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.
