Stimulate refers to the act of enhancing or increasing activity in specific areas of the living human brain through various methods such as electrical or magnetic stimulation. It aims to activate neurons and increase neural firing.
DBS involves surgically implanting electrodes into specific brain regions to deliver electrical stimulation, often used for treating movement disorders like Parkinson's disease.
Optogenetics: Optogenetics is a method that uses light-sensitive proteins to control neural activity. By genetically modifying neurons, researchers can use light pulses to stimulate or inhibit specific areas of the brain.
