Tisztelt Kollégák!

Tisztelettel meghívjuk Önöket a Wigner FK szemináriumára,

Cím: “Motor Control of Object Manipulation. Normal Behavior and Consequences of Brain Damage”

Előadó: Prof. Joachim Hermsdörfer
(Chair of Human Movement Science, Technical University of Munich)

Az előadás 2017 július 11-én kedden 13:10-kor kezdődik
a KFKI campus 1. épület tanácstermében.

Kivonat: During object manipulation adequate grip forces must be generated that are high enough to prevent slippage of the grasped object but are low enough to avoid fatigue or object damage. During movements of grasped objects acceleration dependent inertial loads add to gravitational loads. It has been shown that grip force precisely anticipate the physical load. The first part of the presentation presents data on grip force control during dynamic loading in microgravity, in conditions of skin anesthesia and cortical or cerebellar lesions. Grip force also anticipate physical properties of the object such as size and weight. In another series of experiments we investigated how healthy subjects and stroke patients anticipate the size, the material, the center of gravity and finally the identity of grasped and lifted object. Interestingly only the later condition posed serious problem on force scaling with the left non-paretic hand in stroke patients with left brain damage.

A szemináriumon Prof. Jürgen Konczak (University of Minnesota, Schhol of Kinesiology) is bemutatja munkáját. Erről részleteket később írunk.
