Pressure upon certain points puts a stop at times to the convulsion when present, and consequently these points may be called pressure-arresting points. In other cases the convulsions are brought on by pressure on particular points, and these may..be called pressure-exciting points. 1896J. M. Da Costa Med. Diag.
