Not illustrated. 1908 edition. Excerpt: ... CHAPTER IV The Sensori-motor Arcs of the Intermediate Level The afferent or sensory paths, besides taking part in the formation of the reflex arcs of the spinal level, are prolonged upwards to the cerebral hemispheres. Thus many of the axons of the posterior root of each of the spinal nerves, after giving off collaterals to the grey matter of the various segments of the cord, make junctions at the upper part of the cord with other long neurones which, crossing the median line, pass up through the basal ganglia and the central white core of the cerebrum to reach the cortex of the cerebral hemisphere. Each cerebral hemisphere is thus connected by afferent paths with the sense-organs of all parts of the opposite side of the body. And the nerves of the special senses are similarly connected with the cortex. Thus the fibres of the optic nerves contribute to the formation of reflex arcs of the first level by junctions, in the basal ganglia of the brain, with the motor systems that innervate the muscles of the eyeballs, and in the same region make junctions with neurones whose axons pass up from the basal ganglia to the occipital cortex, constituting the principal fibres of that part of the central white matter of the cerebral hemisphere known as the optic radiation. In this way the sensory neurones of _all parts of the body are connected with the cerebral cortex, and those of each of the principal senses are connected with a certain region of the 43 cortex of each hemisphere. These parts of the cortex, known as the sensory areas, are indicated in the Fig. 3 (p. 22) by dotting. We see there the visual area at the posterior or occipital pole of the hemisphere, the auditory area in the temporal lobe, the tactile and olfactory areas on the mesial...
