Why are barn owls a model system for sound localization?
In 1971, Roger Payne published the paper ‘Acoustic Location of Prey by Barn Owls (Tyto alba)’. Payne had conducted the underlying experiments at Cornell University in partial fulfilment of the requirements for his PhD, which he obtained in 1961. When the paper was published, Payne, a zoologist, was a professor at Rockefeller University. By that time he was already famous for his discovery of so...
متن کاملSound localization by barn owls in a simulated echoic environment.
We examined the accuracy and precision with which the barn owl (Tyto alba) turns its head toward sound sources under conditions that evoke the precedence effect (PE) in humans. Stimuli consisted of 25-ms noise bursts emitted from two sources, separated horizontally by 40 degrees, and temporally by 3-50 ms. At delays from 3 to 10 ms, head turns were always directed at the leading source, and wer...
متن کاملVision calibrates sound localization in developing barn owls.
This study demonstrates that continuous exposure of baby barn owls to a displaced visual field causes a shift in sound localization in the direction of the visual displacement. This implies an innate dominance of vision over audition in the development and maintenance of sound localization. Twelve owls were raised from the first day of eye opening wearing binocular prisms that displaced the vis...
متن کاملSpatial attention modulates sound localization in barn owls.
Attentional influence on sound-localization behavior of barn owls was investigated in a cross-modal spatial cuing paradigm. After being cued to the most probable target side with a visual cuing stimulus, owls localized upcoming auditory target stimuli with a head turn toward the position of the sound source. In 80% of the trials, cuing stimuli pointed toward the side of the upcoming target stim...
متن کاملOptimal models of sound localization by barn owls
Sound localization by barn owls is commonly modeled as a matching procedure where localization cues derived from auditory inputs are compared to stored templates. While the matching models can explain properties of neural responses, no model explains how the owl resolves spatial ambiguity in the localization cues to produce accurate localization for sources near the center of gaze. Here, I exam...
