Fig. 8. A CabTRP Ia-immunoreactive axon bundle projects through the poc and medial aspect of the anterior coc_TG to form terminal arborizations in the CoG. (A) CabTRP Ia immunoreactivity (CabTRP Ia-IR) occurred in a tightly associated axon bundle in the medial aspect of the coc_TG (arrowhead) that terminated as a dense arborization in the antero-medial CoG. There was also more diffuse CabTRP Ia-IR throughout the CoG neuropil and in a subset of CoG neuronal somata. Asterisk indicates area examined to determine the number of CabTRP Ia-IR fibers present in the coc_TG (see text). (B) The CabTRP Ia-lR axon bundle in the medial aspect of the coc_TG (filled arrowhead) projected past the poc towards the TG, and also projected through the poc (open arrowhead). Asterisk indicates area examined to determine the number of CabTRP Ia-IR fibers present in the poc (see text). (C) CabTRP Ia-IR bundle was transected in a preparation in which the medial coc_TG was transected (arrowhead). (D) CabTRP Ia-IR bundle was not transected in a preparation in which the lateral coc_TG was transected (arrowhead). Spatial axes in C are for A–C. All scale bars, 150 µm.
