Curriculum vitae Professor Dr. Horst Bleckmann
We study the functional principles and the peripheral and central mechanisms of information processing within the hydrodynamic sensory systems of fish and crocodiles. In further projects we examine the importance of the lateral line for the locomotion of rheophilic fishes in laminar and turbulent water flow as well as the ability of fishes to detect and discriminate the structure of komplex hydrodynamic stimuli like vortex streets. We are designing artificial lateral lines to improve our understanding of the performance and the filter characteristics of the peripheral lateral line and the develop biomimetic flow sensors. In addition, we are interested in the cognitive capabilities (e.g. visual discrimination, object categorisation, spatial memory, avoidance learning) of cartilaginous fishes and teleosts. While behavorial tests are designed to elucidate the capabilities of selected species in two choice alternative tests and maze experiments, anatomical lesions and histological studies help to identify the neural substrates that are involved in these processes.
