Passive membrane properties of interneurons classed by spike frequency adaptation

  • In this table, the passive membrane properties of resting membrane potential (RMP), input resistance (R N), membrane time constant (τ0), equalizing constant (τ1), and electrotonic length calculated from τ0 and τ1 (L) are compiled for the interneurons in the three classes of spike frequency adaptation and for the sample of granule cells. No significant differences were found in these parameters between the normally adapting, nonadapting, and strongly adapting interneurons. 1The RMP of the granule cells was significantly greater than all classes of interneurons (p < 0.01). 2The L values of the nonadapting and strongly adapting cells were greater than theL values of granule cells (p < 0.05).
