Abstract
A method for measuring the activity of one or more excitable cells, such as neurons, in a target tissue is provided. The present method may include measuring the activity of individual, selected excitable cells by projecting one or more three dimensional (3D) multi-focal laser light patterns into a target tissue containing excitable cells adapted to emit cellular electrical activity—sensitive fluorescence, to generate a multiplexed 2D diffraction pattern of fluorescence emitted by the neurons, and resolving the multiplexed 2D diffraction pattern. Also provided herein is a system configured to perform the present method, the system including a microscope configured to project one or more 3D multi-focal laser light patterns into a target tissue using a spatial light modulator and a mirror galvanometer, and a microlens array and an image detector to record individual and multiplexed 2D diffraction patterns of light emitted from the target tissue.
