Abstract
Recording neuronal activity throughout the brain with high temporal and spatial resolution may be a critical step in understanding how the brain works. Task-based approaches allow intelligent trade-offs between resolution, speed, and signal. I will describe projective two-photon imaging methods that leverage the spatiotemperal sparseness of neural activity and use holographic multiplexing, and statistical source separation create capable platforms for high-performance imaging with single cell resolution. Similar holographic platforms can also be used to activate ensembles of neurons with single cell precision, and I will describe recent efforts to improve targeting and control in awake behaving animals
