The robot scales up the patch clamp single cell recording technique to four simultaneous channels, with seal success rates for two-photon targeted and blind modes of 54% and 67% respectively. In 50% of targeted trials (where specific cells were required), at least 2 simultaneous recordings were obtained. For blind mode, most trials yielded dual or triple recordings. This robot, a milestone on the path to a true in vivo robotic multi-patching technology platform, will allow numerous studies into the function and connectivity patterns of both primary and secondary cell types.Competing Interest StatementThe authors have declared no competing interest.
