For example, in an embodiment, an implant device may comprise a plurality of fibers adapted to receive electrical signals, optical signals, or both electrical and optical signals from neural signals of the brain tissue and to transmit signals, to provide stimulation of the brain tissue, and a controller to receive signals, determine direct neural connections by analyzing waveforms and propagation delays of the received signals, recognize at least one dead or non-functional neuron and determine direct neural connections affected by the at least one dead or non-functional neuron, and forward neural signals around the at least one dead or non-functional neuron by recording the received signals from one side of the at least one dead or non-functional neuron and transmitting the recorded signals to stimulate an other side of the at least one dead or non-functional neuron.
