INTRODUCTION Simultaneously acquiring functional Near Infrared Spectroscopy (fNIRS) during Transcranial Magnetic Stimulation (rTMS) offers the possibility of directly investigating superficial cortical brain activation and connectivity. In addition, the effects of rTMS in distinct brain regions without quantifiable behavioral changes can be objectively(More)
The effects of using epinephrine in the irrigating fluid and intracameral acetylcholine were studied by measuring changes in pupil size in the 48 hours following extracapsular cataract extraction and intraocular lens implantation in 39 eyes. Epinephrine reduced peroperative pupil constriction, but its effect was insignificant thereafter. The pupil(More)
The purpose of the study was to determine whether chamber exposure to low levels of CO2 results in functional alterations in gas mixing and closing volume in humans. Four healthy volunteer subjects were exposed to 0.7% CO2 and to 1.2% CO2. Spirometry, lung volumes, single breath nitrogen washout, diffusing capacity for carbon monoxide (DLCO) by two methods,(More)
