Topic: 3D functional maps

Functional ultrasound imaging (fUSI) can record neuronal activity down to 20 mm depth in the brain, at finer resolution than functional magnetic resonance imaging. We developed an acquisition add-on, analysis and visualization pipeline that allows efficient identification of anatomical and functional layout of the brain in 3D. Leveraging the high signal quality of fUSI, we asked whether the acquisition of multi-cm 3D functional maps can be made compatible with chronic anesthetized experiment design. Since availability of large-brained species is low and their behavioral training can be prohibi
