Mitral and tufted cells in the olfactory bulb project their axons to the olfactory cortex, the site thought to integrate the signals from distinct glomeruli. The olfactory signals processed in the olfactory cortex are sent to a variety of higher centers of the brain, which include insular cortex, orbitofrontal cortex, amygdale, hippocampus, and the nucleus accumbens.205...

Different from mammals, in which the mitral cells send axons from the OB to the olfactory cortex through a single tract (the lateral olfactory tract, LOT), there are two major bundles in the secondary olfactory pathways of fish the LOT and the medial olfactory tract (MOT). From the results of neuroanatomical, electrophysiological, and behavioral experiments in cod, goldfish, and carp (Doving and Selset 1980 Stacey and Kyle 1983 Kyle et al. 1987 Sorensen et al. 1991 Hamdani et al. 2000, 2001a, b, 2002 Hamdani and Doving 2003, 2006 Weltzien et al. 2003), the...

The basic circuitry of the MOB. Axons of ORNs travel in the ONL and synapse in the GL on the dendrites of mitrai ceiis (MC), tufted ceiis (externai tufted ceii, ET middie tufted ceii, MT), and generic juxtagiomeruiar (JG) neurons, which include perigiomeruiar ceiis (PG), ET ceiis, and short axon ceiis (SA). SA ceiis interconnect different giomeruii. There are serial and reciprocal synapses between the apicai dendrites of mitral/tufted cells and the processes of JG neurons. Superficial tufted cells (ST) are located in the superficial EPL or at the GL-EPL border. The lateral dendrites of mitral/tufted cells form serial and reciprocal synapses with the apical dendrites of granule cells (GC) in the EPL. GCs are located in the GCL and the MCL. The axons of mitral/tufted cells project locally to GCs (not shown) and also to primary olfactory cortex via the lateral olfactory tract (LOT). The bulb also contains other populations of interneurons neurons, including the van Gehuchten cells (VG) within the EPL... 

Major connections of the main olfactory system. Axons of MOB mitral/tufted cells (circles in the EPL and MCL, respectively) project as the LOT to synapse in a number of structures collectively referred to as primary olfactory cortex (POC). Centrifugal inputs to MOB include feedback projections from POC as well as inputs from subcortical forebrain and brainstem neuromodulatory cell groups.
