Assessing rheoencephalography dynamics through analysis of the interactions among brain and cardiac networks during general anesthesia
(Frontiers Media SA, 2022-08-29)
Article
Open AccessCerebral blood flow (CBF) reflects the rate of delivery of arterial blood to the brain. Since no nutrients, oxygen or water can be stored in the cranial cavity due to space and pressure restrictions, a continuous perfusion ... -
Assessing the coupling between local neural activity and global connectivity fluctuations: Application to human intracranial electroencephalography during a cognitive task
(2022-01-01)
Article
Open AccessCognitive-relevant information is processed by different brain areas that cooperate to eventually produce a response. The relationship between local activity and global brain states during such processes, however, remains ... -
Assessment of sedation-analgesia by means of Poincaré analysis of the electroencephalogram
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference lecture
Open AccessMonitoring the levels of sedation-analgesia may be helpful for managing patient stress on minimally invasive medical procedures. Monitors based on EEG analysis and designed to assess general anesthesia cannot distinguish ... -
