To examine neuroanatomical mechanisms underlying fine motor control of the primate hand, adult rhesus monkeys underwent injections of biotinylated dextran amine (BDA) into the right motor cortex. Spinal axonal anatomy was examined using detailed serial-section reconstruction and modified stereological quantification. Eighty-seven percent of corticospinal tract (CST) axons decussated in the medullary pyramids and descended through the contralateral dorsolateral tract of the spinal cord. Eleven… CONTINUE READING
