General Anesthesia and Human Brain Connectivity

Brain Stimulation and General Anesthesia

006 preliminary data points to a possible effect in acute pain [8]. Other types of stimulation, such as transcranial Pulsed Current Stimulation (tPCS), are also under experimental and clinical evaluation. None of the current techniques use the high energy previously related [1]. The correct parameters of stimulation to promote anesthesia, as well as the safety and efficacy of the association of...

Assessment of Anesthesia Depth Using Effective Brain Connectivity Based on Transfer Entropy on EEG Signal

Introduction: Ensuring an adequate Depth of Anesthesia (DOA) during surgery is essential for anesthesiologists. Since the effect of anesthetic drugs is on the central nervous system, brain signals such as Electroencephalogram (EEG) can be used for DOA estimation. Anesthesia can interfere among brain regions, so the relationship among different areas can be a key factor in the anesthetic process...

Depth of anesthesia estimation based on EEG signal using brain effective connectivity between frontal and temporal regions

Background: Ensuring adequate depth of anesthesia during surgery is essential for anesthesiologists to prevent the occurrence of unwanted alertness during surgery or failure to return to consciousness. Since the purpose of using anesthetics is to affect the central nervous system, brain signal processing such as electroencephalography (EEG) can be used to predict different levels of anesthesia....

Effects of Anesthesia on Effective Connectivity in the Brain

The brain constitutes a formidably complicated structural network. There are three main types of connectivity used to describe neuronal networks, which reflect three parallel levels of investigation: anatomical connectivity, functional connectivity and effective connectivity. Effective connectivity indicates the direct influence that a node exerts on another, and in the context of neuronal circ...
