TABLE 1.

Number of individual animals with significant effects of time window or stimulus configuration on activation width

Acoustic stimulation	Time window: onset > sustained	Stimulus configuration: monopolar > acoustic
Guinea pigs	3/3	0/3
Cats	2/2	0/1^a

Electrical stimulation	Onset > sustained	Monopolar > bipolar
Guinea pigs	3/3	1/3^b
Cats	7/7	0/7

Fractions reported are the numbers of individual animals with significant effects of time window (onset activation widths greater than sustained activation widths) or stimulus configuration (monopolar activation widths greater than acoustic or bipolar activation widths). Comparisons of stimulus configurations were made for levels that produced equal peak spike rates. For these comparisons, activation width measurements in individual animals were pooled across stimulus frequencies/channels. One of the eight cats (K329) was not tested individually because it had only one valid stimulus channel. The significance criterion was set at p < 0.05

^aThis comparison could only be made in one of the two cats

^bIn one guinea pig where monopolar activation widths were significantly greater than bipolar activation widths (gp147), they were only greater for the onset time window and not for the sustained time window (significant interaction between time window and stimulus configuration in this animal)
