[Laczko Jozsef <laczko.jozsef AT wigner.mta.hu>]

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.


Üdvözlettel,
