Figure 9.

Schematic drawing of the input and output relations of the caudal dorsal cap of the inferior olive. The excitatory pathway (red arrows) relays the retinal slip signal via the accessory optic system to the climbing fibers that project to the VA zones (F2 and F4) of the flocculus. Recording from one of these zones is indicated by the green trace, which shows an example of SSs and a CS. The inhibitory projection from the PrH to the caudal dorsal cap (blue arrow) is the proposed source of the nonvisual signals carried by the floccular climbing fibers.
