"Researchers have discovered that a primitive region of the brain responsible for sensorimotor control also has an important role in regulating emotional responses to threatening situations. This region appears to work in concert with another structure called the amygdala to regulate social and emotional behavior.
Georgetown University Medical Center researchers have recently discovered that activation of a primitive brain region, the deep layers of superior colliculus (DLSC), elicits defensive behaviors such as an exaggerated startle, hypervigilance, cowering, and escape. Researchers say it is possible that a prolonged activation of this defense system may lead to emotional disorders.
In a study presented at the 39th annual meeting of the Society for Neuroscience, the GUMC scientists say, in addition to triggering defensive behaviors, the activation of DLSC leads to a decrease in affiliative social interactions. Typically, social interactions are thought to be domain of the amygdala, a region known to work closely with high-level executive structures to regulate emotional processes. The researchers say there is no information about possible interactions between the amygdala and DLSC for regulating social and emotional responses. They decided to try simultaneously activating DLSC while inhibiting the amygdala. In doing so, they discovered that the manipulations cancelled each other out.
"These results suggest that the amygdala and DLSC interact to modulate emotional and social behaviors, either directly, or indirectly by converging on a common target in the brain," says Ashley Decker, a research assistant in the pharmacology department at GUMC, and now a student at the Georgetown University School of Medicine. "The understanding of the functional interaction between these two brain structures is expected to reveal novel targets for therapeutic intervention for post traumatic stress disorder and other anxiety disorders.""

HSP is a anxiety-like state which is about fear. The superior colliculus (DLSC) and the amygdala seems to be involved in these states. Therefore HSP is directly linked to Organic encoding in Neojungian Typology.
The question is, what types have more HSP than others? Probably types with an Organic experience in their first experience. So all types starting with a O experience.

I think abstract association implies a nervous system response that indicates a generalized sensory experience, where we experience emotions and environmental implications collectively, i.e, we feel what others feel, we're aware of how others react, and it bears relevance to us and our sensory experience. Even ADE-HAs and ADP-Las show this experience, and this somewhat makes them relate to HSP, caring for environmental factors and for things that are off-center around them, such as the buzzing of a refrigerator, the chill of a wind, the bark of a dog, or the body language of other people. That's enough to have empathic experiences of others behavioral cues, making you experience someone touching their neck, as if you were the one touching your neck. Concrete association indicates the nervous response is localized to our own body and experience, and we're able to detach from external sensations as a result of high concrete association.
Organic encoding is an indicator of non-semantic experiences of an emotional/sensory nature, for example experiencing instinctual sensations that are hard to explain or verbalize, allowing a broader range of emotions and instinctual sensations to be experienced. Deterministic encoding seems to indicate the experience of sensory input is generally limited or focused towards emotions that are within the semantic range of possibilities, and whilst deterministic users will be affected just as much as organic encoding, they'll be able to ignore emotions that they deem as irrational or without explanation, where organic encoding users will be more frezzled by the sensations they experience. So someone using a harsh tone will affect a person with organic encoding, because they'll be reacting instinctively to the tone, perceiving being attacked, where a highly-semantic person that doesn't consciously associate angry tone with being attacked, will be able to ignore the experience.
Finding a semantic code for an experience is similar to "rationalizing" the experience, giving it a conscious form or category, and things outside the category are "irrational" for a deterministic type.

So to summarize, I'd say HSP needs two criteria to be met:
High HSP requries a person to have a developed generalized/empathic experience of emotions, and a non-verbalized experience of emotions (AO), medium HSP either needs the generalized/empathic experience of emotions (Ax), or the non-verbalized experience of emotions (Ox). Non-HSP need to meet the criteria of localized experience of emotions, and verbalized/rational experience of emotions. (CD)
