Cerebral perfusion is maintained across a range of pressures via cerebral autoregulation. However, characterizing autoregulation requires prominent pressure fluctuations at regulated frequencies. The described protocol will show how oscillatory lower body negative pressure can generate pressure fluctuations to provide data for projection pursuit regression for quantification of the autoregulatory curve.

Task Interruption and Resumption Paradigm for Testing the Activation and Pursuit of an Abstract Thinking Goal
0 Views •
2017
This protocol was designed to test the activation and pursuit of cognitive goals (e.g., an abstract thinking goal) using the task interruption and resumption paradigm. The protocol is suitable for cognitive goals that are automatically pursued once activated, as the distraction procedure prevents goal pursuit during the interruption period.

A method is described to quantify the quality of visual information processing based on reflexive eye movements in response to specific visual modalities. Reaction times and fixation output parameters are used to characterize visual performance in children with and without visual impairments from 6 months of age.
FAQs
Smooth pursuit provides the continuous component of tracking by keeping the moving target aligned with the observer’s gaze. When the target changes speed or direction, tracking errors can appear. Brief saccades then act as corrective movements, helping restore alignment. Examining the balance between these movement types reveals how accurately visual information is converted into coordinated motor behavior.
Cortical and brainstem circuits connect visual signals with motor commands during tracking. This organization allows information about a moving object to influence eye movement continuously rather than producing isolated responses. Because pursuit depends on this distributed visuomotor pathway, changes in tracking can provide behavioral evidence about the coordination of visual processing and motor control.
Changes in speed or direction test whether tracking can adapt as visual demands shift. They may increase the difference between the target’s position and the current eye movement, requiring corrective saccades. Responses to these changes also provide information about prediction, attention, and the flexibility of visuomotor coordination rather than simply measuring whether an object can be seen.
An assessment presents a moving object and examines how the observer’s eyes respond while attention remains directed toward it. Researchers can consider the continuity of tracking and the occurrence of brief corrective saccades, especially when the object changes speed or direction. This approach produces a behavioral measure of visuomotor coordination, attention, and prediction.
Visual pursuit measures can characterize several linked functions, including sustained attention, prediction of motion, visuomotor coordination, and sensorimotor development. These functions are reflected in how effectively visual signals guide ongoing eye movements and corrections. The resulting behavioral pattern is therefore broader than a simple visual-performance score and can help describe coordinated behavior.
Researchers can use Visual Pursuit to compare normal behavioral performance with changes associated with neurological or visual-system dysfunction. It is also relevant when studying sensorimotor development, because tracking behavior reflects the coordination of visual perception and motor output. Its value comes from providing an observable behavioral indicator that links attention, prediction, and eye-movement control.
