PSYC 367 Study Guide - Comprehensive Final Exam Guide - Hair Cell, Cochlear Nerve, Absolute Threshold
Document Summary
Describe the steps in the perceptual process. List the 3 broad questions to be studied in this course and the techniques available to study each one. List the 7 sensory cranial nerves and show how they illustrate the doctrine of specific nerve energies. Define synapse, neurotransmitter and action potential and describe how neurons communicate with each other. Compare and contrast the 4 neuroimaging techniques for studying human brain function. Physical stimulus physiological response sensory experience. Transduction: how energy in the environment gets transformed into electrical energy by the nervous system. Information processing: what happens to the electrical signals as they travel through the nervous system to the brain. Sensory coding: how the brain understands what the electrical signals reaching it mean. Doctrine of specific nerve energies: the nature of a sensation depends on which nerves are stimulated, not on how the nerves are stimulated. Makes sense b/c neural signals are identical across sensory modalities.
