Cycling reduces the entropy of neuronal activity in the human adult cortex

Iara Beatriz Silva Ferré, Gilberto Corso, Gustavo Zampier dos Santos Lima, S. R. Lopes, Mario André Leocádio-Miguel, Lucas G. S. França, Thiago de Lima Prado, John Fontenele Araújo

This study measures how cycling affects neuronal activity complexity in the human brain using EEG, finding reduced entropy during cycling compared to resting states.
