Key result
Expiratory loading significantly increased the presence of pre-expiratory potentials compared to unloaded breathing (93.75% vs 6.25% for high expiratory threshold load; P<0.001).
Why the study?
Does expiratory loading induce electroencephalographic premotor potentials in healthy humans?
Population

EEG signatures of cortical drive during expiratory loading can now be studied; leaves open any clinical translation to disease-related ventilatory control.

Expiratory loading induces cortical pre-expiratory potentials in healthy humans, providing a neurophysiological substrate for the cortical component of the response to expiratory loads.
Morawiec et al. (2015) studied Healthy volunteers (n=20). Expiratory loading vs. Unloaded breathing was evaluated on Presence of pre-expiratory potentials (p=<0.001). Expiratory loading significantly increased the presence of pre-expiratory potentials compared to unloaded breathing (93.75% vs 6.25% for high expiratory threshold load; P<0.001).
