The fathers of gastroenterology clearly recognised the relationships
between the brain and gut. In his classic studies of the control of
gastric secretion conducted on his subject Tom with a permanent gastric
fistula,2 Stuart Wolf found that emotional state affected
secretion and that mucosal blood flow, measured by a simple thermistor,
altered in parallel.3 Similar relationships between rectal
mucosal blood flow and psychological state were also reported by
Almy.4 In his now classic "hoax" experiment, he
