TI  - How Attention Changes in Response to Carbohydrate Mouth Rinsing.

AB  - Research investigating the effects of carbohydrate (CHO) mouth rinsing on 
      neurocognitive functions is currently limited and has yielded inconsistent 
      results. In this study, we employed the event-related potential (ERP) 
      electroencephalography technique to investigate the effect of CHO mouth rinsing 
      on electrophysiological correlates of visuospatial attention. Using a 
      double-blind, non-nutritive sweetener (NNS)-controlled, within-subjects design, 
      53 young adults performed a standard cognitive task (modified Simon task) on two 
      separate days in a fasted state (16 h). Intermittently, mouth rinsing was 
      performed either with a CHO (glucose, 18%, 30 mL) or an NNS solution (aspartame, 
      0.05%, 30 mL). Results revealed that relative to NNS, electrophysiological 
      correlates of both more bottom-up controlled visuospatial attention (N1(pc)-ERP 
      component) were decreased in response to CHO rinsing. In contrast, compared to 
      NNS, more top-down controlled visuospatial attention (N2(pc)-ERP component) was 
      increased after CHO rinsing. Behavioral performance, however, was not affected by 
      mouth rinsing. Our findings suggest that orosensory signals can impact 
      neurocognitive processes of visuospatial attention in a fasted state. This may 
      suggest a central mechanism underlying the ergogenic effects of carbohydrate 
      mouth rinsing on endurance performance could involve modulations of attentional 
      factors. Methodologically, our study underlines that understanding the effects of 
      carbohydrate mouth rinsing at the central level may require combining 
      neuroscientific methods and manipulations of nutritional states.
