Direct and indirect pathways of CDt circuit. CDt processes visual objects, mainly based on inputs from visual cortical areas. The direct pathway is composed of two serial inhibitory connections: CDt to cdlSNr, cdlSNr-SC. Its function is to choose good objects. The indirect pathway is composed of three serial inhibitory connections: CDt-cvGPe, cvGPe-cdlSNr, cdlSNr-SC. Its function is to reject bad objects. cvGPe: caudal-ventral part of the globus pallidus externus.
