Introversion and Extroversion are associated with a structure in the brain stem called the Reticular Activating System, which regulates the flow of sensory information into the Cortex. An overactive RAS that censors sense data too much is associated with Extroversion while an underactive RAS that lets too much sense data through is associated with Introversion.
Thus the mind of the Extrovert feels starved of sense data and actively seeks more while the mind of the Introvert feels overwhelmed by sense data and withdraws from direct contact so it can process the sense data. This produces the differences described by Jung, Es orient themselves to the outside world, the source of the much-wanted sense-data, while Is withdraw into the inner world of their minds in order to process all the incoming sense-data in peace.
