Optogenetics is a technique in neuroscience that combines genetics and optics to control and monitor the activities of neurons in freely behaving animals. This is achieved by introducing light-sensitive proteins (like channelrhodopsins) into specific neurons. When illuminated with light of a certain wavelength, these proteins can activate or inhibit the neurons, allowing precise control of their activity. This method is distinguished by its high temporal precision, enabling researchers to manipulate neuronal activity in sync with the fast-paced physiological processes in the brain. Optogenetics has revolutionized the study of neural circuits and behaviors by providing a direct method to probe the causal relationships between neural activity and behavior.
