Differences in olfactory bulb mitral cell spiking with ortho- and retronasal stimulation revealed by data-driven models

Temporal profile is crucial for larger magnitude filters.
A) Different combinations of input rates (left) including slower increase and decay (retro-like) and faster increase and decay (ortho-like) as well as high and low amplitude as labelled. Two different input correlations (right), with high correlation in gray, and lower correlation in black. B) Resulting linear filters k(t) have consistently larger absolute values when temporal profile of ORN inputs is slower (retro-like), compared to faster (ortho-like).
