The "new brain," responsible for the most sophisticated information processing in the brain; contains four lobes.
Bridge of fibers passing information between the two cerebral hemispheres
A curved elongated ridge that extends over the floor of the descending horn of each lateral ventricle of the brain, that consists of gray matter covered on the ventricular surface with white matter, and that is involved in forming, storing, and processing memory.
A roughly almond-shaped mass of gray matter deep inside each cerebral hemisphere, associated with the sense of smell. The amygdala is involved in the processing of emotions such as fear, anger and pleasure.
The "old brain," which controls basic functions such as eating and sleeping and is common to all vertebrates.
The part of the brain that controls bodily balance.
The part of the brain extending from the medulla through the pons and made up of groups of nerve cells that can immediately activate other parts of the brain to produce general bodily arousal.
The part of the brain located in the middle of the central core that acts primarily to relay information about the senses.
A tiny part of the brain, located below the thalamus, that maintains homeostasis and produces and regulates vital behavior, such as eating, drinking, and sexual behavior.
Responsible for communication between brain and the rest of the body; involved in simple reflexes.
A small central part of the brain stem. It acts as a relay station for auditory and visual information.
One of two enlargements at the terminus of the olfactory nerve at the base of the brain just above the nasal cavities. It relays sensory signals to the olfactory tract and deals with sense of smell.
"master" gland that regulates other endocrine glands.
Responsible for regulating largely unconscious functions such as breathing and circulation.
The part of the brain that controls eating, aggression, and reproduction.
Involved in sleep and arousal.
The four major sections of the cerebral cortex: frontal, parietal, temporal, and occipital.
The site in the brain of the tissue that corresponds to each of the senses, with the degree of sensitivity related to the amount of tissue.
One of the major regions of the cerebral cortex; the site of the higher mental processes, such as though, language, memory, and speech.
Changes in the brain that occur throughout the life span relating to the addition of new neurons, new interconnections between neurons, and the reorganization of the information-processing areas.
The creation of new neurons.
Symmetrical left and right halves of the brain that control the side of the body opposite to their location.
The dominance of one hemisphere of the brain in specific functions, such as language.
A procedure in which a person learns to control through conscious thought internal physiological processes such as blood pressure, heart and respiration rate, skin temperature, sweating, and the constriction of particular muscles.
