We recently reported that visuospatial working memory capacity predicts the rate of explicit motor sequence learning (Bo and Seidler in J Neurophysiol 101:3116–3125, 2009). In the current study, we evaluated relationships between visuospatial and verbal working memory and implicit performance change in the serial reaction time (SRT) task. Participants(More)
We have recently demonstrated that visuospatial working memory performance predicts the rate of motor skill learning, particularly during the early phase of visuomotor adaptation. Here, we follow up these correlational findings with direct manipulations of working memory resources to determine the impact on visuomotor adaptation, a form of motor learning.(More)
This study examined the control of ventilation during repetitive bouts of isometric exercise in simulated sailing. Eight male sailors completed four successive 3-min bouts of similar isometric effort on a dinghy simulator, bouts were separated by 15-s rest intervals. Quadriceps muscle integrated electromyograph activity (iEMG) was recorded during each bout(More)
In anesthetised cats, breathing pattern, blood gases, and ventilatory response to CO2 were recorded before and during intermittent 10-minute episodes of hydrostatically raised intracranial pressure. The first effect on breathing was a stimulation which was followed at higher pressures by irregularity, depression, and periods of apnea; hyperventilation at(More)
Our recent work has revealed that visuospatial working memory (VSWM) relates to the rate of explicit motor sequence learning (Bo and Seidler in J Neurophysiol 101:3116–3125, 2009) and implicit sequence performance (Bo et al. in Exp Brain Res 214:73–81, 2011a) in young adults (YA). Although aging has a detrimental impact on many cognitive functions,(More)
Pentazocine and pethidine have been compared in the dose ratio 45:75 for their depression of respiration in normal subjects. The respective additive actions of the two drugs were investigated by comparing the effects of a single dose with those of two repeated half-doses. Some degree of ventilatory depression was found consistently. A first half-dose of(More)
Apparently new information about a metabolic abnormality has been obtained by measuring biochemical and respiratory responses to controlled exercise in a patient with abnormal mitochondria in muscle fibres. A male patient (49 years old) presented with bilateral ptosis of 15 to 20 years' duration and weakness for one to two years. Biopsies from the deltoid(More)
