The apartment bodies of Thalamus first aferent neurons are located in the dorsal rhizomorph radically ganglia, which lie in the vertebral foramina at each spinal twine level. Each neuron has a unique axon that bifurcates, sending inseparable aim to the peripheral tissues it innervates and the other into the dorsal horn of the spinal rope. Second-order neurons synapse in tha- lamic nuclei with third-order neurons, which in express send projections through the internal capsule Posterior and corona radiata to the postcentral gyrus of the division cerebral cortex (Judge 47 2).
