Changes in corticospinal drive to spinal motoneurones following tablet‐based practice of manual dexterity
The use of touch screens, which require a high level of manual dexterity, has exploded since the development of smartphone and tablet technology. Manual dexterity relies on effective corticospinal control of finger muscles, and we therefore hypothesized that corticospinal drive to finger muscles can be optimized by tablet-based motor practice. To investigate this, sixteen able-bodied females pr...
متن کاملPhysiological mechanisms of dyspnea during exercise with external thoracic restriction: role of increased neural respiratory drive.
We tested the hypothesis that neuromechanical uncoupling of the respiratory system forms the mechanistic basis of dyspnea during exercise in the setting of "abnormal" restrictive constraints on ventilation (VE). To this end, we examined the effect of chest wall strapping (CWS) sufficient to mimic a "mild" restrictive lung deficit on the interrelationships between VE, breathing pattern, dynamic ...
متن کاملFunctional Plasticity in the Respiratory Drive to Thoracic Motoneurons in the 1 Segment above a Chronic Lateral Spinal Cord Lesion
31 32 A previous neurophysiological investigation demonstrated an increase in functional projections of expiratory 33 bulbospinal neurons (EBSNs) in the segment above a chronic lateral thoracic spinal cord lesion which 34 severed their axons. We have now investigated how this plasticity might be manifested in thoracic 35 motoneurons, by measuring their respiratory drive and the connections to t...

متن کاملNeural respiratory drive in obesity.
BACKGROUND The load imposed on ventilation by increased body mass contributes to the respiratory symptoms caused by obesity. A study was conducted to quantify ventilatory load and respiratory drive in obesity in both the upright and supine postures. METHODS Resting breathing when seated and supine was studied in 30 obese subjects (mean (SD) body mass index (BMI) 42.8 (8.6) kg/m(2)) and 30 nor...
