BIOL 4340 will present and discuss the normal structure and function of neurons, the functional units of the nervous system. This will include details on resting membrane potentials, action potentials and other aspects of bioelectricity. The structure and neurochemistry of synapses will also be described including information relevant to "new" neurotransmitters. The structure and function of the brain and spinal cord will also be discussed in detail including specific nerve nuclei and tracts (ascending and descending). Specific topics will include: 1) the structure and function of nerve cells and synapses; 2) bioelectricity, action potentials and nerve impulses; 3) the CSF and the physiology of intracranial pressure; 4) the structure and function of the cerebrum, cerebellum and brain stem, including specific nerve nuclei; 5) the cranial nerves; 6) the spinal cord, ascending and descending pathways; 7) the biochemistry of neurotransmitters and neuropeptides; 8) growth and repair in the nervous system. Completion of BIOL 3350 is recommended.
