A) Cartwheel cell burst firing is suppressed in CaV3.2−/− animals. Spike trains are color coded to current injection amplitude.
B) Instantaneous frequency of first two spikes in a train was lower in CaV3.2−/− animals. Box plot indicates median, quartiles and 10/90 percentiles. ** p < 0.01, Mann Whitney.
C) Quinpirole did not alter AIS Ca in CaV3.2−/−.
