1. A method for characterizing a cell, the method comprising:
- incorporating into an electrically excitable cell an optical actuator of, and an optical reporter of, electrical activity;
obtaining a signal from the optical reporter in response to a stimulation of the cell; and
evaluating the signal, thereby characterizing the cell.

Abstract
The invention provides methods for characterizing cellular physiology by incorporating into an electrically excitable cell an optical reporter of, and an optical actuator of, electrical activity. A signal is obtained from the optical reporter in response to a stimulation of the cell. Either or both of the optical reporter and actuator may be based on genetically-encoded rhodopsins incorporated into the cell. The invention provides all optical methods that may be used instead of, or as a complement to, traditional patch clamp technologies and that can provide rapid, accurate, and flexible assays of cellular physiology.

32. A method for characterizing an interaction between cells, the method comprising:
-
incorporating into a first electrically excitable cell an optical actuator of electrical activity incorporating into a second electrically excitable cell an optical reporter of electrical activity; culturing the first electrically excitable cell and the second electrically excitable cell in proximity to one another; obtaining a signal from the optical reporter in response to a stimulation of the first electrically excitable cell; and evaluating the signal, thereby characterizing an interaction between the first electrically excitable cell and the second electrically excitable cell. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)
