TY - JOUR T1 - Wide field-of-view, multi-region two-photon imaging of neuronal activity <em>in vivo</em> JF - bioRxiv DO - 10.1101/011320 SP - 011320 AU - Jeffrey N. Stirman AU - Ikuko T.

Temporally multiplexed excitation pathways can be independently repositioned in XY and Z to simultaneously image regions within the expanded field of view. We used this new imaging system to measure activity correlations between neurons in different cortical areas in awake mice. ER -
