Inhibition of cortical neural networks using infrared laser.

abstract：:We developed an optical imaging method based on a feedback principle in which the specific scan pattern is adapted according to the shape of the sample. The feedback approach produces nanometer-resolved 3D images of very small and moving features in live cells in seconds. We show images of microvilli in live cultured ...
