Figure 3. Acute 4-AP rescues firing precision deficits in SCA684Q/84Q mice.

Figure 3

(A) Acute application of 5 μM 4-AP in cerebellar slices from SCA684Q/84Q and WT mice. (B) Representative traces from SCA684Q/84Q mouse Purkinje cell before (orange, top) and after (red, bottom) 4-AP wash-in. (C) Purkinje cell spiking becomes more regular with the application of 4-AP (CV was reduced after 4-AP application, CVbefore = 0.15 ± 0.02; CVafter = 0.10 ± 0.009; paired Student’s t test, P = 0.0027; N = 11), while (D) not altering firing rate (frequencybefore = 60.7 ± 5.6 Hz; frequencyafter = 61.8 ± 5.6 Hz; P = 0.15). ***P < 0.005.
