Relationship between LHb neuronal activity and licking. (A and B) Mean responses of indicated neuron type during indicated trial type over sessions before (−3 to −1) and during stress (0–5). (C) Mean change in licking during sucrose presentation, normalized to sessions before stress (n = 4 mice). Sessions as in A and B. (D) Pearson’s correlation coefficients for trial-by-trial correlations between neuronal response and licking percentage during sucrose consumption for indicated neuron type. Black, correlation P < 0.05; gray, not significant. *P < 0.005. Trials with no licking in the first second after sucrose delivery or omission were excluded in A, B, and D (see Materials and Methods).
