Semidiscretization for time-delayed neural balance control

摘要: The observation that time-delayed feedback can stabilize an inverted pendulum motivates the formu- lation of models human balance control in terms delay differential equations (DDEs). Recently intermittent, digital-like nature neural has become evident. Here, semidiscretization methods for DDEs are used to investigate unstable dynamic system sub- jected a digital controller context switching model postural control. In addition limit cycle and chaotic ("microchaos") oscillations, transiently stabilized states possible even though both open-loop closed-loop systems globally unstable. possibility falls be intrinsic component may provide new insights into how risk falling elderly minimized.
