“…Contrary to previous studies, we have not observed changes in the gamma frequency band for electrode C3. These modulations have been associated with tactile processing in other tactile discrimination tasks (Michail et al, 2016;Jiao et al, 2020;Ross et al, 2022), tactile spatial attention (Bauer et al, 2006), and multisensory communication (Misselhorn et al, 2019).…”

IntroductionTactile information processing requires the integration of sensory, motor, and cognitive information. Width discrimination has been extensively studied in rodents, but not in humans.MethodsHere, we describe Electroencephalography (EEG) signals in humans performing a tactile width discrimination task. The first goal of this study was to describe changes in neural activity occurring during the discrimination and the response periods. The second goal was to relate specific changes in neural activity to the performance in the task.ResultsComparison of changes in power between two different periods of the task, corresponding to the discrimination of the tactile stimulus and the motor response, revealed the engagement of an asymmetrical network associated with fronto-temporo-parieto-occipital electrodes and across multiple frequency bands. Analysis of ratios of higher [Ratio 1: (0.5–20 Hz)/(0.5–45 Hz)] or lower frequencies [Ratio 2: (0.5–4.5 Hz)/(0.5–9 Hz)], during the discrimination period revealed that activity recorded from frontal-parietal electrodes was correlated to tactile width discrimination performance between-subjects, independently of task difficulty. Meanwhile, the dynamics in parieto-occipital electrodes were correlated to the changes in performance within-subjects (i.e., between the first and the second blocks) independently of task difficulty. In addition, analysis of information transfer, using Granger causality, further demonstrated that improvements in performance between blocks were characterized by an overall reduction in information transfer to the ipsilateral parietal electrode (P4) and an increase in information transfer to the contralateral parietal electrode (P3).DiscussionThe main finding of this study is that fronto-parietal electrodes encoded between-subjects’ performances while parieto-occipital electrodes encoded within-subjects’ performances, supporting the notion that tactile width discrimination processing is associated with a complex asymmetrical network involving fronto-parieto-occipital electrodes.

“…However, the frequency-tagging approach is challenged by a contradictory view, i.e., neural entrainment, which argues SSVEP is at least partly generated by the endogenous entrainment of neural oscillations and thus can bring functional changes in cognitive processes (Keitel et al, 2019). It has been demonstrated that rhythmic sensory stimulation (RSS) can entrain endogenous neural oscillations and furtherly affect the subject's behaviors when they perform some mental tasks, such as attentional selection (Bauer et al, 2009;Gulbinaite et al, 2017), memory (Williams, 2001;Garcia-Argibay et al, 2019;Albouy et al, 2022) and spatial discrimination (Schlieper and Dinse, 2012;Ross et al, 2022). Such behavioral effects caused by RSS could be attributed to the rhythmic shifting of excitability in neuronal ensembles (Lakatos et al, 2008;Calderone et al, 2014) or the interaction between exogenous rhythmic input and endogenous neural rhythm (Spaak et al, 2014;Gulbinaite et al, 2017).…”

The rhythmic visual stimulation (RVS)-induced oscillatory brain responses, namely steady-state visual evoked potentials (SSVEPs), have been widely used as a biomarker in studies of neural processing based on the assumption that they would not affect cognition. However, recent studies have suggested that the generation of SSVEPs might be attributed to neural entrainment and thus could impact brain functions. But their neural and behavioral effects are yet to be explored. No study has reported the SSVEP influence on functional cerebral asymmetry (FCA). We propose a novel lateralized visual discrimination paradigm to test the SSVEP effects on visuospatial selective attention by FCA analyses. Thirty-eight participants covertly shifted their attention to a target triangle appearing in either the lower-left or -right visual field (LVF or RVF), and judged its orientation. Meanwhile, participants were exposed to a series of task-independent RVSs at different frequencies, including 0 (no RVS), 10, 15, and 40-Hz. As a result, it showed that target discrimination accuracy and reaction time (RT) varied significantly across RVS frequency. Furthermore, attentional asymmetries differed for the 40-Hz condition relative to the 10-Hz condition as indexed by enhanced RT bias to the right visual field, and larger Pd EEG component for attentional suppression. Our results demonstrated that RVSs had frequency-specific effects on left–right attentional asymmetries in both behavior and neural activities. These findings provided new insights into the functional role of SSVEP on FCAs.

“…Zimmer et al [ 22 ] found that emotional cues presented in multiple sensory modalities can improve visual attention. Ross et al [ 23 ] investigated the neural correlates of somatosensory processing using EEG and found that gamma oscillations in the somatosensory cortex are associated with the processing of vibrotactile stimulation. Brain functional area studies were utilized by Aricò et al [ 24 ], revealing that EEG alpha power is associated with attentional changes during cognitive tasks and virtual reality immersion sensory stimulations.…”

This study aimed to reveal the influence of emotional valence and sensory modality on neural activity in response to multimodal emotional stimuli using scalp EEG. In this study, 20 healthy participants completed the emotional multimodal stimulation experiment for three stimulus modalities (audio, visual, and audio-visual), all of which are from the same video source with two emotional components (pleasure or unpleasure), and EEG data were collected using six experimental conditions and one resting state. We analyzed power spectral density (PSD) and event-related potential (ERP) components in response to multimodal emotional stimuli, for spectral and temporal analysis. PSD results showed that the single modality (audio only/visual only) emotional stimulation PSD differed from multi-modality (audio-visual) in a wide brain and band range due to the changes in modality and not from the changes in emotional degree. The most pronounced N200-to-P300 potential shifts occurred in monomodal rather than multimodal emotional stimulations. This study suggests that emotional saliency and sensory processing efficiency perform a significant role in shaping neural activity during multimodal emotional stimulation, with the sensory modality being more influential in PSD. These findings contribute to our understanding of the neural mechanisms involved in multimodal emotional stimulation.
