Spatial event plots (SEPs). SEPs reconstructed from a slowly adapting type 1 (SA1) afferent (top), a rapidly adapting (RA) afferent (middle), and a neuron in area 3b (bottom). While the spatial pattern of afferent activation reflects the spatial configuration of the stimulus, cortical neurons respond to specific stimulus features (adapted from Phillips et al. 1988).
