Figure 3.

Intrinsic excitability is not altered by Controlled cortical impact (CCI). (A) Current‐clamp recordings in response to intracellular current steps (−150 pA to 250 pA, 1 second) in pyramidal neurons from control or CCI‐injured animals. Note the similarity in the intrinsic cellular response. (B) Bar charts of average response values of various intrinsic membrane properties from control (n = 23) and CCI (n = 35). No statistical difference was found for input resistance (P = 0.76), resting membrane potential (P = 0.92), accommodation index (P = 0.23) or firing frequency.
