a Left: relationship between NAc firing rates in familiar environment and restraint, with line of equality for reference. Right: summary of data from left panel. Restraint inhibited overall NAc neuron firing rate (***P < 0.0001 two-tailed signed-rank tests, n = 81 neurons). Data are mean ± s.e.m. b Distribution of NAc neurons excited, inhibited, and unmodulated by restraint. c Left: the spike-phase relationship for example restraint-inhibited NAc neuron. The activity was uniformly distributed across 4 Hz filtered NAc LFP phase angles during familiar environment exploration, but phase-locked during restraint. Center: Relationship between the pairwise phase consistency (PPC) of restraint-inhibited NAc neurons during familiar environment exploration and restraint, with line of equality for reference. Right: summary of data from center panel. Restraint-inhibited NAc neurons increased phase-locking to the 4 Hz filtered NAc LFP during restraint (***P < 0.0001, two-tailed signed-rank test, n = 48 neurons). Data are mean ± s.e.m. d Same as c, but with restraint-excited NAc neurons. Restraint-excited NAc neurons did not increase phase locking to the NAc LFP. (P = 0.33, two-tailed signed-rank test, n = 17 neurons). Data are mean ± s.e.m.
