From: Globus pallidus is not independent from striatal direct pathway neurons: an up-to-date review

Summary of the single neuron tracing study for striatofugal and pallidofugal neurons Red and orange lines indicate the projections of direct and indirect pathway neurons, respectively, in the striosome (1st raw) and matrix (2nd raw) compartments. Green and blue lines indicate the projections of prototypic and arkypallidal neurons, respectively. Each numeral is the mean number of the axon varicosities (per neuron) that were seen in the corresponding target region. GP, globus pallidus; EP, entopeduncular nucleus; PPT, pedunculopontine tegmental nucleus; SNc, substantia nigra pars compacta; SNr, substantia nigra pars reticulata
