The ability to localize sounds is a major evolutionary adaptation that plays an essential role in the survival of many species. As the auditory system does not directly encode spatial information in its sensory epithelium, the brain has a complex task of reconstructing the auditory spatial world. Whereas early research in anesthetized animals has revealed that neurons in the auditory cortex (AC) increase their firing in response to sounds from the contralateral auditory hemifield, there is increasing evidence in awake animals that some neurons are tuned to sounds coming from the midline of the
