Initial claim: I am an engineer, not a doctor
Ever heard of the locus ceruleus ? It is one area in the human brain that could be connected to the origin of Extroverted Intuition. I am deliberatly excluding introverted Intuition cause I am following the premise that the definition of Ne means to "connect the dots".
Said area becomes active when our brain notices something out of the ordinary. So lets say you are unspectaculary sitting in class or a meeting, someone is talking with a monotome voice and suddenly someone drops a glass bottle. You'll get an immediate adrenaline rush. Said area in the brain is said to be the sensor of the occurence.
Now in further studies they examined the effects of LSD and mescalin in controlled dosages on the LC. Here's an excerpt:
If you now think about the connection here: there are many drugs on the market which give you a "good feeling", so which manipulate your neurotransmitter levels. Only a few of those are called psychoactive, which means that people using the stuff start to think they are having a heightened awareness of their surroundings or a deeper understanding of the being and emotions of other people. The LC happens to be the principal site for brain synthesis of the neurotransmitter noradrenaline. I think thats the one peaking when you smoke pot.
So could that LC be a main driver for Ne ? What do you think, bogus ?!
Here's some music for pondering:
