Table 4.

Coding fraction of number of spikes (sn), time window (tw) and time to first spike (ttfs) was relatively small demonstrating a remarkable redundancy in the parameter space.

	sn	tw	ttfs
CTRL	0.123	0.144	0.192
α1OFF	0.128	0.165	0.211
α6OFF	0.121	0.181	0.233

Once inhibition was removed by blocking α1 and α6 subunit-containing receptors, the coding fraction increased for time window and time to first spike, but not apparently so for the number of spikes, indicating a preferential control of inhibition over spike patterning and timing rather than on spike number per se.
