Anatomical and Physiological Considerations in Vestibular Dysfunction and Compensation [PDF]
Seminars in Hearing, 2009 Sensory information from the vestibular, visual, and somatosensory/proprioceptive systems are integrated in the brain in complex ways to produce a final motor output to muscle groups for maintaining gaze, head and body posture, and controlling static and dynamic balance.

Physiology of Human Hemorrhage and Compensation
Comprehensive Physiology, 2021Abstract Hemorrhage is a leading cause of death following traumatic injuries in the United States. Much of the previous work in assessing the physiology and pathophysiology underlying blood loss has focused on descriptive measures of hemodynamic responses such as blood pressure, cardiac output, stroke volume ...

Physiological Noise Compensation in Gradient-Echo Myelin Water Imaging
NeuroImage, 2015 In MRI, physiological noise which originates from cardiac and respiratory functions can induce substantial errors in detecting small signals in the brain. In this work, we explored the effects of the physiological noise and their compensation methods in gradient-echo myelin water imaging (GRE-MWI).

Adaptive Filtering of Physiological Tremor for Real-Time Compensation
2008 IEEE International Conference on Robotics and Biomimetics, 2009Physiological tremor is one of the main cause for human imprecision during micro surgery. Accurate filtering of physiological tremor is extremely important for compensation in robotics assisted micro-surgical instruments/procedures. A study on surgeon's tremor is conducted and the characteristics of the tremor band and its nature are analyzed.

Force feedback teleoperation with physiological motion compensation
IFAC Proceedings Volumes, 2009Abstract In medical and surgical robotized applications one of the most recurrent problems is the physiological motion of the patient. Specifically, respiratory motion can have a large amplitude and thus prevent accurate gestures. So, for a robot which interacts with a patient, it is obvious that being able to compensate physiological motion would be ...

Distortion Compensating, Condenser-Earphone Driver for Physiological Studies
The Journal of the Acoustical Society of America, 1968A design for a condenser earphone driver is given. The driver predistorts electrical input signals to counteract the inherent square-law operation of the condenser earphone. Thus, smaller-diameter earphones, with their wider bandwidth characteristics, can be used at stimulus levels of interest without appreciable harmonic distortion.

Towards physiological motion compensation for flexible needle interventions
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015Flexible bevel-tipped needle steering has been an active research topic since the last decade. However, most of the work presented so far performs flexible needle steering in static phantoms or non-static virtual environments. The insertion of flexible bevel-tipped needles into soft-tissue subjected to motion disturbances is still an open research ...

Physiological compensation in unilateral eyestalk ablated crayfish, Cherax quadricarinatus
Journal of Experimental Zoology, 2001The eyestalks of crustaceans contain neurosecretory cells involved in the regulation of molting. In crayfish, bilateral ablation results in increased molting frequency and weight gain whereas unilateral ablation typically has no effect on molting frequency and weight gain.

Development of Portable Ultrasound Guided Physiological Motion Compensation Device
2017 IEEE International Conference on Cyborg and Bionic Systems (CBS), 2017Obtained image quality by ultrasound diagnostic device depends on skill of an operator. In addition, it is difficult to observe the image easily and precisely due to organ motions and deformations in accordance with breathing and pulsation. In this paper, we report a developed novel physiological motion compensation device to track and follow moving ...
