainstem structure begins where the spinal cord enters the skull and swells slightly and controls heartbeat and breathing and what brainstem structure helps coordinate movements and connects the hindbrain to the midbrain?
Name in the following order the three functions of the cerebral cortex that controls voluntary movements, registers body sensations, and is involved in higher mental functions?
Motor cortex, somatosensory cortex, association areas
For those with individual brains, when a person performs a perceptual task, activity increases in which hemisphere of the brain?
Right
Respectively, what part of the cerebral cortex consists of unmyelinated nerve cell bodies, dendrites, and glial cells and is involved in processing information and what type of underlying myelinated brain material transmits information from different parts of the body towards the cerebral cortex?
Grey matter, white matter
Respectively, what part of the peripheral nervous system controls the movements of our skeletal muscle and what part of the peripheral nervous system controls the glands and the muscles of our internal organs?
Somatic nervous system, autonomic nervous system
Respectively, what structure within the doughnut shaped limbic system is a cluster of neurons that play a role in aggression and fear and what structure within the doughnut shaped limbic system monitors blood chemistry and directs several maintenance activities (drinking, eating, breathing, body temperature)?
Amygdala, hypothalamus

Broca's area, Wernicke's area
What term describes that the mind processes information on two separate tracks, one operating at conscious level (explicit) and the other at an unconscious level (implicit)?
Dual Processing
