We ran 1000 Monte Carlo simulations with voxel - level p < 0.005,
cluster size > 87, corresponding to a corrected p < 0.05 as determined by AlphaSim correction (Yang et al., 2016; Chen and Mo, 2017).
They are rather composed of filaments (
clusters of odor molecules) of various
sizes (
> mm) and concentrations interspersed with regions of clean air.
