Functional imaging methods monitor neural activity by measuring hemodynamic signals. These are more closely related to local field potentials (LFPs) than to action potentials. We simultaneously recorded electrical and hemodynamic responses in the cat visual cortex. Increasing stimulus strength enhanced spiking activity, high-frequency LFP oscillations, and hemodynamic responses. With constant s...

Introduction & Objective: Even a little bleeding can adversely affect the surgeon's ability to visualize the region to be operated in ENT operations. The aim of this study is to compare the effects of isoflurane and sevoflurane on hemodynamics and bleeding in controlled hypoten-sion. Materials & Methods: This study was a double-blind clinical trial. Ninety patients who were candidates for end...

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Background: Axillary block is used for inducing anesthesia in outpatient hand and forearm surgeries. Few researches have studied hemodynamic and blockade effects of low doses of Epinephrine. The aim of the present study was to compare the duration of analgesia and hemodynamic changes following the injection of high/low epinephrine doses in such surgeries. Methods: The present randomized clinic...

Introduction: In arthroplasty, spinal anesthesia was preferred to general anesthesia for a variety of reasons due to the use of cement. the side effects of cement on the cardiovascular system of patients, which can be catastrophic, it,s necessary to find appropriate treatment methods to reduce side effects of cement. method: In this clinical trial, 90 patients were arthroplasty candidates divid...
