Case pg159, fig2. Soma notes A large centrally-located (WGA-HRP) inj with a central zone that extended across all collicular lvls. Slight invasion of intermed blue/white zone of PPT, NOT & dorlat PAG. Same main features in 5 other large & some similarities with small injs. Terminal notes There was a well defined area of moderate intensity label in the caudomedial part of the inferior olive, centered on the dorsal cap of Kooy, thought to be due to PRT involvement in inj site].

Case pg162, fig5,6. Soma notes Injection site --WGA-HRP- centred on the lateral part of the intermediate white layer. Intermediate blue-white zone extended across all collicular layers and encroached slighlty onto underlying tegmentum. Terminal notes Fibres leave the predorsal bundle ventrally to enter the inferior olive were there is a patch of intense terminal label in its caudal part, probably corresponding to the caudal part of the medial accessory olive contra..
