 **receptive fields:** in terms of the visual system, the receptive field for a visual neuron is the area of the visual field to which a particular neuron responds. Thus, if a receptive field expands, more visual information is being processed by that cell, and if the receptive field shrinks, the cell is responding to a smaller portion of the visual field. Receptive fields exist in cells of all different modalities **receptive fields:** in terms of the visual system, the receptive field for a visual neuron is the area of the visual field to which a particular neuron responds.

 **topographical representation:​** a representation which is characterized by differentiated locations in space. This does not necessarily refer to the topographical nature of the stimulus, but rather the way in which the stimulus is represented in different brain regions  ​ **topographical representation:​** a representation which is characterized by differentiated locations in space.
