SIngle sided profound deafness can also mean: * Trouble paying attention to what people are saying: “evasive” behaviour. * Misdiagnoses as ADHD * Seeming lack of awareness of other people’s personal space and moods since brain is hyper-focused on deciphering auditory information in lieu of non-verbal social cues. * Appearance of anxiousness even in low noise situations * Jumpiness * Chronic interpersonal communication difficulties due to inability of brain to isolate or beam form sounds and voices of other individuals

Now, superior Right SFG: Conscious attempts to self-control emotion happen here. “Significance statement: Individuals vary in impulse control. However, the neural bases underlying individual variation in proactive control of impulsive responses remain unknown. Here, in a large sample of young adults, we showed that activation of the right superior frontal gyrus (SFG) during conflict anticipation is positively correlated with the capacity of inhibitory control and negatively with motor urgency in the stop signal task. Importantly, activity of the right SFG mediates the counteracting processes of inhibitory control and motor urgency across subjects. The results support a unique role of the right SFG in individual variation in cognitive control. ”

I) ok. impairments in: a) left Heschl’s gyrus, b) right supramarginal gyrus, and c) left superior frontal gyrus. ————– so what are they good for? ——————- a) left Heschl’s gyrus: That’s the auditory cortex on the left side. Left ear deaf, so that area would not function. No cause effect here but a pairing. With one working, the other won’t either. b) Right SMG: “The right-hemisphere supramarginal gyrus appears to play a central role in controlling empathy towards other people. When this structure isn’t working properly or when having to make very quick judgements, empathy becomes severely limited.” also: _Right Supramarginal Gyrus Is Crucial to Overcome Emotional Egocentricity Bias in Social Judgments_ Oh my! So _possibly_) in a stressful moment / panic moment, I may neglect the needs of another – and linked to left ear deafness. Fascinating if so. I know if there’s a split second decision I may very well “drop the ball” – not intentionally but because there’s not a “there” there sometimes until afterwards – and this partially confirms/gives some credence to this intuition of myself. That is, I don’t like it but I know it’s not something that I can wish away but instead work around. c) left superior frontal gyrus “(i) the lateral and posterior portion of the left SFG is a key component of the neural network of WM; (ii) the participation of this region in WM is triggered by the highest level of executive processing; (iii) the left SFG is also involved in spatially oriented processing” Ok, so crucial in complex tasks – the worse it functions, the worse complex tasks are handled in working memory -BUT- executive (willpower as it were I guess) can overcome its malfunction if needed.

Seeking more ‘trait from birth’ connections: quick focus on “LEFT EAR total deafness” to see what likely plastic changes occurred: this is a checklist to go down and see _possible_ connections. “When compared with the right-sided hearing impairment group, the left-sided hearing impairment group showed significantly higher fALFF values in the left superior parietal gyrus, right inferior parietal lobule, and right superior frontal gyrus, whereas it showed significantly lower fALFF values in the left Heschl’s gyrus, right supramarginal gyrus, and left superior frontal gyrus. In the left-sided hearing impairment group, paired brain regions with enhanced FC were the left Heschl’s gyrus and right supramarginal gyrus, left Heschl’s gyrus and left superior parietal gyrus, left superior parietal gyrus and right inferior parietal lobule, right inferior parietal lobule and right superior frontal gyrus, and left and right superior frontal gyri. In the left-sided hearing impairment group, the FC of the paired brain regions correlated negatively with the duration and pure tone audiometry were in the left Heschl’s gyrus and right supramarginal gyrus. ”

Muscle pattern training compensates [this relates to the ADHD-like symptoms in preterm] YES! Motor skills FULLY MEDIATED the association between preterm birth and P300 but not cardiovascular training. That is: LEARN MUSCLE SKILLS (like playing the piano, drawing, sports). (Now what about P300 _initiation_ > response?) “Very preterm birth was associated with impaired response inhibition.” • Impaired behavioral performance was linked with decreased P300, but not N200. • Motor skills fully mediated the association of preterm birth and P300. • Cardiorespiratory fitness did not contribute to this mediation. • Improving motor skills might promise the reduction of cognitive control deficits. N200-P300 complex. Doesn’t differentiate between subtypes (ADHD vs inattentive ADHD _however_ as this isn’t about “which ADHD is more similar to very preterm/vlbw symptoms? (ADHD-I) but about preterm. The “Go” of P300 internally generated intent has issues too in preterm > adhd or adhd-i – I’ll see who else does. But this study right here is big; it confirms motor compensation for inhibition issues]
