DOI: 10.1007/s00221-021-06137-1
Abstract: Motion perception deficits in dyslexia show a large intersubjective variability, partly reflecting genetic factors influencing brain architecture development. In previous work, we have demonstrated that dyslexic carriers of a mutation of the DCDC2 gene have… read more here.

DOI: 10.1016/bs.pbr.2019.02.005
Abstract: To understand visual motion processing underlying the optokinetic response (OKR), we developed a biomimetic model that reproduces the findings from behavioral experiments. We recorded OKRs induced by drifting gratings with different spatiotemporal frequencies from humans… read more here.

DOI: 10.1016/j.heliyon.2021.e06457
Abstract: This paper presents an illusory visual motion stimulus-based brain-computer interface (BCI). We aim to use the proposed system to enhance the motor imagery (MI) modality. Since motor imagery requires a long time for training, a… read more here.

DOI: 10.1016/j.neuroimage.2017.01.010
Abstract: Abstract Sensory discriminations, such as judgements about visual motion, often benefit from multisensory evidence. Despite many reports of enhanced brain activity during multisensory conditions, it remains unclear which dynamic processes implement the multisensory benefit for… read more here.

DOI: 10.1016/j.neuroimage.2021.118299
Abstract: Visual motion discrimination involves reciprocal interactions in the alpha band between the primary visual cortex (V1) and mediotemporal areas (V5/MT). We investigated whether modulating alpha phase synchronization using individualized multisite transcranial alternating current stimulation (tACS)… read more here.
