Document Summary

Week 8 psyc: sensation: sensory system gathers info about the environment, perception: process involved in the organization and interpretation of sensations, transduction: conversion of physical energy into electrical potentials --- happens in sensory receptor cells, five senses. Proprioception: the sense of the relative position of limbs and other parts of the body, due to receptors in muscles and joints. Vestibular senses: balance: receptor cells: specialized neuron that convert physical energy into electrical signals, sensory domain has adequate stimulus: type of physical energy which receptor is especially tuned, human can sense: Pattern code: info conveyed in the activity across a whole population a lot of cells. Temporal code: uses rate at which the neurons are firing to determine the perception. Place or labeled-line code: depends on the location of the neurons firing to determine perception: how adaptation works. Spontaneous rate: rate of neuronal firing when no stimulus is present.
