Neural bases of song preferences in female zebra finches (Taeniopygia guttata)

WE examined the neural bases of song preferences in female zebra finches Taeniopygia guttat a). Females performed more courtship displays in response to conspecific songs than to heterospecific songs. Following electrolytic lesion to the HVc (sometimes referred to as high vocal center), females maintained normal song preferences. However, following lesion to cHV (caudal hyperstriatum ventrale, an auditory area) females performed courtship displays at high rates in response to both conspecific and heterospecific song. Thus cHV, but not HVc, must be intact for female zebra finches to exhibit normal song preferences. Differences between this study and those showing HVc lesions disrupting song preferences in female canaries Serinus canari a indicate interspecific variation in the function of HVc in female songbirds.
