The morphology of GABA-immunoreactive neurons in the accessory olfactory bulb of rats

Brain Res. 1992 Aug 21;588(2):317-23. doi: 10.1016/0006-8993(92)91593-4.


GABA-immunoreactive (IR) neurons were observed in the accessory olfactory bulb (AOB) of adult female rats. Many somata and dendritic trees of periglomerular-located cells were GABA-IR and the size of their somata was variable. Numerous somata and dendrites in the granule cell layer were IR. These results suggest that a large number of the interneurons in the AOB are GABA-IR.
