MBTI & Nardi : Brain ACTIVITY (#2)


PREVIOUS: Nardi – brain activity #1

SITE: NeuroScience & Type

EXECUTIVE brain FUNCTIONING
The Prefrontal Cortex (PFC) is responsible for cognitive control, supervisory attention, orchestrating thought & action 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….➡️)

*Topdown 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, 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, though as research shows, it can keep refining & shifting throughout our lives.  The 20 modules in Nardi’s BRAIN MAP 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. Be 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 6 MBTI Types
Chart shows uses / purpose for the 16 data points on the scalp (modules), & how these 4 MBTI Types react.
Nardi said that a very high % of people who tested as the same MBTI Type had near-identical brain patterns.
NOTE – Modules in 1st column: Green for LEFT brain / Yellow for RIGHTan

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.

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

🔷 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 indicate excellent ability at reading body language & facial expression, often seen in therapists, who understand people in a Right-brain way.

One person’s use of their Nardi scan
CHART was included in a post from VH, an INFJ who Nardi identified as most like an ENFP. ➡️
VH 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. (“See what I did there? Brought thread back to EnneaTypes. Clever. I has it.)” (MORE….2/2019

CONSCIOUSNESS
⬅️ JUNG described aspects of our Psyche, which is systemic, dynamic, narrative, indefinite…. as having many contradictions, yet in combination it’s what makes 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“…. )
