Imagine you’re a conductor of a symphony, able to control each individual musician with a flick of your baton. That’s what optogenetics does for neurobiologists – it allows them to manipulate specific neurons using light. By using a combination of genetics and optics, scientists can introduce photosensitive proteins into the neurons and then activate or inhibit their activity simply by shining light on them. This precise and non-invasive technique has shown promising results in understanding neuron functions, unraveling neural circuits, and even developing treatments for various neurological disorders. In this review, we dive deeper into the revolutionary research of optogenetics in the field of neurobiology, exploring its applications in controlling nerve cells, investigating neural circuits, and potentially offering new therapeutic avenues. Get ready for a fascinating journey through the realm of optogenetics and the secrets it unlocks in the intricate world of the brain!
Optogenetic is a technique that combines optics and genetics to control specific neurons. This technique usually uses adenoviruses that encode photosensitive protein. The adenovirus may concentrate in a specific neural region. By shining light on the target nerve region, the photosensitive protein encoded by the adenovirus is controlled. Photosensitive proteins controlled by light can selectively allow ions inside and outside the cell membrane to pass through, resulting in inhibition or activation effects. Due to the high precision and minimally invasive, optogenetics has achieved good results in many fields, especially in the field of neuron functions and neural circuits. Significant advances have also been made in the study of many clinical diseases. This review focuses on the research of optogenetics in the field of neurobiology. These include how to use optogenetics to control nerve cells, study neural circuits, and treat diseases by changing the state of neurons. We hoped that this review will give a comprehensive understanding of the progress of optogenetics in the field of neurobiology.
