Golgi study on neurons and fibers in Nucl. rotundus of the thalamus in chicks.
The structural arrangement of nucleus rotundus was studied by Golgi method. Large, multiangular principal neurons, their dendrites and dendritic terminals were observed. The long dendrites and their side-branches course parallel and/or perpendicular to each-other and they are arranged about in dorso-ventral latero-medial and rostro-caudal directions. The dendrites and their side-branches develop characteristic terminal branchings. These dendritic terminals overlap each-other and the area is called dendritic terminal field. The tecto-rotundal fibers traverse the nucleus in large bundles and the final sections of fibers join to the dendrites of principal neuron and terminate in dendritic terminal fields.
