T1 - Visual inputs decrease brain activity in frontal areas during silent lipreading LA - eng PY - 2019 T2 - PLoS ONE SN - 1932-6203 VL - 14 IS - 10 PB - Public Library of Science AB - Aim The aim of the present work is to analyze the modulation of the brain activity within the areas involved in lipreading when an additional visual stimulus is included. Methods The experiment consisted of two fMRI runs (lipreading_only and lipreading+picture) where two conditions were considered in each one (oral speech sentences condition [OSS] and oral speech syllables condition [OSSY]). Results During lipreading-only, higher activity in the left middle temporal gyrus (MTG) was identified for OSS than OSSY; during lipreading+picture, apart from the left MTG, higher activity was also present in the supplementary motor area (SMA), the left precentral gyrus (PreCG) and the left inferior frontal gyrus (IFG). The comparison between these two runs revealed higher activity for lipreading-only in the SMA and the left IFG. Conclusion The presence of a visual reference during a lipreading task leads to a decrease in activity in frontal areas.
