To further our understanding of how neural circuits function, we need tools that can collect simultaneous measurements from large populations of neurons involved in a common neural computation and provide precise functional modulation. Current optical imaging in awake animals expressing calcium indicators provides spatial and temporal precision, but limitations include small fields-of-view (encompassing single brain regions) and head-fixation requirements that prevents naturalistic behavior. Welle and Gibson propose an optical interface that uses novel hardware and computational strategies to allow for fast 3D-imaging (3D-FAST), precisely-patterned optogenetic stimulation, and closed-loop recording in freely-moving animals. They will test the technology in rodents and record from and modulate thousands of neurons to lay the ground for additional behavioral experiments in untethered animals.
