The intestinal phase means the phase that concerns the intestines (the gut) which is located after the stomach in the digestion process, so the intestinal phase does not include the stomach.

For example, nucleus accumbens is part of the limbic system and it is involved in reward and pleasure that can make happiness.


Besides that, the precuneus (located in front of the upper portion of the occipital lobe) is involved in feeling happiness. Scientists have shown that there is a positive correlation between the volume of grey matter in the right precuneus and the subject's subjective happiness score.
