Research Project in the lab:

Otto’s research focuses on neuronal circuits in the mammalian auditory brainstem, particularly the circuits that are located in the superior olivary complex. Otto studies the anatomical source of well-timed inhibition to a predominant sound localization circuit, the medial nucleus of the trapezoid body (MNTB). Methods include immunohistochemistry, confocal as well as two-photon microscopy, in-vitro electrophysiology and neuronal tracing techniques.
Otto is also experienced with genetic and molecular approaches. During his Diploma-Thesis at the University of Munich, he assembled a genetic construct that enabled him to study the sound localization pathway in the auditory brain stem with light-sensitive ion channels (optogenetics).
