Microlesion

In the field of Space exploration and nuclear physics, a microlesion refers to a microscopic lesion of heavily damaged cells in the tissues of the Central nervous system. Micolesions are primarily caused through exposure to High Enery Nuclei (HZE) radiation, a typical evironmental condition of unsheilded cosmic rays in deep space, or accidental occupational exposure during high energy nuclear physics experiments.^[1]

In the field of neurology, a microlesion may also refer to the formation of a small blisters in the brain following the implantation of an electrodes. This is a typical condition following the surgical treatment of Parkinson's disease and other neurologic diseases requiring the implantation of electrods as a form of treatment.
