Fig 2. Anterograde projections of NtsLH neurons.
(A) AAV-ChR2 injection site represented by mCherry-labeled (brown) neurons in the LH. (B-G) mCherry-labeled terminals in the target regions. Scale bar = 200 μm. ac, anterior commissure; Aq, cerebral aqueduct; BNST, bed nucleus of stria terminalis; LC, locus coeruleus; LH, lateral hypothalamus; Nts, neurotensin; OC, optic chiasm; PB, parabrachial nucleus; PPy, parapyramidal region; RPa, raphe pallidus; SI, substantia innominata; vlPAG, ventrolateral periaqueductal gray; VLPO, ventrolateral preoptic area; VTA, ventral tegmental area; 3V, third ventricle; 4V, fourth ventricle.
