The solid signal paths represent afferent signal paths associated with the sensory neural system. The dashed lines represent efferent paths associated with the command neural system. Note the two distinct division in the signal bundle coming from each eye. The first division supports stereoptic vision. The second division separates signals from the foveola from the remainder of the optical bundle and directs them to the pretectums for precision processing. The remainder of the bundles are directed to the LGN's and on to area 17 for alarm sensing.
The precision servo signals from the pretectums are passed to the Superior Colliculus for further processing and delivery to both the oculomotor servo system and to the cortex.
Note the entry of signals into the cortex at two distinct points via separate neural paths.
The complete discussion of this figure is found in Section 15.2 of Chapter 15.
