Journal ArticleDOI
Decisional role of the dorsolateral prefrontal cortex in ocular motor behaviour.
Charles Pierrot-Deseilligny,René M. Müri,Christoph J. Ploner,Bertrand Gaymard,Sophie Demeret,Sophie Rivaud-Péchoux +5 more
TL;DR: The results suggest that the DLPFC plays a crucial role in the decisional processes, preparing saccade by inhibiting unwanted reflexive saccades (inhibition), maintaining memorized information for ongoing intentional sacces (short-term spatial memory) or facilitating anticipatory saccaders (prediction), depending upon current external environmental and internal circumstances.
Journal ArticleDOI
Cerebellar ataxia with oculomotor apraxia type 1: clinical and genetic studies
Isabelle Le Ber,Maria-Ceu Moreira,Sophie Rivaud-Péchoux,Céline Chamayou,François Ochsner,Thierry Kuntzer,Marc Tardieu,Gérard Said,Marie-Odile Habert,Geneviève Demarquay,Christian Tannier,Jean-Marie Beis,Alexis Brice,Michel Koenig,Alexandra Durr +14 more
TL;DR: The presence of chorea, sensorimotor neuropathy, oculomotor anomalies, biological abnormalities, cerebellar atrophy on MRI and absence of the Babinski sign can help to distinguish AOA1 from Friedreich's ataxia on a clinical basis.
Journal ArticleDOI
Frequency and phenotypic spectrum of ataxia with oculomotor apraxia 2: a clinical and genetic study in 18 patients.
Isabelle Le Ber,Naima Bouslam,Sophie Rivaud-Péchoux,João Guimarães,Ali Benomar,Céline Chamayou,Cyril Goizet,Maria-Ceu Moreira,Sandra Klur,Mohamed Yahyaoui,Yves Agid,Michel Koenig,Giovanni Stevanin,Alexis Brice,Alexandra Durr +14 more
TL;DR: It is shown for the first time that AOA2 can be found in Europe, North Africa and the West Indies, and its relative frequency represents approximately 8% of non-Friedreich ARCA, which is more frequent than ataxia telangiectasia and ataxIA with oculomotor apraxia type 1 (AOA1), in the authors' series of adult patients.
Journal ArticleDOI
Effects of Cortical Lesions on Saccadic
Ch. Pierrot-Deseilligny,Christoph J. Ploner,René M. Müri,Bertrand Gaymard,Sophie Rivaud-Péchoux +4 more
TL;DR: It has been shown that the posterior part of the anterior cingulate cortex, called the cingulates eye field, is involved in motivation and the preparation of all intentional saccades, but not in reflexive saccading.
Journal ArticleDOI
The frontal eye field is involved in spatial short-term memory but not in reflexive saccade inhibition.
TL;DR: Results show that the FEF is involved in short-term memorization of the parameters of the forthcoming memory-guided saccade encoded in oculocentric coordinates, and normal results in the antisaccade task suggest that theFEF is not involved in reflexive saccades inhibition.
