Multiunit mapping techniques were used to examine the representation of the specialized receptor surface of the claw in the Anterior Wulst. 
The results show that a sparse and diffuse projection to the red nucleus arises from deep regions of the hyperstriatum accessorium (HA) of the Anterior Wulst, and that a much more dense projection arises from the caudal part of the nucleus principalis precommissuralis and the medial part of the medial spiriform nucleus (SpMm). These last two sources were themselves shown to receive a substantial projection from HA of the Anterior Wulst.
Combined injections of FB and RITC revealed a topographic projection from the DIVA to the Anterior Wulst.(ABSTRACT TRUNCATED AT 400 WORDS).
