Does sustained inspiratory threshold loading elicit sustained preinspiratory cortical potentials (Bereitschaftspotentials) in healthy humans?
Sustained inspiratory loading is associated with enduring preinspiratory cortical potentials, suggesting continuous cerebral cortex involvement in compensating for mechanical inspiratory loads.
Tremoureux et al. (2010) conducted an observational in Healthy volunteers (n=9). Sustained inspiratory threshold loading vs. Unloaded quiet breathing was evaluated on Presence of a Bereitschaftspotential (BP) at the beginning and end of a session. Sustained inspiratory threshold loading elicited persistent preinspiratory cortical potentials in up to 8 of 9 healthy male volunteers over a 1-hour period.
