A neurological control system for modulating activity of any component or
structure comprising the entirety or portion of the nervous system, or any
structure interfaced thereto, generally referred to herein as a "nervous
system component." The neurological control system generates neural
modulation signals delivered to a nervous system component through one or
more intracranial (IC) stimulating electrodes in accordance with treatment
parameters. Such treatment parameters may be derived from a neural
response to previously delivered neural modulation signals sensed by one
or more sensors, each configured to sense a particular characteristic
indicative of a neurological or psychiatric condition. Neural modulation
signals include any control signal which enhances or inhibits cell
activity. Significantly the neurological control system considers neural
response, in the form of the sensory feedback, as an indication of
neurological disease state and/or responsiveness to therapy, in the
determination of treatment parameters.
