Prefrontal cortex activation during incremental inspiratory loading in healthy participants

This study examined whether changes in prefrontal cortex oxyhemoglobin and deoxyhemoglobin were related to inspiratory muscle effort during inspiratory threshold loading in 14 healthy individuals. During the study, lung function testing (FEV1, FVC, FEV1/FVC ratio) was undertaken using the Vitalograph Asma-1 device.
