Claim 0:
1. An apparatus for electrical brain stimulation comprising:
a plurality of electrodes for generating electrical activity in a cortex of a person, the cortex having pre-identified crucial neural nodes associated with a selected brain function and including healthy cortical tissue and damaged and/or partially damaged cortical tissue, wherein the damaged cortical tissue includes damaged neural cells and the partially damaged cortical tissue includes partially damaged neural cells,
the healthy, the damaged and/or partially damaged cortical tissue each having at least one parameter of cortical waves, wherein a value of the at least one parameter the damaged and/or partial damaged cortical tissue is different from a value of the at least one parameter of the healthy cortical tissue, the at least one parameter being one of cortical wave propagation speed, amplitude and frequency,, the plurality of electrodes including electrodes for emitting stimulation electrical signals into the cortex and measuring electrical cortical waves,, and the plurality of electrodes being designed to emit stimulation electrical signals in at least part of the healthy cortical tissue and the damaged and/or partially damaged cortical tissue, wherein at crucial neural nodes;
a processor communicating with the plurality of electrodes and configured to:
evaluate the at least one parameter of cortical waves between at least a first electrode and at least a second electrode corresponding respectively to a first pre-identified crucial neural node and a second pre-identified crucial neural node in the cortex based on the electrical cortical waves measured by the first electrode and the second electrode between the first pre-identified crucial neural node and the second pre-identified crucial neural node, the first pre-identified crucial node and second pre-identified crucial node being situated such that a rectilinear line joining the first pre-identified crucial node and the second pre-identified crucial node crosses the damaged and/or partially damaged cortical tissue;
compute in real time, stimulation signals required to maintain the at least one parameter of cortical waves in a predetermined range between the first electrode and the second electrode and apply the computed stimulation signals to the plurality of electrodes.
