“…Visual, auditory, tactile, and olfactory inputs are each processed by their respective regions of unimodal sensory cortex (Lyons, Sanabria, Vatakis, & Spence, 2006;Macaluso & Driver, 2005;Martin, 1991 ;Squire & Kandel, 1999). As discussed in detail below, these sensory representations are, then, combined as a result of the mediation of the thalamus and the thalamo-cortical neuronal network circuitry (Llinas, Grace, & Yarom, 1991;Llinas & Ribary, 2001;Singer, 1993;Steriade, Jones, & Llinas, 1990).…”

Recent neuroimaging studies on posttraumatic stress disorder (PTSD) have revealed a consistent decrease in thalamic activity, relative to non-PTSD controls. Empirical studies of the past decade have shown the thalamus to be centrally involved in the integration of perceptual, somatosensory, memorial, and cognitive processes (thalamo-cortical-temporal binding). A theoretical model is proposed to suggest that one underlying mechanism of EMDR stimulation (dual-attention stimulation/bilateral stimulation [DAS/BLS] ) is thalamic activation, specifi cally of the ventrolateral and central-lateral nuclei. It is hypothesized that this may facilitate the repair and integration of somatosensory, memorial, cognitive, frontal lobe and synchronized hemispheric functions that are disrupted in PTSD.

“…The direction of visual stimuli can capture the direction of auditory apparent motion but it has not yet been shown that the direction cues in the auditory stimuli can capture the direction of visual apparent motion Soto-Faraco et al, 2004b;Strybel and Vatakis, 2004). Likewise, the tactile motion distractors have a stronger influence upon the perception of auditory motion direction than auditory motion distractors do on tactile perception (Soto-Faraco et al, 2004a), and the visual motion distractors have a stronger influence on the perception of tactile motion direction than tactile motion distractors do on visual perception (Bensmaïa et al, 2006;Craig, 2006;Lyons et al, 2006). These asymmetries in both spatial and temporal manipulations have been attributed to differences in functional appropriateness and precision between different modalities.…”

Capture of Intermodal Visual/Tactile Apparent Motion by Moving and Static Sound

Apparent motion can occur within a particular modality or between modalities, in which a visual or tactile stimulus at one location is perceived as moving towards the location of the subsequent tactile or visual stimulus. Intramodal apparent motion has been shown to be affected or 'captured' by information from another, task-irrelevant modality, as in spatial or temporal ventriloquism. Here we investigate whether and how intermodal apparent motion is affected by motion direction cues or temporal interval information from a third modality. We demonstrated that both moving and asynchronous static sounds can capture intermodal (visual-tactile and tactile-visual) apparent motion; moreover, while the auditory direction cues have less impact upon the perception of intramodal visual apparent motion than upon the perception of intramodal tactile or intermodal visual/tactile apparent motion, the auditory temporal information has equivalent impacts upon both intramodal and intermodal apparent motion. These findings suggest intermodal apparent motion is susceptible to the influence of dynamic or static auditory information in similar ways as intramodal visual or tactile apparent motion.

“…Also, a combination of spatial and temporal factors has been shown to affect audiovisual judgments of phenomenal causality on the basis of the saliency of the constituent perceptual events (i.e., without strict audiovisual synchrony being required; Guski & Troje, 2003). Common motion and other Gestalt grouping principles have also been shown to facilitate crossmodal binding (Lyons et al, 2006;Sanabria et al, 2004;SotoFaraco, Kingstone, & Spence, 2003;Spence et al, 2007;Vroomen & de Gelder, 2000).…”
