Optogenetics is a booming multidisciplinary bioengineering technology. It has the characteristic of high spatial-temporal resolution and cell-type specific. It overcomes the disadvantages of traditional methods of the activity control for the cell and organism, and also provides a revolutionary method for the research of neuroscience. The research fields include fundamental research of neural circuit, study and memory research, habituation research, dyskinesia, sleep disorders, parkinsonism, depressive disorder, anxiety disorder etc., and many classic laboratory animal germ line(drosophila melanogaster, nemathelminth, mice, Marmoset, and machin etc.).
Neuroscience is the scientific study of the nervous system. It is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine, genetics, and allied disciplines including philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroeducation and neurolaw. The scope of neuroscience has broadened to include different approaches used to study the molecular, cellular, developmental, structural, functional, evolutionary, computational, and medical aspects of the nervous system.
