APPLICATION
“All of us have the needs & values of 4 (S/N, T/F) MBTI Temperaments but one is “home base”- which comes naturally, the one we go to when under stress.
We can’t seem to live without it – the one we’re most drawn to & find satisfying (Dominant).
Equally, we dislike one of them, the one we avoid or are suspicious of.” (Inferior)   

MBTI Functions associated with Neocortex Regions:

Si – brain activity reflects background, training & expertise. ‘In the zone’ when reviewing past events, good at recalling info without context or kinship data
– high level of activity in T5 (respect for protocol & social order) when responding to social feedback
– activity in T6 (planning) when considering the future

▪︎ ISTJs & ISFJs are both visual (O1 &/or O2).
ISxJs favor Fp2 over Fp1, while ESxJs do the reverse.

Se – shows “Tennis hop” pattern. Quickly integrates body & sensory info
– has over-all low level cognitive activity (blue areas), allowing quick action response in the moment
– can easily go into ‘the zone’ in a crisis
– often bored : more activity when looking out window than when doing desk work

📈
Ni – (INFJ / INTJ) often shows ‘In Flow’ pattern when attacking new task
– works best when focused on a single Q without distraction (blue)
– strong activity in O1 & O2, the visual areas. like picturing the future
▪︎ Other types only show this pattern when engaged in their specific area of expertise, except Ni-users, who also show it when tackling a new problem

Ne – (ENTP / ENFP) often shows “Christmas Tree” activity
– least likely Types to have ‘In Flow’, unless due to expertise
– uses areas that support imagination (F7), often experience creative HIs
– has
 fast, creative responses, sometimes too much (‘Imaginative Mimic’) 
– hard to get in ‘the zone’, & then only after practicing / internalizing an activity over weeks, months or years

📈
Ti
– sometimes shows ‘Tennis hop’ (ISTP). Least interested in listening
– INTPs tend to quickly stop listening, to assess relevance of what’s being said

neocortex shuts out raw emotions, for objectivity
– 
tend to dissociate when arguing or meeting someone new
– high use of complex logical reasoning areas (F3, F4, P3, P4), which are deep inside neocortex, so can ‘detach’ by being away from visual, auditory & kinesthetic distractions
– engage the 4 areas, as well as Fp1 & 2, when examining a topic from multiple angles, to integrate info into coherent whole 

⚙︎ F3 – derives solutions linearly (ESTPs highest, then INTPs)
⚙︎ F4 – categorizes & defines concepts (INTPs highest, then ESTPs)
⚙︎ P3 – integrates visual-kinesthetic data (ISTPs highest, then ENTPs)
⚙︎ P4 – holistically weighs many pros & cons of uncertain or risky factors (ENTPs highest, then ISTPs)

Te – (ESTJ / ENTP) shows efficient use of mental energy
– relies on 4 key Left side areas (O1, C3, T3, Fp1 = hearing, seeing, recalling, deciding). Tends to not use other areas much, even with tasks that would normally invoke them in others
▪︎ IXTJs are more visual, attentive to tone of voice, & focus on applying details over quick decision-making
• ESTJs more open to brainstorming, & listen intently to authority figures

📈
Fi – (ISFP / INFP) excellent at active listening. EEG is solid bright blue, all parts being in sync
high activity in T3 & T4 (language). Carefully compose speech (content & delivery)
high activity in F8, stimulated by ranking importance
least activity in anterior regions that encourage logic / – relies on left-brained (Fp1) decision-making

▪︎ INFPs will listen deeply for 10 min. & so can get to core of someone’s psychology. Less likely to defend their own views or take action, though when they stop listening, Fp1 gets very bright, from making a strong (or final) decision
• INSPs listen briefly for connection, then move to action (show ‘Christmas Tree’), but more attentive when others withhold info 

Fe – (ESFJ / ENFJ) increased brain activity focused on social responsibility
– active in T3 (diction & grammar) – stimulated by communicating explanations & decisions
– uses F5 a lot, which helps adjust to social feedback
uses Fp1 to suppress emotional impulses from deep in the brain, in favor of mature cognitive responses
– uses Fp2 less, so may suddenly switch from highly composed to very angry
– least activity in visual areas (O1 & 2)

▪︎ ESFJs more left-brained, high activity in C3 & F7
▪︎ ENFJs more right-brained, high in F4 & T4
