Abstract
Fluorescence Ca2+ imaging enables large-scale recordings of neural activity, but collective dynamics across mammalian brain regions are generally inaccessible within single fields of view. Here we introduce a two-photon microscope possessing two articulated arms that can simultaneously image two brain areas (~0.38 mm2 each), either nearby or distal, using microendoscopes, in awake behaving rodents.
