synapses, whereby an axon directly synapses at the soma, can lead to direct potential transfer, resulting in effective modulation of the excitability of the postsynaptic neuron.
This could explain why in OB the dendrodendritic connections predominate because most of their interneurons do not have an axon (Crespo et al., 2013; Kato el al., 2013; Nagayama et al.), therefore, the lack of axodendritic or axosomatic
connections between the interneurons and the projection neurons (mitral cells and tufted cells), would make it difficult to transport the virus between the latter and the neighboring interneurons.
They received both symmetrical (inhibitory) and asymmetrical (excitatory) axosomatic
Thus, it has been shown that under conditions that stimulate OXT release, such as parturition and lactation, there is an increase in the numerical density of axosomatic and axodendritic synapses on OXT neurons in the SON as seen in tissue of rats that have nursed their pups for 11 days .

After this, every neuron stained for ORX was evaluated at high magnification (100X, oil immersion lens) to determine if it was contacted by a VIP or VP labeled fiber; only axosomatic
contacts of VIP or VP fibers on ORX neurons were considered.
