The average (SD) for the correlation coefficient between predicted and actual responses and between actual responses and the amplitude envelope of the sound for neurons in MLd classified into the five functional groups

Group®	Prediction	Pop. Pred. (n = 5)	Pop. Pred. (n = 10)	Act versus Env (n = 5)	Act versus Env (n = 10)
NB-T	0.67 (0.12)	0.72 (0.06)	0.78 (0.04)	0.75 (0.06)	0.80 (0.05)
BB(F)	0.54 (0.16)	0.56 (0.08)	0.57 (0.08)	0.58 (0.09)	0.62 (0.08)
BB(S)	0.60 (0.15)	0.66 (0.07)		0.87 (0.02)
WB	0.58 (0.21)	0.68 (0.05)		0.83 (0.02)
2B	0.45 (0.10)

The columns show the predicted and the actual responses for single neurons (Prediction), between the population predictions and the population PSTH for 5 neurons and 10 neurons (Pop. Pred.), and between the population PSTH and the sound amplitude envelope for 5 and 10 neurons (Act vs Env). Before calculating the correlation coefficient, the PSTH is smoothed with an 11 ms Hanning window. The correlation coefficient for single neurons is corrected by the noise in the estimation of the STRF as described by Hsu et al. (2004a). All predictions are estimated with data not used in the estimation of the STRF. Cells with no values correspond to cases in which there were not enough neurons in that category.
