We know that the gastro-intestinal tract has a wide repertoire of responses to human situations. Everyone knows the sinking feeling on receiving bad news, or the epigastric cramp before a near automobile accident. The intestine is equally responsive to emotional stimuli of lesser degree, and these responses can be easily seen on the fluoroscopic screen.7 Stomach contractions and peristalsis stop at an unpleasant stimulus, and may even be reversed if the unpleasantness is increased. The secretory activity of the stomach is also extremely susceptible to emotional experience. The stomach is indeed one of the most responsive organs in the body, reacting in its spasms and empty-ing and contractions and secretory activity to almost every emotion and sensation. And this is the reason why illnesses of the gastro-intestinal system were the first to be thought of as

• emotion
• reason
• experience
• stimulus
• thought
