Although "gut feeling" is a cliché in English parlance, there are neuro-physiological basis for registration of emotions in the gut. Control of the gastro-intestinal (GI) tract is by an integration of neuro-hormonal factors from the local myogenic to the central nervous system. Gastric contractile activity, which is responsible for the motor properties of the stomach, is regulated by this integrated complex. Signatures of the activity include gastric electrical activity (GEA) and bowel sounds. GEA has two distinct components: a high-frequency spike activity or post depolarization potential termed the electrical response activity superimposed on a lower frequency, rhythmic depolarization termed the control activity. These signatures are measured in the clinic with contact sensors and well understood for diagnosis of gut dysmotility. Can these signatures be measured at standoff and employed for purposes of biometrics, malintent and wellness assessment?
