Fig 13. Extended laser experience alters distribution of strong eaters vs strong self-stimulators.

Fos plume maps showing strong laser-bound eating (> 3 g) and/or strong laser self-administration (> 200 laser spout touches) in ChR2 subjects before (A) and after (B) extended laser exposure, as well as how extended laser exposure altered behaviors in each rat mapped here (C). Scores were obtained by subtracting non-laser from laser results for each experiment type. Map conventions are the same as in prior figures.
