A: A small-caliber CaMK+ dendrite (Cd) receives synaptic inputs from two VAChT+ terminals (Vt, arrows). B: A small-caliber CaMK+ dendrite and its branch (Cd, line) were found, in serial sections, to receive synaptic input from at least six VAChT+ terminals (asterisks). Another CaMK+ dendrite (Cd, lower right) also received several VAChT+ synapses. Scale bars = 0.5 μm.
