Abstract

We investigated the impact of working memory (WM) load and sensory input reduction on prefrontal cortex (PFC) activity during standing in healthy younger individuals. We employed n-back tests to manipulate WM demand, while participants stood on foam or firm surfaces, to investigate sensory input reduction. Using an fNIRS device, we compared whole PFC activity, lateralisation index (LI), and activity per channel among different balance tests. While we found no significant differences in whole PFC activity and LI, the right DLPFC shows significant increased activation in response to WM load compared to sensory input reduction. Moreover, left DLPFC resources may not be heavily involved in WM during standing, and the left DLPFC's engagement remains unaffected by postural balance challenges in the presence of WM load. Our study contributes to understanding the PFCrole in postural balance and may have implications for rehabilitating and intervening in balance disorders.
