title: Distribution and characteristics of cholecystokinin-like immunoreactivity in the olfactory bulb of the cat.
abstract: The distribution and characteristics of cholecystokinin (CCK)-like immunoreactive (LIR) nerve fibers was examined in the cat olfactory bulb using immunohistochemistry. CCK-LIR cell bodies were not found; fine varicose CCK-LIR fibers were observed in the most layers. In the main olfactory bulb, no staining was seen in the olfactory nerve layer and white matter. The directions of CCK-LIR fibers in the glomerular, external plexiform and mitral cell layers were generally perpendicular to the bulbar surface; those in the deep granule cell layer were parallel; and those in the internal plexiform and superficial granule cell layers were mixed. In the accessory olfactory bulb, CCK-LIR fibers were localized only in the granule cell layer. The presence of CCK-LIR fibers of the cat olfactory bulb may be involved in the modulation of olfactory transmission.
