“…The effect of Area 6 lesions on reflexive grasping was noted in monkeys by Richter and Hines (1932) and has been confirmed by Fulton, Jacobsen, and Kennard (1932); Penfield and Welch (1951); Travis (1955); Denny-Brown (1966);and Goldberger (1972). Observations of this in human patients are abundant (Addie & Critchley, 1927;Freeman & Crosby, 1929;Davis & Currier, 1931;Walshe, Robertson & Graeme, 1933;Kennard, Viets & Fulton, 1934;Penfield &Jasper, 1954;Luria, 1973).…”
