Abstract:
It has been believed so far that in the mammalian olfactory bulb, only granule cells form reciprocal synapses with mitral/tufted cells in the external plexiform layer (EPL). However, the present electron microscopic study demonstrated for the first time that another group of immunocytochemically defined interneurons different from granule cells, viz., neurons containing a specific calcium-binding protein parvalbumin, also made reciprocal synapses with mitral/tufted cells in the EPL.
