The basal ganglia control body movements, value processing and decision-making. Many studies have shown that the inputs and outputs of each basal ganglia structure are topographically organized, which suggests that the basal ganglia consist of separate circuits that serve distinct functions. A notable example is the circuits that originate from the rostral (head) and caudal (tail) regions of th...

Thrombingeneration vor und nach Multikomponentenspende

IThe development of apheresis technology has increased efficiency in donor blood use by collecting specific blood components in several combinations. The question of donor safety raised by the contact of donor blood with foreign, only in part biocompatible surfaces remains. The aim of this study was to estimate the effect of multicomponent blood collection on thrombin generation performing an o...

Learning VOR-like stabilization reflexes in robots

We present a binocular robot that learns compensatory camera movements for image stabilization purposes. Most essential in achieving satisfactory image stabilization performance is the exploitation/integration of different self-motion information. In our robot, self-motion is measured inertially through an artificial vestibular apparatus and visually using basic motion detection algorithms. The...

Semicircular canal occlusion causes permanent VOR changes.

We measured the guinea pig horizontal vestibulo-ocular reflex (hVOR) to high acceleration impulsive head rotations following a unilateral lateral semicircular canal (LSCC) occlusion. We found a significant hVOR deficit for rotations toward the side of the occluded LSCC and this deficit did not show systematic changes over 3 months. We considered the LSCC nerve was still functional as shown by t...
