Definition Blue - Important Points Green - Important People & Contributions Nervous System: The Basics Neurons ? Individual cells in the nervous system that receive, integrate, and transmit information. They are basic links that allow communication within the Nervous System. Soma ? Cell Body of the neuron that contains the nucleus and much of cells normal organs. Dendrite ? Parts of a Neuron that receives information. Axon ? Long fiber that transmits information away to other neurons, muscles, or glands. Myelin Sheath ? Insulating Material that encases some Axons. It speeds up to transmission of information.

BIOLOGICAL BASES OF BEHAVIOR THE HUMAN BRAIN The influence of biology (sometimes called the neuroscience or biopsychological perspective) is growing. Some researchers predict that someday psychology will be a specialty within the field of biology. An understanding of the biological principles relevant to psychology is needed to understand current psychological thinking. The human brain consists of three major divisions; hindbrain, midbrain, and forebrain Major Division Subdivision Structures Prosencephalon?(Forebrain) Telencephalon Neocortex; Basal Ganglia; Amygdala; Hippocampus; Lateral Ventricles Diencephalon Thalamus; Hypothalamus; Epithalamus; Third Ventricle Mesencephalon?(Midbrain) Mesencephalon Tectum; Tegmentum; Cerebral Aqueduct

BIOLOGY 31.2 THE CENTRAL NERVOUS SYSTEM ? pp. 901-905 The Central Nervous System?Key Ideas Each of the major areas of the brain?the cerebrum, the cerebellum, the brain stem?are responsible for processing and relaying information. The spinal cord is the main communication link between the brain and the rest of the body. The brain reacts to excessive dopamine levels by reducing the number of receptors for the neurotransmitter. As a result, normal activities no longer produce the sensations of pleasure they once did. VOCABULARY: Reflex: quick, automatic response to a stimulus. Cerebrum: part of the brain responsible for voluntary activities of the body; ?thinking? region of the brain.
