Sensor sensibility: Divergent measurements of dopaminergic signaling to acute morphine administration via fiber photometry

Rachel M Donka, Maxine K. Loh, Mitchell F. Roitman, Jamie D. Roitman

This study uses fiber photometry to compare dopamine signaling responses in the ventral tegmental area and nucleus accumbens to morphine treatment, finding increased activity in some sensors and suppression in others.

Dopamine activity encodes the changing valence of the same stimulus in conditioned taste aversion paradigms

Maxine K. Loh, Samantha J. Hurh, Paula Bazzino…·Mitchell F. Roitman

This study shows that dopamine activity in the mesolimbic system encodes the changing valence of sucrose in conditioned taste aversion, aligning with behavioral responses.
