Statistical analysis of the whole-brain distribution of monosynaptic inputs to rostromedial tegmental area (RMTg) γ-aminobutyric acid-releasing (GABAergic) neurons in vesicular GABA transporter (VGAT)-Cre mice. The average proportion of dsRed-labeled neurons in each of the ipsilateral and contralateral brain regions with more than 0.1% of the total inputs to RMTg GABAergic neurons (n = 4). Brain areas are grouped into 11 structures. Left, contralateral inputs. Right, ipsilateral inputs.
