Neuroethology and Electrophysiology of Weakly-electric Fish

During this course neuroethological experiments on weakly electric fish, namely Gnathonemus petersii, an African fresh water fish are being performed. The focus will be on the observation of the behavior of freely swimming animals whose electric discharge signals in the millivolt range are being monitored simultaneously. Our goal is to demonstrate and discuss the basis of bioelectricity by use of simple non-invasive electrophysiological equipment. Besides experiments with a focus on learning how to use the equipment, the students will get the chance to design and perform their own simple experiments. Questions as to the meaning of weak electrical signals for electroorientation and communication will be addressed. The results of the experiments from different groups will be discussed.
