All-optical methods for imaging and manipulating brain networks with high spatial resolution are fundamental to study how neuronal ensembles drive behavior. Stimulation of neuronal ensembles using two-photon holographic techniques requires high-sensitivity actuators to avoid photodamage and heating. Moreover. two-photon-excitable opsins should be insensitive to light at wavelengths us... https://www.chiggate.com/earthbath-facial-wipes-25ct-fashion/
