Optogenetics is a neuromodulation technique that uses light to control cells in living tissue, typically neurons, that have been genetically modified to express light-sensitive ion channels. This technique has revolutionized neuroscience by enabling researchers to precisely control and monitor the activity of specific neural circuits with millisecond precision.
Some of the emerging trends in optogenetics include the use of optogenetic tools to study neuronal circuits, the use of optogenetic tools to control cell fate, and the use of optogenetic tools to study disease models.
