Chewing and Cognitive Improvement: The Side Matters.

Front Syst Neurosci 2021 23;15:749444. Epub 2021 Dec 23.

Department of Translational Research and of New Surgical and Medical Technologies, University of Pisa, Pisa, Italy.

Chewing improves cognitive performance, which is impaired in subjects showing an asymmetry in electromyographic (EMG) masseter activity during clenching. In these subjects, the simultaneous presence of an asymmetry in pupil size (anisocoria) at rest indicates an imbalance in Ascending Reticular Activating System (ARAS) influencing arousal and pupil size. The aim of the present study was to verify whether a trigeminal EMG asymmetry may bias the stimulating effect of chewing on cognition. Read More
