Early levels of the auditory pathways are tonotopic.⇒
Visual capture is weaker for stimuli in the periphery where visual localization is less reliable relative to auditor localization than at the center of the visual field.⇒
Horizontal localizations are population-coded in the central nucleus of the mustache bat inferior colliculus.⇒
Rucci et al.'s plots of ICc activation look very similar to Jorge's IPD matrices.⇒
Localization of audiovisual targets is usually determined more by the location of the visual sub-target than on that of the auditory sub-target.
Especially in situations where visual stimuli are seen clearly and thus localized very easily, this can lead to the so-called ventriloquism effect (aka `visual capture') in which a sound source seems to be localized at the location of the visual target although it is in fact a few degrees away from it. ⇒
Magosso et al. present a recurrent ANN model which replicates the ventriloquism effect and the ventriloquism aftereffect.⇒
It's easier to separate a target sound from a blanket of background noise if target sound and background noise have different ITDs.⇒
Mühling et al. present an audio-visual video concept detection system. Their system extracts visual and auditory bags of words from video data. Visual words are based on SIFT features, auditory words are formed by applying the K-Means algorithm to a Mel-Frequency Cepstral Coefficients analysis of the auditory data. Support vector machines are used for classification.⇒
Task-irrelevant auditory cues have been found to enhance reaction times in others. visual cues, however, which cued visual localization, did not cue auditory localization.⇒
Fixating some point in space enhances spoken language understanding if the words come from that point in space. Fixating a visual stream showing lips consistent with the utterances, this effect is strongest, but it also works if the visual display is random. The effect is also enhanced if fixation is combined with some form of visual task which is complex enough.
Fixating at some point in space can impede language understanding if the utterance do not emanate from the focus of visual attention and there are auditory distractors which do.⇒
Visual receptive fields in the sc usually consist of an excitatory central region and an inhibitory surround.
(Auditory receptive fields also often seem to show this antagonism.)⇒
Moving eyes, ears, or body changes the receptive field (in external space) in SC neurons wrt. stimuli in the respective modality.⇒
The ventriloquism aftereffect occurs when an auditory stimulus is initially presented together with a visual stimulus with a certain spatial offset.
The auditory stimulus is typically localized by subjects at the same position as the visual stimulus, and this mis-localization prevails even after the visual stimulus disappears.⇒
