Figure 2.
Photomicrograph of 5-HT1F receptor immunoreactive vestibular ganglion cells in the macaque. (A) Inferior and (B) superior vestibular ganglion. Note the greater intensity of the immunoreaction in small ganglion cells and the association of immunoreactive fibers with blood vessels. The calibration bars represent 40 microns. Staining patterns and associated cell sizes in representative vestibular ganglion cells; (C,F) large to intermediate sized cells showing punctuate staining associated with the cell membrane. (D,G) Large to intermediate sized cells with demarcated immunoreactive regions at one pole of the cell. (E,H–K) A few intermediate and mainly small sized cells with intense, reasonably homogenous somatic immunoreactivity.
