AOBmi (Accessory olfactory bulb, mitral layer) synapses onto AOBgr (Accessory olfactory bulb, granular layer)

Electron microscopy of the mitral cell layer of the accessory olfactory bulb in adult male mice identified excitatory synapses between mitral and granule cells. Synapses were classified by postsynaptic density thickness and counted in 20 sections per mouse. Cntn6 knockout males had more of these excitatory synapses than wild-type littermates.
