Notable features are the contrary motion in the ST36 and +6mm impedance readings. Such contrary motion in nearby impedance readings usually indicates that the feature represents a genuine signal which reflects activity in the related organ, rather than artefact of any sort.
The blips on all the plots corresponding with the marker lines may all be movement artefact, introduced when the subject pressed the footswitch with his left foot.
At around 110s, there is a large movement artefact which was caused by the subject deciding to move to tuck the blanket into his right sock, since his shin was feeling chilly, and in previous experiments, this had introduced significant artefact on all the temperature readings.
However, a striking feature of this is that it also includes a spike on the GB meridian, in contrary motion. This “spike” part of the feature is therefore not artefact but is a genuine signal reflecting gallbladder activity. The spike also appears on the ST36 +6mm sensor, but not on the ST36 sensor itself. This is consistent with the placement of the sensors. The feature begins at the GB meridian, influences the sensor 6mm medial to it, and also the ST36+6mm sensor, which was 30mm medial to it, but here the spike is of less magnitude; and does not appear at all on the ST36 sensor, which was a further 6mm medial. This pattern of the impedance at an acupoint, also influencing the surrounding area has been seen on several other experiments in this project.
Note that in Chinese Medicine, it is recognised that the gallbladder enables a person to make decisions. This connection is often seen in clinic today, where a person who has recently been making lots of decisions will often have notable tenderness on the key gallbladder acupoints. Indeed, the subject often feels soreness on the gallbladder meridian on his lower leg, which coincides with periods of heavy thinking and decision making.
The other notable feature in the plots is that there is a considerable amount of “contrary-motion” features on the GB plots, indicating that these genuinely reflect gallbladder activity, rather than being artefact of any kind.
Also, the impedance of the ST36 and the GB meridian show a general rising trend, which in other experiments in this project is associated with increased activity of the related organs. In this case, food was being digested, so this was expected.
The skin temperature readings clearly show the drop in temperature at ST36 and at the GB meridian, relative to the surrounding skin. The skin temperature of any meridian or acupoint is often notably cold to the touch when the associated organ is stressed.
