ClaC neurons and PV claustral neurons form frequent unitary synaptic connections within the claustrum. A, Schematic of a paired recording from a retrogradely labeled ClaC neuron and a PV neuron. B, A unitary excitatory synaptic connection between a presynaptic ClaC neuron (green) and a postsynaptic PV neuron (red). C, A unitary inhibitory synaptic connection between a presynaptic PV neuron (red) and a postsynaptic ClaC neuron (green). This recording is from a different pair than that shown in B. D, Summary data showing the probability of connection for ClaC→PV and PV→ClaC connections (ClaC→PV: n = 13 of 38 tested connections; PV→ClaC: n = 11 of 38 tested connections; ClaC→PV: 8 pairs; PV→ClaC: 6 pairs; ClaC↔ PV: 5 pairs; unconnected: 19 pairs).
