Multisensory binding - Coggle Diagram

- - - - enhancement of phase locking for short latency GBA for attended multi sensory stimuli
      - another study: participants attended to either visual or auditory stimuli - did not influence GBA - GBA enhancement was observed when both auditory and visual stimuli were presented with close temporal synchrony (0 +/- 25 ms) -> Senkowski (2007)
      - alpha band activity when attention to visual stimuli was suppressed in favour for attention to auditory ? - not very clear evidence yet
    - - audiovisual processing in cross modal object recognition / matching - larger GBA for semantically congruent presentations
      - enhanced GBA in audiovisual symbol-to-sound matching task - when auditory stimuli matched elements of visual pattern compared to nonmatching elements
      - and more...
    - - sound-induced flash illusion (single flash of light is accompanied by pair of rapidly presented auditory stimuli) - often leads to percept of two flashes of light
        
        gamma band activity increase observed in occipital areas for illusory trials (where illusion was induced)
      - McGurk illusion
        
        enhanced GBA when illusion was perceived - topographically comparable to GBA enhancement in auditory mismatch study - perceived auditory pattern change (there is no real pattern change though)
      - cross modal (visual + somatosensory) rubber hand illusion
        
        GBA and phase synchrony occurred in trials with cross modal congruence
    - - increased coherence in lower beta band between temporal and parietal electrode sites during passive viewing of multi sensory stimuli
      - enhanced evoked beta oscillations in cross modal button press task
      - sensory gating paradigm: stronger (auditory and somatosensory) evoked beta responses observed when current and preceding stimulus differed in modality
      - further studies: in addition to beta, also theta. alpha and gamma band are modulated by multi sensory interactions
      - trigger phase resetting by stimulating median nerve in monkey
        
        external somatosensory stimulus synchronises oscillations to auditory stimulus
- - - - synthesised consonant-vowel syllables: ta / pa
    - - videos of male speaker uttering ta / pa
    - - acoustic deviant pa + ta
      - visual deviant ta + pa
      - standard ta + ta
