Distinct PSPs evoked by stimulation of converging inputs with different origins. A, PSPs of regular-spiking layer 2/3 neuron in area 17 after stimulation (1.8T) of feedback inputs (FB) and putative thalamocortical inputs entering from subcortical white matter (WM). Note that this neuron, which shows no hyperpolarizing inhibition to FB inputs, exhibits pronounced hyperpolarization (at depolarized membrane potentials) to WM stimulation. B, PSPs of regular-spiking layer 2/3 neuron in area 17 after stimulation (1.6T) of FB inputs and local horizontal connections (Local) within area 17. Note that this neuron, which shows no hyperpolarizing inhibition to FB inputs, exhibits strong hyperpolarizing response (at depolarized membrane potential) to local inputs.
