Additional analysis of LMAN activity. (A) Burst firing of LMAN neurons was less frequent in mHTT birds [fraction of ISIs <5 ms: t(12) = 2.527, P = 0.027]. Burst firing tended to be less frequent even if we restricted our analysis to the number of bursts per second [control: 7.50 ± 1.48 bursts per second, mHTT-Q94: 3.77 ± 0.20 bursts per second; t(12) = 2.126, P = 0.055]. (B) Mean duration of LMAN bursts was shorter in mHTT birds [t(12) = 2.505, P = 0.028]. (C) Trial-to-trial correlation of LMAN activity was not different between control and mHTT birds [t(12) = 1.331, P = 0.208]. (D) CV of mean FR of LMAN activity was not different between control and mHTT birds [t(12) = 1.650, P = 0.127]. Error bars indicate SEM. *P < 0.050.
