BEHAVIORAL NEUROSCIENCE FINAL What is neuroscience? How do we study the relationships between behavior and the brain?  Somatic interventions o Manipulating the brain and body directly.  Behavioral interventions o Manipulate behavior to see how it affects the brain.  Correlational studies o Measure two different variables; somatic or behavioral. Cells of the nervous system,  Neurons o Parts of a neuron o How does a neuron’s form match its function?  Spinal motor neurons  Pyramidal cells  Apical dendrite – lots in the hippocampus  Shape can change through learning and memory  Purkinje cells  Located in the cerebellum  Dendritic arbors – can receive lots of signals  Glia  Microglia o Eat foreign materials.  Astrocytes o Large glia cells, 1) help to form the blood brain barrier by connecting to blood vessels, removing nutrients and transferring them to neurons. 2) provide support matrix. 3) neurocommunication  Myelinating glia o Schwann cells  Peripheral nervous system  Myelinate a single location o Oligodendrocytes  Central nervous system  Can myelinate multiple neurons at once Neuroanatomy,  Directions in neuroanatomy. o Dissection planes  CNS vs. PNS o CNS contains brain and spinal cord – PNS is everything else.  Spinal Nerves o Spinal pathways  Dorsal root  Contains sensory neurons  Ventral root  Efferent motor neurons  Cranial nerves o Origin and function Peripheral nervous system  Somatic o What kid of muscle?  Striated or skeletal muscle.  Autonomic o What kind of muscle?  Smooth muscle. o Two major subcomponents,  Sympathetic  Parasympathetic Central nervous system  Four lobes of the brain, o What are the landmarks that divide them?  Five major divisions of the human brain o What are they? o Why are they organized in this way?  How is the brain protected? o Ventricles o Meninges Neurophysiology  Resting membrane potential o What ions are involved?  Potassium / chloride o What forces are involved?  Resting potential chart
