A method of treating neurological deficit in which the brain area affected is focally and precisely stimulated by the transient insertion and subsequent removal of a micro-needle. This insertion and subsequent removal of the micro-needle induces endogenous stem cells to proliferate, migrate and promote the brains self-repair mechanisms. The micro-needle stimulation causes the birth of new neural cells within the brain as well as mobilizes bone marrow derived cells with a neuronal phenotype to migrate to the site of stimulation to repair and replace damaged neural cells. By repairing and/or replacing injured or dead cells, this approach will slow down the degenerative course of the disease and may result in reversal of symptoms.
