Dentritic range of the neurons of the intermediate gray at the levels of the first and second lumbar segments of the spinal cord in the cat. 4. The range of dendrites of the lateral horn neurons.

The topography of dendrites of the lateral horn neurons at the level of L1--L2 have been investigated in young and mature cats using Golgi impregnation method. It has been stated that the dendrites of investigated neurons reach the lamina III (dorsally), the lateral funiculi (laterally), and the lateral and central parts of the intermediate gray (medially). They penetrate the thoracic nucleus as well. In their ventral course they were found within the laminae VIII and IX. Afferent connections of the neurons are also discussed.
