The paper shows that dopamine responses decrease rapidly before a hedonic switch during sodium satiation, tracking cumulative sodium intake in rats.

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.

This study identifies cell-type specific activity in the cuneiform and pedunculopontine nuclei of mice during locomotion, non-locomotor behaviors, and sensory stimulation.

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

This study examines how different feeding schedules modulate the locomotor and motor neuron responses to d-amphetamine in zebrafish larvae.

The paper introduces OHRBETS, an open-source platform for head-fixed behavioral experiments in mice, demonstrating operant conditioning and dopamine signaling during reward tasks.

This paper extends homeostatic regulation into a reinforcement learning framework to model sodium-seeking behavior and dopamine signaling in rats.

This study shows that central oxytocin reduces food-seeking behavior and VTA dopamine responses to food cues in male rats, but not postingestive reward value encoding.

This study compares dopamine responses in rats to two sucrose delivery methods, finding that predicted pellet cues elicit greater dopamine release than predicted infusion cues.
