“…For the AV discrimination task, the visual non-target stimulus was a black and white checkerboard image (B/W checkerboard, 52 × 52 mm, with a visual angle of 5 • ), and the visual target stimulus was a B/W checkerboard image with two black dots contained within each white checkerboard (He et al, 1996;Talsma and Woldorff, 2005;Ren et al, 2016). The auditory nontarget stimulus was a 1000 Hz sinusoidal tone, and the auditory target stimulus was white noise (Yang et al, 2015;Ren et al, 2016Ren et al, , 2018b. The AV target stimulus was the combination of visual target and auditory target stimuli, and the AV non-target stimulus was the combination of visual non-target and auditory non-target stimuli.…”

“…According to previous studies and topographic response patterns, five regions of interest (ROIs) (frontal: F7, F3, Fz, F4, F8; fronto-central: FC5, FC1, FC2, FC6; central: C3, Cz, C4; centroparietal: CP5, CP1, CP2, CP6; and occipital: O1, Oz, O2) in the 0-600 ms time interval were selected (Yang et al, 2015;Ren et al, 2018b). One-way ANOVA showed no significant lateralization effect for any of these ROIs; therefore, we chose one representative electrode with the highest activity in each ROI (Fz, FC1, Cz, CP1, and Oz) for further analysis.…”

Audiovisual integration (AVI) is higher in attended conditions than in unattended conditions. Here, we explore the AVI effect when the attentional recourse is competed by additional visual distractors, and its aging effect using single-and dual-tasks. The results showed the highest AVI effect under single-task-attentional-load condition than under no-and dual-task-attentional-load conditions (all P < 0.05) in both older and younger groups, but the AVI effect was weaker and delayed for older adults compared to younger adults for all attentional-load conditions (all P < 0.05). The non-phase-locked oscillation for AVI analysis illustrated the highest theta and alpha oscillatory activity for single-taskattentional-load condition than for no-and dual-task-attentional-load conditions, and the AVI oscillatory activity mainly occurred in the Cz, CP1 and Oz of older adults but in the Fz, FC1, and Cz of younger adults. The AVI effect was significantly negatively correlated with FC1 (r 2 = 0.1468, P = 0.05) and Cz (r 2 = 0.1447, P = 0.048) theta activity and with Fz (r 2 = 0.1557, P = 0.043), FC1 (r 2 = 0.1042, P = 0.008), and Cz (r 2 = 0.0897, P = 0.010) alpha activity for older adults but not for younger adults in dual task. These results suggested a reduction in AVI ability for peripheral stimuli and a shift in AVI oscillation from anterior to posterior regions in older adults as an adaptive mechanism.

“…One example from among life experiences is that we generally see lightning and then hear the thunderclap, although the lightning and thunderclap occur simultaneously. This phenomenon indicates that the integration of multiple forms of sensory information obeys the temporal principle ( Stein, 2012 ; Ren et al, 2017a ). When auditory and visual signals occur at the same time and location, they tend to be integrated, and temporal proximity is always a necessary factor for the occurrence of audiovisual integration ( Van der Burg et al, 2008 ; Ren et al, 2017b ).…”

“…Audiovisual integration is involved in multiple brain regions, including the occipital, parietal, temporal, and frontal regions ( Shams et al, 2005 ). Previous functional magnetic resonance imaging (fMRI) and EEG studies have yielded evidence of audiovisual integration effect occurrence in regions traditionally considered sensory specific (e.g., primary visual cortex) ( Calvert et al, 2000 ; Macaluso, 2006 ; Chan et al, 2017 ; Ren et al, 2017a ). Moreover, direct anatomical connections between the occipital regions (visual processing) and superior temporal regions (auditory processing) have confirmed that these regions may play key roles in audiovisual integration ( Falchier et al, 2002 ).…”

Audiovisual integration significantly changes over the lifespan, but age-related functional connectivity in audiovisual temporal asynchrony integration tasks remains underexplored. In the present study, electroencephalograms (EEGs) of 27 young adults (22–25 years) and 25 old adults (61–76 years) were recorded during an audiovisual temporal asynchrony integration task with seven conditions [auditory (A), visual (V), AV, A50V, A100V, V50A and V100A]. We calculated the phase lag index (PLI)-weighted connectivity networks modulated by the audiovisual tasks and found that the PLI connections showed obvious dynamic changes after stimulus onset. In the theta (4–7 Hz) and alpha (8–13 Hz) bands, the AV and V50A conditions induced stronger functional connections and higher global and local efficiencies, reflecting a stronger audiovisual integration effect, which was attributed to the auditory information arriving at the primary auditory cortex earlier than the visual information reaching the primary visual cortex. Importantly, the functional connectivity and network efficiencies of old adults revealed higher global and local efficiencies and higher degree in both the theta and alpha bands. These larger network efficiencies indicated that old adults might experience more difficulties in attention and cognitive control during the audiovisual integration task with temporal asynchrony than young adults. There were significant associations between network efficiencies and peak time of integration only in young adults. We propose that an audiovisual task with multiple conditions might arouse the appropriate attention in young adults but would lead to a ceiling effect in old adults. Our findings provide new insights into the network topography of old adults during audiovisual integration and highlight higher functional connectivity and network efficiencies due to greater cognitive demand.

“…To date, although there is no evidence of pathology in the visual cortex of PD patients, the present studies have implied the dysfunction of visual perception, and reduced activity in visual association cortices and primary visual cortex was found in PD [ 38 , 39 ]. The regions traditionally considered to be sensory-specific (e.g., the primary visual cortex) have been proven an audiovisual integration effect as compensatory phenomena [ 40 – 43 ]. Therefore, it is reasonable for the abnormal audiovisual integration in PD patients.…”

The basal ganglia, which have been shown to be a significant multisensory hub, are disordered in Parkinson's disease (PD). This study was to investigate the audiovisual integration of peripheral stimuli in PD patients with/without sleep disturbances. Thirty-six age-matched normal controls (NC) and 30 PD patients were recruited for an auditory/visual discrimination experiment. The mean response times for each participant were analyzed using repeated measures ANOVA and race model. The results showed that the response to all stimuli was significantly delayed for PD compared to NC (all p < 0.01). The response to audiovisual stimuli was significantly faster than that to unimodal stimuli in both NC and PD (p < 0.001). Additionally, audiovisual integration was absent in PD; however, it did occur in NC. Further analysis showed that there was no significant audiovisual integration in PD with/without cognitive impairment or in PD with/without sleep disturbances. Furthermore, audiovisual facilitation was not associated with Hoehn and Yahr stage, disease duration, or the presence of sleep disturbances (all p > 0.05). The current results showed that audiovisual multisensory integration for peripheral stimuli is absent in PD regardless of sleep disturbances and further suggested the abnormal audiovisual integration might be a potential early manifestation of PD.
