The Cerebrum:?The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. Here is a visual representation of the cortex: What do each of these lobes do? Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli Occipital Lobe- associated with visual processing Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech

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.

The Cerebrum Information processing centered in cerebrum Structure Telencephalon gives rise to cerebrum Divided into right and left cerebral hemispheres ? outer covering of gray matter Cerebral cortex, internal white matter, and groups of neurons (basal nuclei) located deep within white matter ? important for planning and learning movement sequences Damage- cerebral palsy Cerebral cortex (largest/most complex) ? sensory information analyzed Right/left hemispheres ? right side responsible for left side of body; left side responsible for right side of body Corpus callosum (thick band of axons) allows communication between right and left cerebral cortex Damage to cerebrum early in development- Normal functions radiated elsewhere
