VIII. Experiments upon the influence of sensory nerves upon movement and nutrition of the limbs. Preliminary communication

In the 14th of the 'Lecons sur la Physiologie et la Pathologie du Système Nerveux,’ Claude Bernard draws attention by experiments on the frog and on puppies to the degree of impairment in movement undergone by a limb that has been rendered insensitive by section of the sensory roots of its spinal nerves. In a series of experiments carried out during the last eighteen months, we have examined the same thing in the monkey, using chieflyMacacus rhesus , and observing the animals for periods up to four months from the time of operation. We propose to give here a brief account of the results obtained.
