"... Abstract -We present a technique for automatically assigning a neuroanatomical label to each location on a cortical surface model based on probabilistic information estimated from Introduction Techniques for labeling geometric features of the cerebral cortex are useful for analyzing a variety of fu ..."

many techniques exist for labeling parts of the cortex The inclusion of prior information is a critical feature of a cortical parcellation algorithm. The reason this is the case is that the divisions that are useful in a cortical parcellation scheme can be based on properties of the brain other than

Treatment-induced cortical reorganization after stroke in humans

by Joachim Liepert, Md Heike Bauder, Phd Wolfgang, H. R. Miltner, Edward Taub, Phd Cornelius Weiller - Stroke , 2000
"... Background and Purpose—Injury-induced cortical reorganization is a widely recognized phenomenon. In contrast, there is almost no information on treatment-induced plastic changes in the human brain. The aim of the present study was to evaluate reorganization in the motor cortex of stroke patients tha ..."

of the paretic limb. Shifts of the center of the output map in the affected hemisphere suggested the recruitment of adjacent brain areas. In follow-up examinations up to 6 months after treatment, motor performance remained at a high level, whereas the cortical area sizes in the 2 hemispheres became almost

"... White matter is one of the two components of central nervous system and consists mostly of glialcells and myelinated axons that transmits signal from one region of the cerebrum to another and between cerebrum and lower brain centers. Multiple sclerosis (MS) is one of the most common diseases which a ..."

Brain-Computer Interface Research at the Wadsworth Center

by J. R. Wolpaw, D. J. McFarland, T. M. Vaughan - IEEE TRANS. REHAB. ENG , 2000
"... Studies at the Wadsworth Center over the past 14 years have shown that people with or without motor disabilities can learn to control the amplitude of or rhythms in electroencephalographic (EEG) activity recorded from the scalp over sensorimotor cortex and can use that control to move a cursor on a ..."

Action for perception: A motor-visual attentional effect

by Laila Craighero, Istituto Fisiologia, Umana Università Parma, Luciano Fadiga, Istituto Fisiologia, Umana Università Parma, Giacomo Rizzolatti, Istituto Fisiologia, Umana Università Parma, Carlo Umiltà - Journal of Experimental Psychology: Human Perception and Performance , 1999
"... Five experiments investigated whether preparation of a grasping movement affects detection and discrimination of visual stimuli. Normal human participants were required to prepare to grasp a bar and then to grasp it as fast as possible on presentation of a visual stimulus. On the basis of the degree ..."

Bottom-Up Modeling of Cerebro-Cerebellar Interaction

by Lily Kim, Sungho Jo, Kazutaka Takahashi, Steve G. Massaquoi
"... The Problem: To obtain systems engineering models of the interaction between the brain’s principal motor exec-utive center, the cerebrum, and its principal ’coordinating ’ center, the cerebellum. Motivation: Increasing scientific data about the primate cerebellum appears to show that the organ provi ..."

Motor and representational framing of space

by Jacques Paillard - In: J.Paillard (Ed). Brain and Space , 1991
"... The intention here is to focus on some motor-oriented approaches to the spatial functions of the brain and to see how far they contribute to our understanding of the way in which the internal metric of spatial information is neurally encoded. A motor-oriented approach assumes that the principal metr ..."

Artificial Fishes: Autonomous Locomotion, Perception, Behavior, and Learning in a Simulated Physical World

by Demetri Terzopoulos, Xiaoyuan Tu, Radek Grzeszczuk , 1994
"... This paper develops artificial life patterned after animals as evolved as those in the superclass Pisces. It demonstrates a virtual marine world inhabited by realistic artificial fishes. Our algorithms emulate not only the appearance, movement, and behavior of individual animals, but also the comp ..."
