Population averages as a function of stimulus size and time bin duration

	Stimulus size	Time bin duration (msec)
	Stimulus size	4.6	13.8	25	50
Information per second (bits/sec)	1 × CRF	15.6	10.6	8.4	6.3
	2 × CRF	18.3	13.2^*	10.7^*	7.9^*
	3 × CRF	18.7	13.6^*	11.1^*	8.0^*
	4 × CRF	17.7	13.1	10.2	7.5

Information per spike (bits/spike)	1 × CRF	1.0	0.7	0.5	0.4
	2 × CRF	1.3	0.9^*	0.7^*	0.5^*
	3 × CRF	1.6^*	1.2^*	1.0^*	0.7^*
	4 × CRF	1.6^*	1.2^*	1.0^*	0.7^*

Efficiency (%)	1 × CRF	17.5	16.5	16.8	17.4
	2 × CRF	21.8^*	21.7^*	22.5^*	22.9^*
	3 × CRF	26.0^*	26.1^*	26.9^*	26.6^*
	4 × CRF	26.2^*	26.6^*	26.7^*	26.5^*

Asterisks indicate mean values that significantly exceed 1 × CRF mean values (p ≤ 0.05).
