Response indicates the incidence of visual responses in the two areas. Excitatory and Inhibitoryindicate the incidence of excitatory and inhibitory visual responses.Selective indicates stimulus-selective visual responses.Delay activity indicates sample-selective delay activity.Enhancement and Suppression indicate match–nonmatch effects. The p-values below each column are the results of χ2 tests on the significance of the differences between PF and IT cortices.
