Effect of representational borders on responses of supragranular neurons in rat somatosensory cortex.
In this paper we study the responses of small populations of neurons in layer II/III near the forepaw/lower jaw border in rat somatosensory cortex, comparing cross border (CB) stimuli to non-cross border stimuli (NCB). We found the excitatory component of the population response to CB stimuli was significantly less than the response to NCB stimuli. Thus, at the representational border there are significant changes in the population response of the horizontal circuitry.
