Examples of light-elicited changes in spike activity for conditioned animals and pseudorandom controls. (A) Light-elicited decrease in the spike activity recorded in pedal neuron VP1 from a conditioned animal. (B) Light-elicited increase in the spike activity recorded in VP1 from a pseudorandom control. (C) Group data depicting the mean difference in VP1 spike activity evoked in 5 min of light and a 5-min period in the dark immediately preceding light onset collected from conditioned animals ((n = 10) and pseudorandom controls (n = 9; *P < .05).
