CS-Complex Spikes Correlate with Simple Spike Suppression and Conditioned Eyelid Behavior
The occurrence of CS-complex spikes correlated to that of US-complex spikes between cells (n = 28, r = 0.57, p = 0.0015) and marginally to US-complex spike latency (r = 0.384, p = 0.0437). Among trained cells, mean percentage simple spike suppression was intimately connected to the prevalence of CS-complex spikes (n = 28, r = 0.804, p < 0.0001). Additionally, a between-trial mixed-effects linear regression shows that suppression was on average 19.2% higher in trials with a CS-complex spike compared to those without (p < 0.0001). This translates to 9.2 ms of silence, a boost that could be sufficiently explained by the climbing fiber pause (mean = 16.5 ms).
