Limitations in scanning speed have made it difficult for two-photon imaging to provide accurate temporal information on neuronal signaling. Refinements to random-access scanning using acousto-optic deflectors and an automated algorithm for reconstructing complex spike trains allowed in vivo high-speed optical recording of spiking activity in neuronal populations in the mouse neocortex.
