A neural interface is a device to exchange information with the nervous system.
Signals can be introduced by localised electric stimulation of neurons. And information can be captured by recording the electrical activity of neurons over time.
Interfacing to the central nervous system - the brain and spinal cord - is a major focus of neuroengineering.
Examples are deep brain stimulation to regulate mood disorders, epilepsy and Parkinsons symptoms. As well as the development of the ability to control devices with brain-computer interfaces.

The Utah Electrode Array [1], [2] provides a multichannel interface to the cerebral cortex. Each of the electrodes is individually addressable.
