These implants can be used for a variety of purposes, from controlling neurological diseases to enhancing cognitive and sensory abilities. They are designed to interact directly with brain tissue, enabling two-way communication between the device and the brain.

Brain implants work through a combination of sensors, electrodes and electronic circuits. They are designed to detect and record brain activity, stimulate specific areas of the brain, or even replace lost functions. For example, in cases of paralysis, a brain implant can be used to transmit signals from the brain to artificial limbs, allowing a person to control prosthetics with their mind.
These implants are also being studied to treat conditions such as Parkinson's and epilepsy, where they may help regulate abnormal neural activity.
