The present invention consists of an implantable device with at least one
package that houses
electronics that sends and receives data or signals, and optionally power, from an external
system through at least one coil attached to at least one
package and processes the data, including recordings of
neural activity, and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that are attached to the at least one
package. The device is adapted to electrocorticographic (ECoG) and
local field potential (LFP) signals. A brain stimulator, preferably a
deep brain stimulator, stimulates the brain in response to neural recordings in a closed
feedback loop. The device is advantageous in providing
neuromodulation therapies for neurological disorders such as
chronic pain, post traumatic stress disorder (PTSD), major depression, or similar disorders. The invention and components thereof are intended to be installed in the head, or on or in the cranium or on the dura, or on or in the brain.
