Complex spiking occurs with higher peak rates and greater synchrony when movements are correctly timed. A) Peri-release time histogram of calcium events on correct (black) and early (red) release trials (n=17 animals, 30 sessions, 1146 dendrites). Bin width = 33 ms. Shaded area is ±SEM across dendrites. B) Summary of average event rate for correct and early releases for each session (n=30). Error bars are ±SEM across dendrites. C) Same as B for average event latency relative to release for each session (n=30). Error bars are ±SEM across dendrites. D) Summary of average standard deviation (S.D.) of event times across trials within single dendrites for each session (n=30). Error bars are ±SEM across dendrites. E) Same as D for measurement of S.D. of event times across dendrites for each session (n=30). Open circles are statistically significant for reduced correct trial jitter across dendrites (paired t-test). Error bars are ±SEM across trials. F) Summary of the average S.D. of event times when aligned to either lever release or visual cue for each session (n=30). Error bars are ±SEM across dendrites. G) Summary of the average latency to peak event probability relative to cue (gray circles) or lever release (black circles) compared with the average session reaction time for each session (n=30). X-error bars are ±SEM across trials; Y-error bars are ±SEM across dendrites.
