Summary of all cell pairs (intersomatic distance < 50 µm) recorded in this study. All recordings made in the presence of AP5. In some experiments DL-2-amino-5-phosphopentanoic acid (AP5) and 6,7-dinitroquinoxaline-2,3-dione (DNQX) were present, so the excitatory connection could not be tested. The expected numbers of reciprocal connections reflect the product of the sampled incidences of connections in each direction.
