The effect of the volatile anesthetic desflurane on motor evoked potentials was examined in male rats. Animals underwent cortical stimulation using small platinum ball stimulating electrodes secured on the motor cortex. To record evoked compound muscle action potentials (CMAPs), single-shock electrical stimulation was delivered to the forelimb(More)
The effect of the volatile anesthetic desflurane on spinal and cortical somatosensory evoked potentials (SEPs) was examined in 11 Sprague-Dawley male rats. Platinum recording electrodes were placed stereotactically over the left somatosensory cortex and dorsal midline of the T11-12 spinal cord while the right posterior tibial nerve was stimulated at twice(More)
Motor-evoked potentials (MEPs) from forearm muscles were recorded in response to single-shock electrical stimulation of motor cortex of rats (n = 15) under pentobarbital anesthesia and controlled room air ventilation. In addition, electroencephalograms (EEGs) were recorded for all animals. Following baseline MEP recording in room air (21% O2), animals were(More)
SUMMARY We review advances in GaN-based microwave power field-effect-transistors (FETs). Evolution in device technology included metal-semiconductor-field-effect-transistors (MESFETs), heterostructure-field-effect-transistors (HFETs), modulation-doped-field-effect-transistors (MODFETs) or high-mobility-transistors (HEMT), HEMTs with high Al contents, HEMTs(More)
The effects of halogenated anesthetic agents on somatosensory and motor evoked potentials (MEP) have been documented previously. Intravenous anesthetic propofol has not yet been used during MEP monitoring. This study investigates the effects of propofol on transcortical MEP in rats during bolus, infusion, and recovery conditions. After baseline MEP(More)
