A small number of exacting studies have used pseudorabies virus, a transneuronal retrograde tracer that crosses functional synapses [32], to specify the multisynaptic relays in the central nervous system that participate directly in regulating the heart.
The gland receives input from the retina via the suprachiasmic nucleus (SCN) in a multisynaptic pathway (Fig 1).
The SCN achieves this in part through a multisynaptic pathway that connects it with the pineal gland and the pineal gland's secretion of melatonin [16-19], a sleep-organizing hormone or chronobiotic [20, 21].
Considering the broad reach of the SCN and the anatomical complexity of its multisynaptic output, it is challenging to delineate the pathways by which the SCN network conveys light information to the rest of the brain and body.
Furthermore, multisynaptic pathways from the SCN have been identified [38, 43].
The SCN regulates melatonin secretion from the pineal gland through a multisynaptic pathway involving the PVN (as reviewed in [111]).
In cerebellum, a mossy fiber (MF) excitatory terminal has hundreds of release sites that establish synaptic contacts with different granule cell dendrites positioned close together forming a multisynaptic arrangement or glomerulus.
This nucleus contains simple oneto-one, mostly axodendritic, synapses but is also enriched in divergent (one axonal terminal innervating several postsynaptic dendrites or spines) and convergent (several axon terminals making clustered synaptic contacts on the same dendritic segment) multisynaptic arrangements or glomeruli.
At the same time, individual synapses in multisynaptic glomeruli in NTS can strongly influence each other thanks to the direct apposition of neighboring synaptic elements mostly devoid of intervening glial processes that generally cover nonshared, outer part of synaptic perimeters.
