optogenetics limitations

Optogenetics, medicine and psychiatry ... most important, do not provide deep insight into the diseases, only highlighting (as do the patients) our limitations. The final goal of artificial intelligence (AI)—that a machine can have a type of general intelligence similar to a human’s—is one of the most ambitious ever proposed by science.In terms of difficulty, it is comparable to other great scientific goals, such as explaining the origin of life or the Universe, or discovering the structure of matter. Optogenetics tools can be broadly classified based on their functions into two groups: Actuators are genetically-encoded tools for light-activated control of proteins; e.g., microbial opsins and optical switches; Sensors are genetically-encoded reporters of molecular signals; e.g., calcium indicators; In this overview, we will focus on the common actuators used in optogenetics.
