Temporal focusing (TF) multiphoton systems constitute a powerful solution for cellular resolution optogenetic stimulation and recording in three-dimensional, scattering tissue. Here, we address two fundamental aspects in the design of such systems: first, we examine the design of TF systems with specific optical sectioning by comparatively analyzing previously published results. Next, we develop a solution for obtaining TF in a flexible three-dimensional pattern of cellmatched focal spots. Our solution employs spatio-temporal focusing (SSTF) in a unique optical system design that can be integrated before essentially any multiphoton imaging or stimulation system.
