Intraglomerular gap junctions enhance interglomerular synchrony in a sparsely connected olfactory bulb network

摘要

Key points class="unordered" style="list-style-type:disc" id="tjp12485-list-0001">Despite sparse connectivity, population‐level interactions between mitral cells (MCs) and granule cells (GCs) can generate synchronized oscillations in the rodent olfactory bulb.Intraglomerular gap junctions between MCs at the same glomerulus can greatly enhance synchronized activity of MCs at different glomeruli.The facilitating effect of intraglomerular gap junctions on interglomerular synchrony is through triggering of mutually synchronizing interactions between MCs and GCs.Divergent connections between MCs and GCs make minimal direct contribution to synchronous activity.
