EXECUTIVE brain FUNCTIONING
The Prefrontal Cortex (PFC) manages high-level thinking, emotional regulation & impulse control .  It coordinates focus, planning, decision-making & social behavior – according to internal goals & values.
It provides top-down bias signals** to other brain structures, to guide the flow of activity along neural pathways. (IMAGES….➡️)

**Top–down bias :  Any scene/event contains many different objects or impressions competing for attention. Since the visual system had limited processing capacity, mental choices have to be made to accomplish a task, choosing from among those possibilities. This is resolved in the visual cortex & the complex network in the frontal & parietal cortexes. (More….)

EXP: “A main source of top-down influence may come from neuronal systems which form working memory.”
If you’re looking for something specific (a friend’s face, your car, dinner from a menu ….), the brain pulls up similar images of it from its rolodex of experiences. This is a mental ‘hint’ of what to focus on, with the benefit of allowing you to temporarily ignore anything in the field of vision that’s NOT the object wanted.

IN CHARGE:
⬅️ The brain finishes developing around age 25, although research shows that it can keep refining & shifting throughout our life.  The 20 modules in Nardi’s BRAIN MAP (in part 2) correspond to actual brain anatomy, & the 2 areas behind the forehead are the busy ‘Executives’ (PFC). They help to regulate & synthesize inputs from the rest of the brain – the outermost areas ——> to the deeper limbic system & brain stem.

EXP: Fp1 gets activated when WE –
Show confidence. Stay focused & get organized. Clarify ideas, needs & goals. Make decisions & select among options. Are results-oriented & stay sharp. Screen out distractions & criticism. Evaluate situations according to principles / values. Notice & correct errors.
BUT when overused, can become rigid, closed to new information (“Brain Savvy Leadership“)
🔴 🔵 ⚫️
SAMPLE of 4 MBTI Types
Chart shows uses / purpose for the 16 data points on the scalp (modules), & how these specific Types react.
Nardi said that a very high % of people who tested as the same MBTI Type had near-identical brain patterns.

NOTE – 1st column : Green for LEFT  / Yellow for RIGHT brain

SCANS ⬆️ :
The link between brain responses & Type is statistical, using a network-analysis technique. Images of neural networks indicate long-term wiring from years of habit, which likely support our Type’s preferences. There is activity in other brain areas for each of these 4 scans, not shown, but here the focus is on Blue = highest & Grey = medium activation, the same as the orange / yellow spaces shown above.

Nardi’s comments on the co-owners of “Personality Lingo” :
❤️ MARY M. (“Our True Colors”)
She’s an empathizing, hearing, initiating, improvising, sensing Type.  A “Senior Manager / Connector” N-F style : abstract & conceptual thinking, good with identity, imagination, deductions, metaphors & rapport. Extrovert with most connections in the front.

🔷 Dr. ED R, Family Practitioner – He’s an analyzing, anticipating, linking, reflecting, synching Type.
Introverted Thinker “Back Office / Visual Engineer” style (many connections back of the cortex) – analytical reflective skills, good with facial recognition, recalling facts, narrative memory, reading, number crunching, strategy.

The P4-T6-O1-O2 square – as the base – typically indicates excellent ability at reading body language & facial expression, often seen in therapists, who understand people in a Right-brain way.

📌 VH‘s use of his Nardi scan
CHART  – an INFJ who Nardi identified as most like an ENFP. ➡️
He’s made his own set of comparisons, concluding that : “I’m an INFJ lacking solid activity in one rather crucial region of self-regulation (F2), causing my ADD, as well as my lean toward an ENFP way of self-expression, despite my INFJ thought-processes.
This also explains why I can come off like a Type 8, since low activity in this area can also create a certain degree of bravado & intensity. (MORE….) 2/2019

CONSCIOUSNESS
⬅️ JUNG described aspects of our Psyche = systemic, dynamic, narrative, indefinite….= as having many contradictions, yet in combination they make each of us unique.

⬇️ Here Nardi’s scans show the different intensities of brain activity between the ‘normal’ waking state & a quiet ‘meditative’ state – which shows frontal brain activity mostly missing (see posts “Maslow: Transcendence“…. )
