Compare and contrast the receptive fields of retinal cells (bipolar and ganglion cells) with cortical receptive fields.

What will be an ideal response?


The arrangement of receptive fields for bipolar and ganglion cells is referred to as an antagonistic center-surround organization. The response of a cell depends on the amount of light falling on its center relative to the amount of light falling on its surround. It is called antagonistic because light falling on the center of the receptive field always has the opposite effect on the cell's activity from light falling on the surround. Retinal cells have doughnut shaped receptive fields that respond best to dots of light. In the cortex, the receptive fields are determined by simple and complex cortical cells. Simple cortical cells are those cells that respond to stimuli shaped like bars or edges that have a particular slant or orientation in a particular location on the retina. Complex cortical cells are cortical cells that share the simple cells' preference for stimulus size and orientation but without reference to the stimulus's location, as long as it appears in the receptive field.
