Abstract

Within the scope of the project, it is aimed to make a system definition of multi-sensory integration in zebrafish. For this purpose, the change of rheotaxy behavior in zebrafish in perceptual salience and multisensory integration experiments was examined. In order to carry out these experiments, a special experimental setup that allows the eye and lateral line organs of a zebrafish that can move freely during rheotaxy to be stimulated with independent visual and vibrational signals has been produced in this project.

As a result of the project, the frequency responses of the transfer functions assigned by the central nervous system to visual and vibrational signals during sensory integration were estimated using sensory contrasts. Obtaining these transfer functions enabled the identification of the filtering mechanism used by the brain during multimodal sensory integration.
