Prof. Dr.-Ing. Andreas Bahr: Brain Signal Acquisition with Miniaturized Electronic Systems for the Investigation of Local Neural Networks

Institute of Electrical Engineering and Information Technology, Kiel University

In this talk, I will exemplify how advancements in the design of integrated sensor electronics enable new kinds of biomedical signal analysis:
In neuroscience research the development of the brain and the treatment of diseases like certain forms of epilepsy are analyzed with genetic mouse disease models. For the special case of the recording from neonatal mice (2-3 cm, 3-5 g) an implantable system has been developed, that enables chronic recordings. To achieve this, an application specific integrated circuit (ASIC) has been developed in an advanced 130 nm CMOS technology. Moreover, an implant and a recording system for live view of neural data have been presented. The functionality of the integrated circuit and the suitability of the implant system have been confirmed with in-vivo experiments with adult and 12 days old mice.
