Abstract

Optogenetics is an innovative technology that uses light to control neuron cells. In the rapid synthesis of light-sensitive opsins, significant advances have been made to understand the links between neuronal activities and behavior in healthy and diseased brains over the last few years. This technique allows researchers to selectively activate or inhibit specific neurons with high temporal and spatial resolution, offering unprecedented insights into brain function, circuit dynamics, and neurophysiological disorders. However, challenges such as light scattering, thermal effects, and power efficiency remain key considerations in optimizing these technologies. This review explores the latest advancements in optogenetic stimulation methods, comparing different light delivery approaches in terms of efficiency, biocompatibility, and practical implementation. Additionally, we discuss the limitations associated with current techniques and highlight potential future directions, such as improved opsin engineering, enhanced light penetration strategies, and the integration of wireless optogenetics for seamless in vivo applications. With continuous technological refinement, optogenetics is poised to further enhance our understanding of neural circuits and drive novel therapeutic interventions for neurological disorders.
