Bleichner1,2 1Neurophysiology of Everyday Life Group, Department of Psychology, University of Oldenburg, 2Research Center for Neurosensory Science, University of Oldenburg Presented here is the procedure for using the c-grid (ear-electroencephalography, sold under the name cEEGrid) for recording brain activity in and beyond the lab for extended durations. This protocol describes how to set up these arrays and how to record brain activity using them.

VNS leads to antidepressive and antisuicidal effects and quality of life improvements. This protocol offers a step-by-step guide to managing and adjusting a vagus nerve stimulator for efficient treatment of TRD. Neuroscience Electrophysiological Characterization of GFP-Expressing Cell Populations in the Intact Retina Mark Pottek1, Gabriel C. Knop1, Reto Weiler1, Karin Dedek1 1Department of Neurobiology, University of Oldenburg This article depicts the recording of individual cells from fluorescently tagged neuronal populations in the intact mouse retina. By using two-photon infrared excitation transgenetically labeled cells were targeted for patch-clamp recording to study their light responses, receptive field properties, and morphology.
