Les troubles de la marche et de l’équilibre dans les syndromes parkinsoniens « plus »
Autor: Marie-Laure Welter, N. Chastan, G.W.M. Westby
Publikováno v: Revue Neurologique. 166:188-195
Resume Les syndromes parkinsoniens « plus » d’origine degenerative constituent un ensemble heterogene de pathologies avec l’atrophie multisystematisee, la paralysie supranucleaire progressive, la demence a corps de Lewy et la degenerescence cor

Cerebral Vasomotion: A 0.1-Hz Oscillation in Reflected Light Imaging of Neural Activity
Autor: D. M. Rector, G.W.M. Westby, S Askew, John E. W. Mayhew, J Porrill, Ronald M. Harper, Ying Zheng, Peter Redgrave
Publikováno v: NeuroImage. 4:183-193
Imaging of scattered and reflected light from the surface of neural structures can reveal the functional architecture within large populations of neurons. These techniques exploit, as one of the principal signal sources, reflectance changes produced

Influence of sensory inputs and motor demands on the control of the centre of mass velocity during gait initiation in humans
Autor: Manh-Cuong Do, Marie-Laure Welter, S. Tezenas du Montcel, N. Chastan, Yves Agid, Raymond K.Y. Chong, G.W.M. Westby
Publikováno v: Neuroscience letters. 469(3)
Human gait requires the simultaneous generation of goal-directed continuous movement (locomotion) and the maintenance of balance (postural control). In adults, the centre of mass (CoM) oscillates in the vertical plane while walking. During the single

International audience; The physiopathology of gait and balance disorders in Parkinson's disease patients is still poorly understood. Levodopa treatment and subthalamic nucleus (STN) stimulation improve step length and walking speed, with less effect

Organization of the crossed tecto-reticulo-spinal projection in rat—I. Anatomical evidence for separate output channels to the periabducens area and caudal medulla
Autor: G.W.M. Westby, Paul Dean, Peter Redgrave
Publikováno v: Neuroscience. 37:571-584
The superior colliculus has been used to study principles of sensorimotor transformation underlying the guidance of orienting movements by multimodal sensory stimuli. We have previously suggested that there may be two different classes of mechanism w

Cerebellar output exerts spatially organized influence on neural responses in the rat superior colliculus
Autor: G.W.M. Westby, U.J Niemi-Junkola
Publikováno v: Neuroscience. 97(3)
The deep cerebellar nuclei project to largely segregated target regions in the contralateral superior colliculus. Single-unit recordings have previously shown that nuclear inactivation normally suppresses spontaneously active collicular target neuron

Bicuculline-induced circling from the rat superior colliculus is blocked by GABA microinjection into the deep cerebellar nuclei
Autor: G.W.M. Westby, J. M. Speller
Publikováno v: Experimental brain research. 110(3)
In a recent electrophysiological experiment, we showed the deep cerebellar nuclei to be a major source of excitatory input to the superior colliculus. Furthermore, target neurons in the colliculus were found, in every case, to receive convergent toni

Chapter 7 Functional architecture of rodent superior colliculus: relevance of multiple output channels
Autor: Peter Redgrave, G.W.M. Westby, Paul Dean
Publisher Summary The main function assigned to the superior colliculus is saccadic redirection of the eyes and/or head toward a suddenly appearing visual or other stimulus. The effects of damaging or stimulating the superior colliculus in rodents ha

Output pathways from the rat superior colliculus mediating approach and avoidance have different sensory properties
Autor: G.W.M. Westby, Peter Redgrave, K. A. Keay, M. Bannister, Paul Dean
Publikováno v: Experimental brain research. 81(3)
Neuroanatomical studies have demonstrated that the two major descending pathways from the superior colliculus arise from regionally segregated, distinct, cells of origin. Stimulation and lesion studies have implicated the crossed descending tecto-ret
