About centre-surround antagonism
Centre-surround antagonism refers to the way retinal neurons organize their receptive fields.
- Centre-surround antagonism refers to the way that light striking the human retina is processed by groups of light-sensitive cone cells.
- The centre component is primed to measure the sum-total of signals received from a small number of cone cells directly connected to a bipolar cell.
- The surround component is primed to measure the sum of signals received from a much larger number of cones around the centre point.
- The two signals are then compared to find the degree to which they disagree.
