Bio For over a decade my research career as a systems neuroscientist has been centered on measuring the brain in different states of consciousness using electrophysiology. Two ways to study conscious transitions empirically are by investigating the brain during sleep and while under anesthesia. I spent my doctoral and early postdoctoral work studying how sleep improves learning and memory at the neural network level. I am now studying the brain activity associated with anesthetic brain state transitions to broaden my understanding of the neural dynamics associated with altered conscious states. In fact, the brain shares similar electrophysiological activity patterns during sleep with some anesthetic transitions. With anesthetics, however, one is able to compare how different anesthetic agents interact with different neuromodulatory systems to cause similar behavior outcomes (i.e. sedation and unconsciousness).
My current projects explore and evaluate different computational approaches to quantify anesthetic depth using electrophysiology in various anesthetic protocols. A thorough characterization of the brain activity associated with brain state transitions during anesthesia administration is of critical importance to better monitor patients. This work is coupled with various initiatives to better predict patient outcomes. -
Koray Ertan
Postdoctoral Research Fellow, Radiological Sciences Laboratory
Bio Koray Ertan received his BSc degree in the Department of Electrical and Electronics Engineering at Bilkent University, Turkey. He completed his PhD in the same department under the supervision of Prof. Ergin Atalar. During his PhD, he worked as a researcher at National Magnetic Resonance Research Center (UMRAM) of Turkey. His thesis study is the development of novel magnetic resonance imaging (MRI) technologies such as gradient array systems for increasing diagnostic quality of the MR images, reducing the specific absorption rate and scan time.
He joined Prof. Brian Rutt's group as a postdoctoral researcher in April 2019. Later, he was also affilated as a MINDED postdoctoral fellow in June 2019. As part of the MINDED program, his current research focuses on a system for modulating the permeability of the blood brain barrier using focused radio frequency heating generated from ultra-high field MRI transmit coils for enhanced treatment of neurodevelopmental disorders with nanomedicines. Additionally, his research interest mostly includes MRI technolgies such as RF pulse design, gradient systems, field monitoring, multi-coil gradient and shim arrays.
