+Gz-induced loss of consciousness (G-LOC) results in incapacitation which can be characterized by the unconscious period (absolute incapacitation) and a subsequent period of confusion/disorientation (relative incapacitation). The sum of the absolute and relative incapacitation periods represents the total incapacitation period and may be equated to the(More)
Unconsciousness resulting from exposure to increased levels of head-to-foot (+Gz) acceleration stress (501 unconsciousness episodes) on a centrifuge in asymptomatic, healthy human subjects was investigated. A method for quantitatively measuring the kinetics of the unconsciousness and associated phenomenon was developed. In addition, a theoretical framework(More)
Eight healthy male volunteer members of the USAFSAM acceleration panel were exposed to two consecutive acceleration runs of +1 Gz to +7 Gz at 6 G.s-1 onset rates. The subjects were instructed to relax during the acceleration exposure in order to voluntarily induce loss of consciousness (LOC). The subjects were asked to relate dreams, thoughts, or other(More)
The anatomic relationships between arterial blood supply and key structures within the central nervous system (CNS) are important in comprehending the neurophysiological effects of acceleration (+Gz) stress, including +Gz-induced loss of consciousness (G-LOC). An accurate understanding of the location of the vascular and neurologic structures at eye-level(More)
Motivational analysis of a representative group of individuals who volunteer to participate in centrifuge acceleration research at the USAF School of Aerospace Medicine was performed. Monetary reward and curiosity were the main reasons for volunteering to participate in the research program. Fear and monetary reward not worth the risk were the main reasons(More)
