  • F2-a Mean ± SEM values (withn in parentheses) for Nb+/GAD+ and Nb+/GAD− cell groups and subgroups. GAD− groups or subgroups were compared with homologous GAD+ cell groups or subgroups by ANOVA, and a significant difference was indicated by the specific symbol of the GAD+ group (shown in the first column) with which the comparison was made (with one symbol =p < 0.05).

  • F2-b Large diameter of cell soma.

  • F2-c Spike width measured from initial positive inflection to first zero crossing.

  • F2-d Latency to antidromically activated spikes from prefrontal cortex.
