- sensory cortex
- association areas
- sensory neurons
- a neurons that carry incoming information from the sense receptors to the central nervous system (CNS).
- b two almond-shaped neural clusters that are components of the limbic system and are linked to emotion.
- c the area at the front of the parietal lobes that registers and processes body sensations.
- d neural "cables" containing many axons. These bundled axons, which are part of the peripheral nervous system (PNS), connect the central nervous system (CNS) with muscles, glands, and sense organs.
- e areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking.
5 Multiple Choice Questions
- function: influences movement, learning, attention, and emotion ; malfunctions: undersupply is linked to Alzheimer's disease.
- the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
- a condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (mainly those of the corpus callosum) between them.
- interconnected neural cells. With experience, networks can learn, as feedback strengthens or inhibits connections that produce certain results. Computer simulations of neural networks show analogous learning.
- function: affects mood, hunger, sleep, and arousal ; malfunctions: undersupply linked to depression. Prozac and some other antidepressant drugs raise serotonin levels.
5 True/False Questions
hypothalamus → 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.
electroencephalogram (EEG) → an amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp.
endocrine system → the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream.
nervous system → the body's speedy, electrochemical communication system, consisting of all the nerve cells of the peripheral and central nervous systems.
brainstem → the oldest part and central core of the brain, beginning where the spinal cord swells as it enter the skull; the brainstem is responsible for automatic survival functions.
