Control of the head involves somatosensory, vestibular, and visual feedback. The dynamics of these three feedback systems must be identified in order to gain a greater understanding of the head control system. We have completed one step in the development of a head control model by identifying the dynamics of the visual feedback system. A mathematical model of human head tracking of visual targets in the horizontal plane was fit to experimental data from seven subjects performing a visual head…

Behavioral and modeling studies of eye and head coordination
Moving eyes and head to orient the visual axis to a point of interest is a routine movement for foveate animals. From reading a book to driving a car or playing tennis, we constantly have to change…
Depth Judgment and Target Tracking from Eye Movements During Self-Motion
TLDR
The first study demonstrates that self-motion-derived parallax can elicit binocular eye movements in depth (vergence) and explores the dynamics of visual tracking behavior with the head free to move.

Human postural control during standing posture with a muscle-tendon actuator
TLDR
A new computational model dedicated to the study of human upright posture, with the presentation of a model of muscle-tendon actuator that reproduces the existing cross-correlation between experimentally observed and the neural signal and the centre of pressure.

TLDR
Horizontal head rotations were larger than horizontal eye rotations in both the "take" and "swing" conditions, and gaze was directed ahead of the ball late in the pitch trajectory in the " take" condition.
Robotic solutions to facilitate studying human motor control
TLDR
This work has devised an analysis method based on Fisher information to reduce the estimation error variance of SYSID outcomes, and presents some novel physical human-robot interaction (pHRI) tasks in the biomechanics field.
Feasibility of Incorporating Test-Retest Reliability and Model Diversity in Identification of Key Neuromuscular Pathways During Head Position Tracking
TLDR
This study investigates the feasibility of incorporating test-retest reliability in the previously published method of selecting sensitive parameters, and considers the selected parameters via this novel approach to be the key neuromuscular parameters.
Selecting Sensitive Parameter Subsets in Dynamical Models With Application to Biomechanical System Identification.
TLDR
A novel method to select sensitive biomechanical model parameters that should be estimated, while fixing the remaining parameters to values obtained from preliminary estimation, based on the Fisher information matrix.

Visual, vestibular and voluntary contributions to human head stabilization
TLDR
When subjects were distracted by mental arithmetic, the contribution to head stability of the short latency cervico-collic (CCR) and vestibulocollic (VCR) reflexes is negligible.
Mechanisms controlling human head stabilization. I. Head-neck dynamics during random rotations in the horizontal plane.
TLDR
The hypothesis that the relative importance of voluntary movements, vestibular and proprioceptive neck reflexes, and system mechanics depends on the frequency of an externally applied perturbation in producing compensatory actions of the head-neck motor system is tested.
Simulation of head movement trajectories: model and fit to main sequence
A sixth order nonlinear model for horizontal head rotations in humans is presented and investigated using experimental results on head movement trajectories and neck muscle EMG. The controller…
An investigation of horizontal combined eye-head tracking in patients with abnormal vestibular and smooth pursuit eye movements
Experimental tests of a superposition hypothesis to explain the relationship between the vestibuloocular reflex and smooth pursuit during horizontal combined eye-head tracking in humans.
TLDR
Evidence for the dynamic modulation of VOR gain is found by noting differences in responses to the onset and offset of head rotation in trials of the visually enhanced VOR.

Human eye-head coordination in two dimensions under different sensorimotor conditions
TLDR
This paper investigates head-free gaze saccades of human subjects towards visual as well as auditory stimuli presented in the two-dimensional frontal plane, under both aligned and unaligned initial fixation conditions and observes a systematic influence of the oculomotor response on the properties of the evoked head movements, indicating a subtle coupling between the two systems.
Visual motion processing and sensory-motor integration for smooth pursuit eye movements.
TLDR
It is argued that the visual inputs are transmitted through a simple sensory motor interface in the pons, to the efferent limb in the brain stem and cerebellum, and evidence is presented that the velocity memory is provided, at least in part, by eye velocity positive feedback between the flocculus of the Cerebellum and thebrain stem.
Human smooth pursuit: stimulus-dependent responses.
TLDR
The initial eye movements in response to unpredictable changes in target motion were analyzed to determine the effect of target velocity and position on the latency and acceleration of the response, and there was a large asymmetry in the responses to position steps.
