Bidirectional connections between ACC neurons. ( A ) Reciprocal connections between two pyramidal neurons. Left, diagram of the connection. Middle, two successive stimulations (1 ms, 90 mV) in cell 1 (upper) induced inward currents in cell 2 (lower). Original traces are shown in gray and the averaged trace is shown in black. Right, stimulations in cell 2 (lower) induced inward currents in cell 1 (upper). Original traces are shown in grey and the averaged trace is shown in black. ( B ) Diagram and sample traces of reciprocal connections between pyramidal neurons and interneurons. ( C ) Diagram and sample traces of reciprocal connections between two interneurons. ( D ) Diagram and sample traces of electrical coupling between two interneurons. The dashed rectangle is magnified and the latency of stimulation and response is indicated by red dash lines. In the right lower corner, action potentials induced in cell 1 are coupled with inward currents in cell 2.
