OBJECTIVES The study aims to characterize the electrical response of dorsal column axons to depolarizing stimuli to help understand the mechanisms of spinal cord stimulation (SCS) for the relief of chronic pain. MATERIALS AND METHODS We recorded electrically evoked compound action potentials (ECAPs) during SCS in 10 anesthetized sheep using stimulating(More)
Local anaesthetic agents can cause central nervous system (CNS) and cardiovascular system toxicity. Whereas most previous work has described their behavioural CNS effects qualitatively (i.e., absence or presence of convulsions), we wished to describe their CNS effects more quantitatively. We hypothesised that early CNS excitatory or disinhibitory effects(More)
INTRODUCTION Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly uses rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI) could be used for assessing sheep myocardium following an acute(More)
