FIG. 7.

A PT and NPT cell recorded on the same electrode with a central trough in the correlogram. Although the cell's response properties are reciprocal in flexion, they are similar in extension, producing a small positive response similarity. The putative synaptic relationship accounting for this correlogram is shown in the bottom left. The dotted interneuron (not recorded) receives common input with cell 102-2a and, in turn, serially inhibits cell 102-2b.
