Fig. 5. — Stimulus-evoked neural activity switched from signaling press in DS-sucrose to withhold in extinction. (A) RS-evoked neural activity of all recorded neurons sorted by whether RS presentation resulted in a lever press (lighter colors) or withhold (darker colors) during DS-sucrose and extinction. (B) NS-evoked neural activity of all recorded neurons sorted as in A and C. Neurons in PL and IL neurons that were significantly excited by RS presentation were more excited for pressing than for withholding during DS-sucrose, and were more excited for withheld presses than elicited presses during extinction. (D) Neurons that were significantly inhibited by RSs were more inhibited for pressing than withholding presses during DS-sucrose, and also more inhibited for withholding than for pressing during extinction. Transitions from neural representation of press to withhold were highly significant. Statistics are provided in Neurons in PL and IL Switched from Signaling Press During Sucrose-Seeking to Withhold During Extinction.
