Based on the neurophysiology of dyspnoea and the distribution of cannabinoid receptors within the central nervous system, we hypothesize that the unpleasantness of breathlessness will be ameliorated in humans by cannabinoids, without respiratory depr

We employed an associative learning paradigm to test the hypothesis that exercise hyperpnea in humans arises from learned responses forged by prior experience. Twelve subjects undertook a “conditioning” and a “nonconditioning” session on sepa

Vagus nerve stimulation is used to reduce the frequency and intensity of seizures in patients with epilepsy. In the present study four such patients were studied while awake. We analyzed the physiological responses to vagus nerve stimulation over a b

We have determined whether changes in [Formula: see text]above and below eucapnia modulate the precision of the voluntary control of breathing. Twelve trained subjects performed a compensatory tracking task in which they had to maintain the position

Sheep cathepsin G (CG) and neutrophil elastase (NE) were isolated from a crude leukocyte membrane preparation by elastin-Sepharose 4B and CM-Sepharose 4B chromatography, followed by native preparative PAGE. The N-termini of CG and NE were sequenced t

We studied physiological and sensory effects of left cervical vagal stimulation in six adult patients receiving this stimulation as adjunctive therapy for intractable epilepsy. Stimulus strength varied among subjects from 0.1 to 2.1 microCoulomb (mic
Does the motor cortical control of the diaphragm ‘bypass’ the brain stem respiratory centres in man?

In humans, cortico-motor excitation of the diaphragm may act directly on the phrenic motor nucleus via the cortico-spinal tract 'bypassing' brain stem respiratory centres (RC); alternatively, or in addition, this control may be indirect via the RC an

We tested whether subjects could detect and localize inflation confined to a single lung lobe. A balloon-sealed catheter was placed into a lobar bronchus of unsedated subjects via fiberoptic bronchoscopy. Topical anesthesia (lidocaine) was used to su

Control of breathing was studied in a patient with a lesion in the ventral pons; no volitional behaviour, including voluntary breathing acts, was possible (locked-in syndrome, LIS). Spontaneous breathing via a tracheostomy maintained a normal PETCO2
