Transparent graphene implant for deep brain imaging and optogenetics

Thu, 05/24/2018 - 21:25
Although advances in optical technologies such as multi-photon microscopy and optogenetics have revolutionized researchers' ability to record and manipulate neuronal activity, integration of optical modalities with electrical recordings is challenging due to generation of light-induced artifacts. In new work, scientists report a transparent graphene microelectrode neural implant that eliminates light-induced artifacts to enable crosstalk-free integration of 2-photon microscopy, optogenetic stimulation, and cortical recordings in the same in vivo experiment.
