A Neural Circuit for Angular Velocity Computation
In one of the most remarkable feats of motor control in the animal world, some Diptera, such as the housefly, can accurately execute corrective flight maneuvers in tens of milliseconds. These reflexive movements are achieved by the halteres, gyroscopic force sensors, in conjunction with rapidly tunable wing steering muscles. Specifically, the mechanosensory campaniform sensilla located at the b...
متن کاملEye movement studies with a vestibular prosthesis
Vestibular loss, which can manifest as dizziness, imbalance, or spatial disorientation, is widespread and often caused by inner ear hair cell malfunction. To address these problems, we are developing a vestibular implant analogous to cochlear implants for the deaf. This vestibular prosthesis provides pulsatile electrical stimulation to the vestibular nerve. Prosthesis effectiveness is assessed ...
متن کاملTowards a Wireless Implantable Vestibular Prosthesis
This paper presents the preliminary design of the integrated stimulator and telemetry subsystems for a vestibular prosthesis to restore balance function. The work is part of the European project CLONS. The stimulator is designed to provide biphasic current pulses at specified amplitude, duration and rate to stimulate the semicircular canals in the vestibular system. Power and data transfer is p...
متن کاملDecentralized attitude alignment control of spacecraft within a formation without angular velocity measurements ⋆
Abstract: In this paper, we consider the coordinated attitude control problem without velocity measurements. Based on the recently introduced unit quaternion output feedback for the attitude tracking of a rigid body, we present a class of decentralized coordinated control laws to solve the alignment problem for a group of spacecraft within a formation without velocity measurements. The approach...
متن کاملVestibular perception of angular velocity in normal subjects and in patients with congenital nystagmus.
A technique is described for the assessment of vestibular sensation. The two main goals of the study were (i) to compare the perception of angular velocity with the eye velocity output of the vestibulo-ocular reflex and (ii) to study vestibular function in patients with congenital nystagmus; this was needed since most previous studies, based on eye movement recordings, have been inconclusive. S...
