Ra. Pigeau et al., ELECTROPHYSIOLOGICAL RECORDING AND ANALYSIS DURING PROTRACTED CONTINUOUS WORK EXPERIMENTS, Computer methods and programs in biomedicine, 39(3-4), 1993, pp. 323-332
A system is described that allows electrophysiological data to be coll
ected and analysed from sleep loss studies involving continuous cognit
ive work. This system needed to satisfy two major requirements. First,
the electrophysiological hardware had to be able to record extended p
eriods of physiology (often lasting 80 h) from multiple electrode site
s and yet be portable enough to allow subject mobility. Second, a comp
rehensive yet flexible procedure had to be developed to temporally map
the physiology to critical experimental events (e.g., all the behavio
ural tasks, sleeping and napping periods). The resulting system uses t
he Oxford Medilog 9000 for data acquisition and playback as well as a
custom software environment to digitize and analyse these data.
