Document Summary
How do scientists study the nervous system: until recently, it was difficult, nigh impossible, to study what goes on in the brain without causing damage. There is no degree of strength: to facilitate the transfer of the action potential, many neurons are insulated by myelin, periodically along the length of the axon, there are bare strips that are called nodes of. Ranvier, which exist to expose the cell to the extracellular fluid. How is the nervous system organized: the peripheral nervous system. Involved in recognizing, learning about and responding to stimuli associated with fear: the hippocampus. Important for certain types of learning and memory, specifically episodic memory, or memory regarding events: the striatum, works with the substantia nigra to produce fluid movements, nucleus accumbens. Located in the back of the brain and contains the primary sensory regions that are important for processing basic information about visual stimuli: temporal cortex.
