Document Summary
Prefrontal cortex performs brain"s executive functions: planning, selecting, and coordinating thoughts. Auditory cortex conscious processing of sounds. Amygdala neural centers in the limbic system linked to emotion. Hippocampus a structure in the limbic system linked to memory. Corpus callosum axon fibers connecting two cerebral hemispheres. Thalamus relays messages between lower brain centers and cerebral cortex. Hypothalamus controls maintenance functions such as eating; helps govern endocrine system; linked to emotion and rewards. Visual cortex conscious processing of sights. Spinal cord pathway for neural fibers traveling to and from brain; controls simple reflexes. Cerebral cortex ultimate control and information-processing center. Myelination the process by which axons become coated with myelin, a fatty substance that speeds the transmission of nerve impulses from neuron to neuron. Corpus callosum a long, thick band of nerve fibers that connects the left and right hemispheres of the brain and allows communication between them.
