A neurochip is a chip (integrated circuit/microprocessor) that is designed for the interaction with neuronal cells.

[edit] Formation
It is made of silicon that is doped in such a way, that it contains EOSFETs (electrolyte-oxide-semiconductor FET) that can sense the electrical activity of the neurons (action potentials) in the above-standing physiological electrolyte solution. It also contains capacitors for the electrical stimulation of these cells.
[edit] Applications
Present applications are neuron research. Future applications (still in the experimental phase) are retinal implants or brain implants.
[edit] What it is not
A cochlear implant is not a neurochip because it only contains electrodes that stimulate the auditory nerve. Instead, a cochlear implant is more commonly referred to as a neuroprosthesis.
