Dear friends and colleagues. Does anyone have any opinions, or know of any studies, regarding the best material (& placement) to use for in vivo electrophyisological Studies? In particular, when recording ECoG potentials? Ideally, needs to be stable, biocompatible, and in a perfect world, non-invasive.... I’m afraid I’m not aware of much literature on this hugely important topic and I would hugely appreciate any help anyone can offer.
