Using Neuro-physiological Data to Improve Feedback Timing

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2013
The learning efficiency of complex tasks is an area being widely investigated in the literature. Specifically, many different instructional strategies have been developed in an effort to improve efficiency, especially within automated systems. Of particular interest are application methodologies which provide individual-ized recommendations.

Physiological Feedback Control 2011-2012 Annual Report

2013
Abstract : The research completed within this contract focused on the development of a platform that reverses the effects of an analgesic overdose (Tasks 1-3), and the development a platform that reverses the effects associated with organophosphate poisoning (Task 4). We successfully scaled up the synthesis of the naloxone prodrug that was designed and

Physiological Significance of the Negative Short-Loop Feedback of Prolactin

Neuroendocrinology, 1990
The aim of the present study was to evaluate the physiological significance of the rapid, short-loop, negative feedback of prolactin by passive immunization with antiserum to rat prolactin injected into the third cerebral ventricle (3V) of conscious, freely moving intact or castrated male rats.

Mechanoelectric Transduction/Feedback: Physiology and Pathophysiology

2007
Cardiac “mechanotransduction” involves various physiological and biophysical phenomena in which mechanical energy is transduced to changes in function of cardiac myocytes and of the whole heart. In this chapter different manifestations of mechanotransduction are reviewed, with special emphasis on the “mechano-electric” feedback aspect.

Periodic Diseases, Physiological Rhythms and Feedback Control—A Hypothesis

Australasian Annals of Medicine, 1970
SummaryConsideration of some general features of controlled biological systems and examination of a particular system, granulo‐poiesis, suggest that feedback control may be responsible for many physiological rhythms and for the periodic features observed in a number of diseases.

Dynamic feedback between phenotype and physiology in sexually selected traits

Trends in Ecology & Evolution, 2008
Theory predicts that physiological costs of producing elaborate phenotypes assure the honesty of sexually selected traits. It is generally assumed that these physiological processes drive sexually selected displays. However, a recent study by Safran and colleagues demonstrates that the manipulation of plumage ornaments in barn swallows alters the ...

Intelligent Physiological Monitoring and Feedback System for Driver Safety

2011 Fifth International Conference on Genetic and Evolutionary Computing, 2011
In the course of driving, sudden disease outbreak often cause serious traffic accidents. If drivers can real-time understand their physiological state, and then they could have a chance to get the best solution at the first time. Maybe accidents will be largely reduced.

Physiological signal feedback control tilting table for rehabilitation training

Proceedings of the 19th Annual International Conference of the IEEE Engineering in Medicine and Biology Society. 'Magnificent Milestones and Emerging Opportunities in Medical Engineering' (Cat. No.97CH36136), 2002
In this research, we design a physiological signal feedback closed-loop control tilting table for rehabilitation training. There have three close-loop control structures which monitor the tilting table. One is the blood pressure monitor. The others are the control loop of the degree of tilting table and the feedback control loop of the physiological ...

Cognitive and physiological feedback on cold pain tolerance.

Arctic medical research, 1995
Results supported the relevancy of cognitive information effects on pain tolerance, in that subjects who were given a rational and accurate explanation of what to expect showed greater tolerance than those who received irrelevant information. Accurate monitoring of hand temperature did not seem necessarily advantagous as an influence on pain tolerance.

Renal and Electrolyte Physiology The Juxtaglomerular Apparatus and Tubuloglomerular Feedback

Annual Review of Physiology, 1987
This series of papers discusses the juxtaglomerular apparatus (JGA) and its role in the control of renal hemodynamics and tubular function. As is often the case, these functional studies evolved from earlier morphological studies. In his monumental microdissection study of the nephronic structure of the mammalian kidney, published in 1909, the ...
