Center-surround organization of auditory receptive fields in the owl

EI Knudsen and M Konishi

The spinal receptive fields of specialized auditory units in the midbrain of the barn owl (Tyto abla) contain two functionally antagonistic areas: an excitatory center and an inhibitory surround. The response of these units represents the balance of acoustic activation of the two areas, which in turn depends upon the location, intensity, and spectral content of the sound stimulus.
