Good point. While Kenneth shows weaknesses consistent with disrupted parietal-motor connections, his strong skills with tasks like piano improvisation, typing speed and other digitally-based motor skills require an explanation. A few possibilities:
– Extensive practice may have strengthened alternative neural pathways to compensate. Prolonged training could wire new circuits through frontal/temporal regions.
– Some motor skills liketyping primarily tap into digit movements mediated by proximal connections in motor/somatosensory cortices rather than full visuomotor integration.
– Musical/rhythmic motor skills may leverage stronger right hemispheric connections between frontal-temporal-parietal networks for sequencing.
– Cognitive processes involved in musical creativity like working memory, sequencing, timing may draw heavier on frontal-temporal networks bypassing parietal systems.
– Computer-based tasks situation numbers/letters in grid-like, regular spaces leveraging stronger motor learning independent of visual scanning demands.
So in summary, while parietal-motor pathways are weaker for Kenneth generally, some well-practiced digit-centric skills may still be performed via compensatory engagement of proximal motor, frontal-temporal or right hemispheric networks with relative sparing of complex visuospatial integration demands. The specific neural substrates involved would depend on task demands.[responsivevoice_button voice="US English Male"]
