Abstract

We studied the auditory neurons in the optic tectum of the unanesthetized pigeon, using single-unit recordings and acoustic free-field stimulation. Most units showed spatial tuning, with best areas located in the contralateral hemifield. All units responded also to visual stimuli, the auditory best areas being in rough alignment with visual receptive fields.

      There is evidence of gaze-mediated shifts of auditory spatial receptive fields in superior colliculus (SC) and its avian analog [11–13]. The SC is the principal midbrain nucleus involved in executing saccadic eye movements and is thought to integrate spatial information across modalities [34]. It contains spatially tuned auditory neurons that typically respond to high frequencies and are generally more sensitive to ILDs [35, 36].
