WebB) When a stimulus touches the surround of the receptive field of Cell E, the firing rate decreases. Note that the stimulus is in the surround of Cell E’s receptive field but is also in the center of Cell D, so the firing rate of Cell D will increase. ‘Touch Receptive Field Surround’ by Casey Henley is licensed under a Creative Commons ...
