Inferring neural dynamics during burst suppression using a neurophysiology-inspired switching state-space model
Gabriel Schamberg, Sourish Chakravarty, Taylor E. Baum +1
Burst suppression is an electroencephalography (EEG) pattern associated with profoundly inactivated brain states characterized by cerebral metabolic depression. Its distinctive fea…
Constructing a control-ready model of EEG signal during general anesthesia in humans
John H. Abel, Marcus A. Badgeley, Taylor E. Baum +3
Significant effort toward the automation of general anesthesia has been made in the past decade. One open challenge is in the development of control-ready patient models for closed…
A state-space model for dynamic functional connectivity
Sourish Chakravarty, Zachary D. Threlkeld, Yelena G. Bodien +2
Dynamic functional connectivity (DFC) analysis involves measuring correlated neural activity over time across multiple brain regions. Significant regional correlations among neural…
A simulation-based comparative analysis of PID and LQG control for closed-loop anesthesia delivery
Sourish Chakravarty, Ayan S. Waite, John H. Abel +1
Closed loop anesthesia delivery (CLAD) systems can help anesthesiologists efficiently achieve and maintain desired anesthetic depth over an extended period of time. A typical CLAD…
