Figure 5. An interneurone that was postsynaptic to two consecutively recorded pyramidal cells.

A, the axonal arborization was slightly different from the other 7 reconstructed interneurones in that it innervated s. oriens, albeit sparsely, as well as projecting to s. lacunosum-moleculare where it ramified extensively. The axon was reconstructed from four 60 μm thick sections. B and C, the amplitude and duration of the EPSPs differed between the two connections.
