Figure 3.

Morphology of reticuloreticular axons labeled by BDA. (A) Low magnification photomicrograph of a section through the abducens nucleus showing the location of the higher magnification plates in this figure (labeled boxes). Some of the BDA labeled axons displayed close associations with counterstained somata (arrowheads), while others terminated in the neuropil (arrows). The images were taken from the ipsilateral PRF (B,C), contralateral PRF (D,E), ipsilateral MdRF (F) and contralateral MdRF (G). The case shown is the same as illustrated in Figure 2. (Number of 1.0 μm Z axis planes merged: B,C,E = 3, D,F = 1, G = 4).
