31. Sleep promotes quiescence, while walking promotes motor activity. 32. Despite the lack of statistical significance it seems that contact with food provided the most potent stimulus to inducing motor activity. 33. Non-deglutitive motor activity of the oesophagus is usually considered a sign of disordered motility. 34. Recent findings show that, in addition to these well known tertiary contractions, several other types of non-deglutitive motor activity exist, even in healthy subjects. 35. In both instances the stimulus eliciting this non-deglutitive motor activity is continuous or repeated distention of the oesophagus by swallowed or refluxed material. 36. The cells fire these chemicals in pacemaker fashion, keeping the brain alert, enhancing attention and priming motor activity. 37. The receptors are concentrated in the brain regions responsible for motor activity, concentration and short-term memory. |
