From: Modulation of cue-induced firing of ventral tegmental area dopamine neurons by leptin and ghrelin
Electrophysiological recordings in the rat midbrain. (a) Significant cue-induced neuronal firing in dopamine (DA)-, but not in non-DA (nDA) neurons under food-restriction conditions (resp. green and blue trace). The insert shows a significant difference between both neuron types after cue presentation (first 100 ms). (b) Neuronal activity in response to presentation fruit- and bacon-flavored rewards in putative dopamine (green) and non-dopamine neurons (blue), 300–400 ms after cue onset. All data represented as normalized z-scores. *Significant difference at P<0.05. Shaded gray area represents the reward-delivery interval.
