Odor space and olfactory processing: Collective algorithms & neural implementation
80 adapting neurons, two sniffs: 100-500 msec has a mixed odor 50*x + 1000*y. At 500 msec 75*x + 1100*y. The sniff at 100 milliseconds strongly activates more than half the neurons, after which they adapt. The changed sniff at 500 milliseconds is almost invisible.
b) as in a), but the y-axis = firing rate at the time of each action potential. The second sniff is now clearly visible, and most spikes appear to belong to one of three patterns. A 20% spread in D was included to produce parameter-spread noise.
