(a) VGLUT1 immunochemistry revealed labeled terminals (t-VGluT1) in the tree shrew VPMP that were often seen synapsing (orange asterisk) on medium or small caliber dendrites (d) that also receive other labeled inputs and other small terminals (t; black asterisk). (b) Cholinergic terminals (t-ChAT) also make synapses (purple asterisk) onto small or medium sized dendrites (d). (c) The size distribution histogram of VGluT1 labeled terminals in the tree shrew VPMP. (d) The size distribution histogram of ChAT labeled terminals in the tree shrew VPMP. (e, f) Terminal size distribution (E) and cumulative probability (F) of VGluT2 (green), VGluT1 (orange), and ChAT (purple) labeled terminals in the tree shrew VPMP compare the distinct size characteristics of each terminal type. Scale bars = 200 nm; mit: mitochondria; mye: myelin sheath.
