Intrinsic action potential (AP) properties of intact yellow fluorescent protein (YFP+) pyramidal neurons 2 days postinjury.

AP Property	Sham	mTBI	t25 ratio	p-value
Amplitude (mV)	108 ± 4.5	106 ± 4.4	–0.25	0.8039
Half-width (ms)	0.74 ± 0.040	0.81 ± 0.038	1.30	0.2048
Rise Tau (ms)	0.23 ± 0.115	0.44 ± 0.111	1.34	0.1933
Decay Tau (ms)	6.3 ± 1.03	1.2 ± 0.99	–3.6	0.0014

Data summarized as mean ± SEM. Statistics: multilevel analysis of group and animals with five AP nested in each cell. Sham n = 13 cells from three mice (63 AP, 2 missing) and mTBI n = 14 cells from four mice (70 AP total).
