“…Corresponding to the presence of hemiparesis and abnormalities of the corticorespiratory projections in our patients, the lesions demonstrated by MRI have been located along the pyramidal tract [38,43] in the corona radiata, internal capsule, and the base of the pons. Our findings explain the observation of complete loss of voluntary respiration in patients with bilateral infarction in the base of the pons [41] and might contribute to the understanding why in a retrospective study including 71 patients with hemiparesis due to ischemia and unilateral pneumonia the incidence of pneumonia on the hemiparetic side was much higher than on the contralateral side (55 patients vs. 16 patients) [29].…”

“…Interestingly, loss of voluntary respiration with intact automatic breathing was previously reported in a patient with discrete infarction of the ventral basis pontis. 5 These support that there are at least 2 separate neural pathways controlling respiration.…”

“…The neural basis of the behavioural system of control therefore, includes corticospinal and/or corticobulbar pathways which permit voluntary modification of breathing, but also probably involve additional pathways from other suprapontine areas such as the limbic system. Recent clinical evidence indicates that emotions can affect breathing when volitional respiratory control is lost, following a lesion of the corticospinal tract (Munschauer, Mador, Ahuja & Jacob, 1991).…”

1. The cardiorespiratory response to imagination of previously performed treadmill exercise was measured in six competitive sportsmen and six non-athletic males. This was compared with the response to a control task (imagining letters) and a task not involving imagination ('treadmill sound only'). 2. In athletes, imagined exercise produced increases in ventilation which varied within and between subjects. The mean maximal increase (11 7 1 min-) was approximately 20 % of the ventilatory response to actual exercise. This was primarily due to treadmill speedrelated increases in respiratory frequency (mean maximal increase, 14-8 breaths min-') and resulted in significant reductions in end-tidal Pco, (mean maximal fall, 7 mmHg).These effects were greater (P < 0 01) than any observed during the control tasks.3. Changes in heart rate (mean increase, 12 beats min-1) were not significantly different from those observed during the control tasks (P > 0 2). 4. In non-athletes, imagination of exercise produced no changes in cardiorespiratory variables. No significant differences were detected in subjective assessments of movement imagery ability between athletes and non-athletes (P = 0-17). 5. This study demonstrates that ventilatory effects, when observed, are specific to imagination of exercise. The greater likelihood of generating ventilatory responses in highly trained athletes, experienced in 'rhythmic' sports, may be related to awareness of breathing and its role in exercise imagination strategy. A volitional component of the response cannot be discounted.
