Skull vibration induced nystagmus, velocity storage and self-stability. [PDF]
Front NeurolIn this paper we give an introduction to the area, followed by brief reviews of the neural response to sound and vibration, and then the velocity storage integrator, before putting forward our hypothesis about the neural input to the velocity storage ...

Coding of Velocity Storage in the Vestibular Nuclei. [PDF]
Front Neurol, 2017 Semicircular canal afferents sense angular acceleration and output angular velocity with a short time constant of ≈4.5 s. This output is prolonged by a central integrative network, velocity storage that lengthens the time constants of eye velocity.

The velocity storage time constant: Balancing between accuracy and precision. [PDF]
Prog Brain Res, 2019 The velocity storage mechanism is often described in terms of the exponential decay in eye velocity in an upright subject who experiences a constant velocity yaw rotation after a rapid acceleration. The velocity storage time constant for this decay is roughly 6-30s, which means that for low-frequency head rotations, eye velocity and perceptions have ...

Velocity storage mechanism drives a cerebellar clock for predictive eye velocity control. [PDF]
Sci Rep, 2020 AbstractPredictive motor control is ubiquitously employed in animal kingdom to achieve rapid and precise motor action. In most vertebrates large, moving visual scenes induce an optokinetic response (OKR) control of eye movements to stabilize vision. In goldfish, the OKR was found to be predictive after a prolonged exposure to temporally periodic visual

How Peripheral Vestibular Damage Affects Velocity Storage: a Causative Explanation. [PDF]
J Assoc Res Otolaryngol, 2022 Velocity storage is a centrally-mediated mechanism that processes peripheral vestibular inputs. One prominent aspect of velocity storage is its effect on dynamic responses to yaw rotation. Specifically, when normal human subjects are accelerated to constant angular yaw velocity, horizontal eye movements and perceived angular velocity decay ...

Gravity-Dependent Modulation of Downbeat Nystagmus: Insights From Velocity-Storage Dysfunction. [PDF]
Ann Clin Transl NeurolABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

The functional significance of velocity storage and its dependence on gravity [PDF]
Experimental Brain Research, 2011 Research in the vestibular field has revealed the existence of a central process, called 'velocity storage', that is activated by both visual and vestibular rotation cues and is modified by gravity, but whose functional relevance during natural motion has often been questioned. In this review, we explore spatial orientation in the context of a Bayesian
