Identification of MCs according to morphological and electrophysiological characteristics.
(a) Photograph of two typical pyramidal MCs obtained from the MC layer of a (P24) rat. (b) Schematic MC recording configuration showing synaptic connections with OSN, PG, and GC. (c) MCs exhibited spontaneous firing with repeated bursts separated by short or long pauses. Recordings were made under cell-attached conditions.
