Percentage of neurons with similar tuning function shapes between single-source and interferer conditions

	Highly Similar Shape		Similar Shape
Interferer Location	Low BF	High BF	Low BF	High BF
Contralateral	57	26	71	43
Central	79	37	93	80
Ipsilateral	71	43	71	67

Values are percentages of neurons that, in the presence of an interferer, have tuning functions that are both sensitive to target azimuth (F test, P < 0.001) and that are highly similar (r² > 0.8, positive r) or somewhat similar (r² > 0.5, positive r) between single-source and interferer conditions. Neurons are grouped according to low-frequency (BF ≤ 1.5 kHz; n = 14) or high-frequency (BF > 1.5 kHz; n = 46) tuning, where BF is best frequency.
