JUNGIAN COGNITIVE FUNCTIONS ARE REALLY NEUROTRANSMITTERS
Dopamine (Ne) is all about exploration, novelty, and active engagement with the world. It’s testing, experimenting, seeing what works, and staying open to multiple perspectives in real time. It’s "what if" thinking, bouncing between ideas, trying them out, and learning through trial and error. This is why the dopamine pathway is short and reactive, driving people to act quickly and be highly responsive to stimuli.
Acetylcholine (Ni) is much more about conception, depth, and refinement. It’s about filtering through possibilities, refining, and finding the most efficient path. This is more about a long-term vision, where you discount distractions and focus on what’s likely to work based on deep internal understanding. Like Ni, acetylcholine works with refined material, builds on past knowledge, and strives for clarity over time. Quality control over quantity. The pathway is longer, as it requires more time for reflection and synthesis.
Norepinephrine (Se) = Sensory Engagement / External Stimulation: Norepinephrine is often about stimulation, arousal, and action in the present moment, which matches Se's focus on immediate sensory input and the world outside. Se engages directly with external stimuli, maximizing the sensory experience—seeing, hearing, touching, and reacting to what's right in front of them, seeking novel or impactful experiences. Norepinephrine similarly drives people to engage with their surroundings, often seeking intensity and excitement. Both want to be in the moment and responsive to the environment.
GABA = Si (Introverted Sensing): GABA is an inhibitory neurotransmitter, meaning it calms down neural activity and contributes to a sense of stability, relaxation, and grounding. This is highly similar to Si, which is about internal sensory recall, stability, and creating a grounded mental state based on past experiences. Just like Si helps us process and stabilize memories and experiences, GABA contributes to calmness and internal balance.

Ooops. Clickbait. Only the perceiving functions can be directly associated with neurotransmitters but here is why:
Perceiving functions (Ne, Ni, Se, Si) are more fundamental in terms of information gathering and conceptualizing because they deal with raw data, sensory input, and ongoing experience. These are processes that happen almost automatically and are more closely tied to the REACTIONS of the brain to immediate stimuli, which is where neurotransmitters like dopamine, norepinephrine, GABA, and serotonin come into play.
Judging functions, on the other hand, are higher-order, more abstract, and deal with organizing, categorizing, and deciding how to act on the information the perceiving functions gather. These processes tend to be more cognitive, involving more logical, computational thinking (yes, fi too!), which requires less direct chemical input and is mediated by higher-level brain areas like the prefrontal cortex. They are more internalized, less reactive to real-time input, and more about evaluating and controlling the data.

But hey! If you really twist my arm, I could associate Fi with serotonin and Fe with oxytocin.
When it comes to Te and Ti, all I can think of is the lack of serotonin and oxytocin. You lack love, you are less moody, you think more robotic, sticking to the facts as opposed to idealistic or personal or communal values.
