MENTALIST

Mental fatigue results from the prolonged engagement in demanding cognitive activities and is a significant public health problem in our modern society. Mental fatigue decreases cognitive and physical performances (e.g., alteration of speed and accuracy of movement, reduction in muscular endurance). It has been recently evidenced that the prolonged use of smartphone and social networks induces mental fatigue. This project aims to identify 1) the negative effects of mental fatigue induced by the prolonged use of smartphone and social networks on cognitive and motor performances in healthy young adults, and 2) the neurophysiological mechanisms underlying these alterations. This project, by using a multidisciplinary approach and combining electroencephalography and transcranial magnetic stimulation, will contribute to the identification of neurophysiological correlates of mental fatigue and improve its prevention and care.
