Incheon National University 2 articles published in JoVE Neuroscience Brain Mapping Using a Graphene Electrode Array Donggue Kim*1, Mingyeong Jeong*1, Elishia Kim1, Gaeun Kim1, Junewoo Na1, Sunggu Yang1 1Department of Nano-Bioengineering, Incheon National University We present a graphene array-based brain mapping procedure to reduce the invasiveness and improve spatiotemporal resolution. Graphene array-based surface electrodes exhibit long-term biocompatibility, mechanical flexibility, and suitability for brain mapping in a convoluted brain. This protocol allows for constructing multiple forms of sensory maps simultaneously and sequentially. Neuroscience Investigating Long-term Synaptic Plasticity in Interlamellar Hippocampus CA1 by Electrophysiological Field Recording Hannnah Tetteh*1, Jihwan Lee*1, Jinho Lee2, Jae Geun Kim3, Sunggu Yang2 1Department of Biomedical Sciences, City University of Hong Kong, 2Department of Nano-Bioengineering, Incheon National University, 3Division of Life Sciences, College of Life Sciences and Bioengineering, Incheon National University We used recording and stimulation electrodes in longitudinal hippocampal brain slices and longitudinally positioned recording and stimulation electrodes in the dorsal hippocampus in vivo to evoke extracellular postsynaptic potentials and demonstrate long-term synaptic plasticity along the longitudinal interlamellar CA1.
