Calbindin-containing non-specific thalamocortical projecting neurons in the rat.
Immunoreactivity for calcium binding proteins was used to demonstrate the neurochemical profiles of non-specific thalamocortical neurons located in the ventromedial nucleus, the centrolateral nucleus, and the nucleus reuniens that project to the somatosensory cortex in the adult rat. Cortical injections of fluorescent tracers combined with immunohistochemistry for calcium binding proteins revealed that retrogradely labeled neurons in these three thalamic nuclei are immunoreactive for calbindin. The present results suggest the presence of a chemically distinct non-specific thalamocortical system which terminates in the neocortex.
