PSY 111 Chapter Notes - Chapter 6: Mirror Neuron, Neuroglia, Grey Matter
Document Summary
Neuroscience = study of the body"s electrochemical communication circuitry (aka nervous system) Characteristics complex - billions of nerves integrated - different parts work together. Adaptable/plasticity - evolution, changes in response to the environment, recover after injury. Electrochemical transmission - neurotransmitters and action potentials. Central (cns) = brain and spinal cord. Somatic ns = sensory and motor nerves - muscular activity, you have fire on you . Autonomic ns - internal organs (heart rate, digestion etc) sympathetic ns (fight or flight increased heart rate, sweat) Parasympathetic ns (rest and digest -- helps return your body to homeostasis) Provide support and nutrition to other cells in the. Information processing - communication and computing = allow us to think, use language, learn, flip the marshmallow off your finger . Mirror neurons (in primates) - imitation and social perception - important in learning and social interaction, mirror the stance of an interviewer . Cell body = nucleus keeps neuron alive.
