Optimizing Performance Through Sleep-Wake Homeostasis: Integrating Physiological and Neurobehavioral Data via Ambulatory Acquisition in Laboratory and Field Environments

摘要

The objective of our current AFOSR research (FA9550-05-1-0293) is to evaluate whether cognitive task difficulty from increased performance demands on attention will interact with acute total sleep loss and manifest in EEG slow wave energy and absolute cerebral blood flow(fMRI) measures of sleep-wake homeostasis. The instrumentation for which we received DURIP funding has three major components, each of which markedly enhances the quality of research and research-related education via our AFOSR project. The three components are: (1) Compumedics USA Siesta 802 Wireless & Ambulatory Recording System for ambulatory physiological acquisition and quantitative signal processing; (2) Brain Amp MR Plus 32 and BrainVision Recorder Professional Software Package for the simultaneous acquisition of EEG and fMRI data in the laboratory; and expansion of electronic data archive with simultaneous acceleration of data processing.
