Abstract

The organization of the descending projections from the intralaminar parafascicular nucleus was studied using biocytin as an anterograde tracer in rats. After biocytin injection into the lateral parafascicular nucleus, threebundles of fibers descending throughout the brainstem were seen. Terminal fields were found in several structures, for example the lateral geniculatenucleus, nucleus reticularis thalami, subthalamus, zona incerta, substantia nigra, red nucleus, periaqueductal gray, superior colliculus, reticular formation, raphe nuclei, pontine nuclei, trigeminal complex, and ventral horn of the spinal cord. Different types of labeled terminals (small terminal boutons, en passant varicosities, large claw-like terminals) were observed,particularly in the substantia nigra and reticular formation where the density of terminals was highest. The organization of these extensive descending connections to both motor and sensory structures does not allow functions to be conclusively attributed to the parafascicular nucleus neurons. Further investigations are required to resolve this question.
