Using active conductances results in really exquisite sensitivity to
input levels. A 3 mV increase in the spiking threshold (from -55 to -58
mV) results in the granule cells going from quiet to madly overshooting.
The periglomerular cells and tufted/mitral cells appear to go mildly
chaotic at the same time.
