DEFINITIONS

RECEPTIVE FIELD: the spatial region where application of a stimulus causes a sensory neuron to respond

  • receptive fields can overlap
  • definition applies to higher order neurons, as well as to receptors and primary afferents
    • size/shape/properties vary among individual cells, especially as you go between cells in a pathway (i.e., the receptive fields of 2nd order neurons will be significantly different from the receptors)

SENSORY UNIT: a primary afferent and the receptors that define its receptive field
