Inspiratory muscle motoneurone pools are linked via many reflex connections. These reflexes are largely inhibitory and can operate over several segments. Much of our knowledge of these reflex connections comes from studies in animals (Marlot et al. 1988, Speck & Revelette. 1987). In humans, we know that stimulation of the phrenic nerve […]
Most of the time, our breathing is controlled involuntarily so that we don’t need to consciously think about breathing in and out all the time (for reviews, see Feldman & Del Negro, 2006; Richter & Smith, 2014). However, there are many instances where we need to voluntarily control how fast […]
Over 15 000 times every day we draw air into the lungs by expansion of the chest wall and abdomen; we breathe. This movement occurs by activation of inspiratory muscles from electrical signals from the brain to the respiratory motoneurones in the spinal cord. There are many inspiratory muscles that can […]
