Vestibular Research Laboratory
The Vestibular Research Lab at the ENT Department of the Benjamin Franklin Medical Center, Free University of Berlin was founded in 1986. In 2003 the Center was fusioned into the newly formed Charité Universitämedizin Berlin.
Our research and clinical interests include:
Examination of the three-dimensional aspects of the vestibulo-oculomotor system.
Adaptation of the VOR during prolonged microgravity.
These topics are currently the subject of a series of experiments conducted onboard
the International Space Station, in cooperation with the German, European,
Russian and US space agencies (DLR, ESA, RSA, IMBP, NASA).
Morphological and physiological aspects of the semicircular canals and otolith organs.
Recent publications deal with the structure of the cupula, and the cell populations of the crista ampullaris.
Introduction of novel clinical test, particularly for unilateral otolith function.
The refinement of the unilateral centrifugation technique permits unilateral testing
of the utricle. Together with the use of vestibular evoked myogen potentials (VEMP),
which reflect the function of the saccule, comprehensive testing of the peripheral otolith function is possible.
-
Interaction of the vestibular and autonomic systems, with regard to kinetosis.
This work is performed in cooperation with the DLR, Hamburg.
Design of new measurement technologies (currently 1000 Hz eye tracker and improved universal vestibular goggles).
Over the last 15 years our laboratory has been instrumental in establishing the video-oculography
approach to measuring eye movements. In cooperation with Chronos Vision GmbH a 200 / 400 Hz 3D Eye Tracker
was developed and is now used in numerous labs throughout Europe, USA and Japan.
In cooperation with the German Space Agency ( DLR)
and Kayser-Threde GmbH
a space-qualified version
of the Eye Tracker was developed and deployed on the International Space Station for
vestibular and oculomotor research experiments.
More recently a 1350 Hz binocular eye tracker has been developed and is marketed through
Chronos Vision GmbH.
-
We perform vestibular and oculomotor testing for normal clinical screening and
in selected cases for differential diagnosis of otolith function.
This work is supported by DLR grants WB 0023 & WB0429.
