Nonclassical receptive field
Nonclassical receptive field Classical receptive fields are plotted by spots of light or moving stimuli. If a cell responds consistently to that stimulus then the location of that stimulus is said to be within the cells classical receptive field. Activity outside that area can influence a cell's response to the original stimulus. Examples : Motion, Color.
