Early life exposure to noise alters the representation of auditory localization cues in the auditory space map of the barn owl.
The auditory space map in the optic tectum (OT) (also known as superior colliculus in mammals) relies on the tuning of neurons to auditory localization cues that correspond to specific sound source locations. This study investigates the effects of early auditory experiences on the neural representation of binaural auditory localization cues. Young barn owls were raised in continuous omnidirecti...
متن کاملA Dominance Hierarchy of Auditory Spatial Cues in Barn Owls
BACKGROUND Barn owls integrate spatial information across frequency channels to localize sounds in space. METHODOLOGY/PRINCIPAL FINDINGS We presented barn owls with synchronous sounds that contained different bands of frequencies (3-5 kHz and 7-9 kHz) from different locations in space. When the owls were confronted with the conflicting localization cues from two synchronous sounds of equal le...

417 Human auditory localization is remarkably accurate, even in complete darkness under open-loop conditions1–4 (Fig. 2; see also Methods). This performance may rival that of the barn owl, a well studied nocturnal hunter that relies heavily on its auditory system to capture prey. Yet, quite different localization mechanisms are used by each species. In barn owls, sound azimuth (horizontal direc...
متن کاملNon-auditory Effects Caused by Environmental Noise Pollution
Noise pollution is one of the prominent environmental problems affecting human health especially in developing countries. The impacts of noise on health should not be underestimated. Exposure to acoustical stimuli impairs not only the function of auditory system but also that of many other systems of human body. Previous investigations revealed that noise exposure could result in sleep disturba...
متن کاملRepresentation of sound localization cues in the auditory thalamus of the barn owl.
Barn owls can localize a sound source using either the map of auditory space contained in the optic tectum or the auditory forebrain. The auditory thalamus, nucleus ovoidalis (N.Ov), is situated between these two auditory areas, and its inactivation precludes the use of the auditory forebrain for sound localization. We examined the sources of inputs to the N.Ov as well as their patterns of term...
