“…For example, this region is the site of the physiological 'brake' on gastric motility (Thomas, 1957) and secretion in man (Griffiths, 1936;Shay, Gershon-Cohen, and Fels, 1942;Gillespie, 1959;Ksster and Rune, 1963;Johnston and Duthie, 1964, 1969. The secretory inhibition probably has both a nervous component (Code and Watkinson, 1955 ;Iggo, 1957;Sircus, 1958;Duthie, 1966, 1969) and a humoral component (Woodward, Lyon, Landor, and Dragstedt, 1954;Greenlee, Longhi, Guerrero, Nelsen, El-Bedri, and Dragstedt, 1957 ;Andersson, 1960Andersson, , 1963Andersson, , 1969Kamionkowski, Grossman, and Fleschler, 1964;Wormsley and Grossman, 1964;Johnston and Duthie, 1966). Inhibition of motility is also neurohumoral in nature (Thomas, 1957).…”
