What is Tyrosine hydroxylase‐immunoreactive interneurons in the olfactory bulb of the frogs Rana pipiens and Xenopus laevis about?

## Abstract We studied tyrosine hydroxylase (TH)‐immunoreactive neurons and neuropil in the olfactory bulb of the leopard frog, __Rana pipiens__, and in the clawed frog, __Xenopus laevis__. In both frogs, TH processes in the main olfactory bulb showed a trilaminar organization, with a densely stained external glomerular layer (GL), a moderately stained middle mitral cell layer (MCL), and internally a weakly stained internal plexiform layer (IPL) and granule cell layer (GRL). TH‐positive cells in the MCL and IPL could be divided into two types. Type 1 cells had one or two thick dendrites that arborized within glomeruli in the GL and often had a thin “axon‐like” process that exited the cell on the internal surface, with a recurrent collateral that ascended into the GL. Type 2 cells had beaded dendrites arborizing in the MCL and no discernible axons. Both type 1 and type 2 cells were numerous in the MCL and IPL of __Rana__, whereas only type 2 cells were common in the MCL and IPL of __Xenopus__. In the GL, labeled cells were numerous in __Xenopus__ but rare in __Rana__. Mitral cells were stained retrogradely by tracer injection into the lateral olfactory tract and by local injection i
