From figure legend of Supplementary Figure 1 : Selective impairments in GABAergic transmission in L5-PNs of TDP mice.
resting membrane potential (mV) action potential threshold (mV) input resistance (Mohm)
WT (n = 29) –62.5 ± 1.6 –40 ± 0.9 92.6 ± 5.0
TDP (n = 25) –61.6 ± 1.0 –41.6 ± 1.3 92.1 ± 4.7
: (e) Intrinsic membrane properties of L5-PNs in M1 of TDP mice were not different from WT mice, including resting membrane potential (WT, –62.5 ± 1.6 mV; TDP, –61.6 ± 1.0 mV; Mann-Whitney U-test, p = 0.65, z(52) = 0.39), action potential (AP) threshold (WT, –40 ± 0.9 mV; TDP, –41.6 ± 1.3 mV, Mann-Whitney U-test, p = 0.53, z(52) = 0.66), and input resistance (WT, 92.6 ± 5.0 MΩ; TDP, 92.1 ± 4.7 MΩ, Mann-Whitney U-test, p = 0.96, z(52) = 0.05). Recordings are from 3 TDP mice (n = 29 neurons) and 3 WT mice (n = 25 neurons). Data are presented as mean ± s.e.m. *, p 0.05. Data are from 20-22 day old mice.
