Monsters in stories have rules. (Real-world monstrous humans may not.) I'm working out how my fictional homunculi are going to work. A public post.

"we find that the classic homunculus is interrupted by regions with distinct connectivity, structure and function, alternating with effector-specific (foot, hand and mouth) areas." This suggests "that M1 is punctuated by a system for whole-body action planning. two parallel systems intertwine, forming integrate–isolate effector-specific regions for isolating fine motor control and a system for integrating goals, physiology & body movement."

How Our Team Overturned the 90-Year-Old Metaphor of a 'Little Man' in the Brain Who Controls Movement - Scientific American
In my first neuroscience course at Columbia University, I learned about the #homunculus. This “little man” is depicted as an upside-down representation of the human body moving from toe to head in a portion of the cerebral cortex that controls movement. Wilder Penfield, the trailblazing Canadian-American neurosurgeon, created the homunculus metaphor after mapping areas of the human brain by using direct electrical stimulation in awake patients in the 1930s.
From this work, a nurse working with Penfield created one of science’s most iconic illustrations. It shows the homunculus stretched out over the brain’s surface, a small body with enlarged mouth, hands and feet, each part exaggerated in proportion to the amount of neural real estate occupied.

A point that I think is frequently missed in the discussion surrounding the new homunculus paper (https://doi.org/10.1038/s41586-023-05964-2) is that even Penfield himself said not to take his homunculus literally! And in fact we've known for quite some time that M1 in primates and rodents doesn't map solely to single parts of the body, but instead maps to actions too. See this great review from 2016 - https://doi.org/10.1016/j.tics.2015.10.008

A classic, updated: Penfield's homunculus revisited. The authors propose an interrupted homunculus, as an integrate–isolate model of action and motor control.
"A somato-cognitive action network alternates with effector regions in motor cortex"
Gordon et al. 2023
https://www.nature.com/articles/s41586-023-05964-2Let's hope it passes the test of time, because Penfield used electrodes, whereas this new work is with #fMRI.

Mind-Body Connection Is Built Into Brain
Brain areas that control movement are plugged into networks that orchestrate thinking and planning, and control involuntary bodily functions. The findings provide a link between the body and the “mind” in the brain’s structure.

YES. @jamesmharrison reminded me that "Inhibition is something that we DO".
But to tease apart dynamics of goal-directed activation amidst goal-directed suppression... especially when the goal may be unconscious or habitual in one instance, or skilled and volitional in another?
This new preprint may have the methodology needed to tease these things apart - "A mind-body interface alternates with effector-specific regions in motor cortex" 👇 https://www.biorxiv.org/content/10.1101/2022.10.26.513940v1
