Figure 1. Combinations of neurochemically distinct pericellular baskets can target a shared cell soma.

(A) Convergence of TH⁺ and VGLUT3⁺ pericellular baskets has been reported in the lateral septum [2]. (B) 5-HT⁺ and VGLUT3⁺ baskets from separate Pet1 neuron lineages converge on the same targets in the cortex, hippocampus, and septum [14]. (C) Baskets comprised of 5-HT⁺, VGLUT3⁺, and VGLUT3⁺/5-HT⁺ fibers are common in the septum [14]. (D) It remains to be tested whether other combinations of axons known to form pericellular baskets converge on their target neurons.
