aThe position of subnuclei within the lateral habenular complex is indicated in the outlines. The numbers in parentheses denote the number of recovered neurons within a given subnucleus. N, total number of neurons of a distinct cell type. BST, bursting cells; FC I, fusiform cells of type I; FC II, fusiform cells of type II; LHb, lateral habenular complex; LHbLB, basal part of the lateral division of the lateral habenular complex; LHbLO, oval part of the lateral division of the lateral habenular complex; LHbLMc; magnocellular part of the lateral division of the lateral habenular complex; LHbLPc, parvocellular part of the lateral division of the lateral habenular complex; LHbMA, anterior part of the medial division of the lateral habenular complex; LHbMC, central part of the medial division of the lateral habenular complex; LHbMPc, parvocellular part of the medial division of the lateral habenular complex; NGC, neuroglialform cells; PC, polymorphic cells; SC, spherical cells; SIL, silent cells; TR, tonic regular-spiking cells; TIR, tonic irregular-spiking cells; VC, vertical cells.
