Event-related desynchronization (ERD) is the short-lasting attenuation or blocking of rhythms within the alpha (beta) band. ERD is found during but also before visual stimulation. Two different types of ERD can be differentiated: one short-lasting, localized to occipital areas and involving upper alpha components; the other longer lasting, more widespread,(More)
Event-related desynchronization (ERD) is the amount of event-related decrease in alpha band power. In applying ERD as an index of cortical activation, the way in which attention and expectancy affect hemispheric differences for words and numbers was investigated. Subjects, 12 right-handed males, had to perform a semantic and a numerical classification task(More)
Thirty channels of EEG data were recorded prior to voluntary right or left hand movements. Event-related desynchronization (ERD) was quantified in the 8-10 Hz and 10-12 Hz bands in single-trial data and used as training input for a neural network comprised of a learning vector quantizer (LVQ). After a training period, the network was able to predict the(More)

Considering the complex nature of the adult heart, it is no wonder that innate regenerative processes, while maintaining adequate cardiac function, fall short in myocardial jeopardy. In spite of these enchaining limitations, cardiac rejuvenation occurs as well as restricted regeneration. In this review, the background as well as potential mechanisms of(More)
The effect of pressure-controlled intermittent coronary sinus (CS) occlusion on myocardial infarction (MI) size was evaluated. A device for this purpose was developed that consisted of a balloon catheter and pump system that produced controlled, intermittent occlusion of the CS and used CS pressure as a feedback to determine the duration of occlusion. It(More)
OBJECTIVES This study investigated the feasibility, accuracy and clinical potential of creating polymer hard copies of echocardiographic data using stereolithography. BACKGROUND Three-dimensional (3D) echocardiography has so far been limited by the need to display reconstructed 3D objects on a two-dimensional screen. Thus, tangible stereolithographic(More)
OBJECTIVES Intermittent coronary sinus occlusion has been described to be effective in salvaging ischemic myocardium. This meta-analysis aims to review the efficacy of intermittent coronary sinus occlusion and intermittent coronary sinus occlusion in combination with retroperfusion of arterial blood as methods of myocardial salvage.
