Neural activity control

Definition

Neural activity control refers to the ability to manipulate and modulate the activity of neurons within the nervous system, which can have significant implications for both research and therapeutic applications. This control can be achieved through various methods, such as electrical stimulation or optogenetic techniques, allowing for targeted modulation of neuronal behavior. The potential applications in neuroprosthetics highlight the significance of this term, especially in developing devices that can restore or enhance neurological functions.
