Etude anthropométrique de la main. Le volume et son utilisation pour l'aide à l'identification des personnes/Anthropometrical Study of the Hand. The Volume and its Utilization in Individuals Identification
Author(s) :
Lefèvre, Philippe
Description :
Dans nos sociétés culturelles, trois régions anatomiques sont habituellement apparentes et visibles donc identifiables :ce sont le visage et les mains. La main est donc un élément d’identification spécifique à chaque individu et reconnaissable. En mesurant le volume de la main démembrée d’une person...

Visuomotor Velocity Transformations for Smooth Pursuit Eye Movements
Description :
Blohm G, Lefevre P. Visuomotor velocity transformations for smooth pursuit eye movements. J Neurophysiol 104: 2103-2115, 2010. First published August 18, 2010; doi: 10.1152/jn.00728.2009. Smooth pursuit eye movements are driven by retinal motion signals. These retinal motion signals are converted in...

Dynamic Feedback To the Superior Colliculus in a Neural Network Model of the Gaze Control-system
Description :
The role of the superior colliculus (SC) has been explored in the context of the gaze control system, with the conclusion that recent data place it inside the control loop calculating gaze error A neural network proposed for the SC achieves both spatial and temporal integration of gaze signals. When...

Rhythmic feedback control of a blind planar juggler
Description :
The paper considers the feedback stabilization of periodic orbits in a planar juggler. The juggler is "blind," i.e, he has no other sensing capabilities than the detection of impact times. The robustness analysis of the proposed control suggests that the arms acceleration at impact is a crucial desi...

Sensorless stabilization of bounce juggling
Description :
The paper studies the properties of a sinusoidally vibrating wedge billiard as a model for 2-D bounce juggling. It is shown that some periodic orbits that are unstable in the elastic fixed wedge become exponentially stable in the nonelastic vibrating wedge. These orbits are linked with certain class...

Robotics and neuroscience: A rhythmic interaction
Description :
At the crossing between motor control neuroscience and robotics system theory, the paper presents
a rhythmic experiment that is amenable both to handy laboratory implementation and simple
mathematical modeling. The experiment is based on an impact juggling task, requiring the coordination
of two upp...

Timing Feedback Control of a Rhythmic System
Description :
This paper addresses the question relative to the
role of sensory feedback in rhythmic tasks. We study the
properties of a sinusoidally vibrating wedge-billiard as a model
for 2-D bounce juggling. If this wedge is actuated with an
harmonic sinusoidal input, it has been shown that some periodic
orbit...

OPEN-LOOP STABILIZATION OF 2D IMPACT JUGGLING
Description :
The paper studies the properties of a sinusoidally vibrating wedge
billiard as a model for 2D impact juggling. It is shown that some periodic orbits
that are unstable in the elastic xed wedge become exponentially stable in the
(non-)elastic vibrating wedge. These orbits are linked with some classic...

Direct evidence for a position input to the smooth pursuit system.
Description :
When objects move in our environment, the orientation of the visual axis in space requires the coordination of two types of eye movements: saccades and smooth pursuit. The principal input to the saccadic system is position error, whereas it is velocity error for the smooth pursuit system. Recently, ...

Properties of saccades in Duane retraction syndrome.
Description :
PURPOSE: To improve understanding of the binocular control of saccades by making high-resolution eye movement recordings in patients with unilateral Duane retraction syndrome (DRS) type I (marked by congenital absence of the sixth cranial nerve). METHODS: Binocular eye movements were recorded in fou...
