Psyc 2275 - lecture 3 - brain structures and regions. Gray matter constitutes the outer-most layer of the brain (4mm thick) White matter constitutes the axons that connect cells of the cortex. Corpus callosum connects the two hemispheres of the brain. The cortex is responsible for higher-order processing abilities. The brain is organized into lobes that have different functions: frontal: executive processes, temporal: hearing, smelling, recognizing and remembering, parietal: integration of sensory info from different modalities, occipital: processes visual information. A collection of neuron cell bodies in the central nervous system. Basal ganglia: highly interconnected network of nuclei that are important for different aspects of movement (motor control/action selection: damage causes huntington"s disease and parkinson"s disease, contains the caudate nucleus, putamen, globus pallidus. Limbic system: interconnected nuclei important for learning and memory, fear and emotion, and perceptions of odor: contains the olfactory bulb, amygdala, hippocampus, mammilary body, and cingulate gyrus.
