Figure S1. Schematic model of ET-ET and ET-PG-ET cell interactions. ET cells (right) exhibit synchronous spike bursting activity because they are connected by gap junctions (oval). ET cells (left) are synchronized further by synchronous EPSPs from the same olfactory nerve (ON) axons, and by correlated bursts of IPSPs from the same and different sets of periglomerular (PG) cells. The EPSPs and IPSPs occur in sequence and they respectively trigger and subsequently terminate the bursting. Mitral and tufted (M/T) cells may also be synchronized by similar interactions with ET and PG cells (question marks). Short axon (SA) cells have dendrites and axons extending throughout several glomeruli and thus might serve for inter-glomerular inhibition.
