Abstract
The sources of the spinoreticular and spinothalamic fiber systems in the cat brain were studied by the axon transport of horseradish peroxidase (HP) method. In the upper segments of the spinal cord extensive regions of localization of HP-labeled neurons forming direct connections with the reticular formation and thalamus were found. In the lower segments these regions were confined to the medial part of the ventral horn and the intermediate zone of gray matter. Neurons of these regions send direct connections to the contralateral nuclei of the reticular formation and the ipsilateral and contralateral nuclei of the thalamus. The possible pathways of conduction of somatic and pain sensation are discussed.
