Intermanual coordination in relation to different clinical subgroups in right-handed patients with schizophrenic and other psychotic disorders.

BACKGROUND: Interhemispheric transfer in psychotic patients is still a controversial issue. Based on the fact that intermanual coordination is associated with interhemispheric transfer, scores in intermanual coordination were investigated in patients ...

Left prefrontal transcranial magnetic stimulation (TMS) treatment of depression in bipolar affective disorder: a pilot study of acute safety and efficacy.

OBJECTIVES: Repetitive transcranial magnetic stimulation (rTMS) has been shown to improve depressive symptoms. We designed and carried out the following left prefrontal rTMS study to determine the safety, feasibility, and potential efficacy of using TMS ...

Differential effects of developmental cerebellar abnormality on cognitive and motor functions in the cerebellum: an fMRI study of autism.

OBJECTIVE: Recent years have seen a revolution in views regarding cerebellar function. New findings suggest that the cerebellum plays a role in multiple functional domains: cognitive, affective, and sensory as well as motor. These findings imply that ...

Directional interference during bimanual coordination: is interlimb coupling mediated by afferent or efferent processes.

The role of afferent information in bimanual directional interference was studied by means of a modulation of the response-produced information in one of both limbs. In Experiment 1, visual information was either present, withdrawn, or shown with a ...

Influence of training on maintenance of equilibrium on a tilting platform.

To assess the influence of training on the maintenance of equilibrium on a tilting platform, 13 young healthy male athletes aged 19 to 33 years were randomly divided into experimental (n=7) and control (n=6) groups. Two experimental sessions were ...

Prediction precedes control in motor learning.

Skilled motor behavior relies on the brain learning both to control the body and predict the consequences of this control. Prediction turns motor commands into expected sensory consequences, whereas control turns desired consequences into motor commands. ...

3D analysis of posturo-kinetic coordination associated with a climbing task in children and teenagers.

The aim of this study was to characterize the modifications of the posturo-kinetic coordination during a climbing task as a function of postural and/or movement constraints in children (8-10 years) and adolescents (10-15 years). A 3D-analysis of forces ...

Learned dynamics of reaching movements generalize from dominant to nondominant arm.

Accurate performance of reaching movements depends on adaptable neural circuitry that learns to predict forces and compensate for limb dynamics. In earlier experiments, we quantified generalization from training at one arm position to another position. ...

Detection of intentional sub-optimal performance on a computerized finger-tapping task.

Twenty-four undergraduates were assigned to two groups to determine if the T3 computerized finger-tapping task could discriminate between persons motivated to perform optimally and those motivated to perform sub-optimally. Group HI was instructed to ...

Biomarkers for the effects of benzodiazepines in healthy volunteers.

Studies of novel centrally acting drugs in healthy volunteers are traditionally concerned with kinetics and tolerability, but useful information may also be obtained from biomarkers of clinical endpoints. A useful biomarker should meet the following ...
