Neurotransmitters are also found at the axon endings of motor neurons, where they stimulate the muscle fibers to contract. The first of the neurotransmitters to be studied, acetylcholine, transfers nerve impulses from one neuron to another, where it propagates nerve impulses in the receiving neuron, or from a neuron to a muscle cell, where it generates muscle contractions

Predicting 160 ms into the future without the brain. “A subset of the muscle spindles, called type Ia afferents, fired at a rate that was proportional to the speed of their muscles, but at a time around 160 ms in the future.” https://journals.biologists.com/jeb/article/214/3/iii/33497/MUSCLE-SPINDLES-PREDICT-THE-FUTURE

Body ownership and a new proprioceptive role for muscle spindles ABSTRACT Knowledge of which body parts belong to us is referred to as the sense of body ownership. There is increasing evidence that this important aspect of human proprioception is highly malleable. Research into ownership of individual body parts was stimulated by Botvinick and Cohen’s rubber‐hand illusion (Nature 391,1998, 756), which demonstrated that an artificial body part can be incorporated in one’s body representation and can cause real body parts to be sensed erroneously. Here, we review key studies that have advanced our understanding of the sense of body ownership, including the important role played by multisensory integration and spatiotemporal congruence of sensory signals. We also discuss our recent discovery that body ownership can be induced in response to movement stimuli by signals from a single class of sensory receptor, namely muscle spindles.

Instead, they sense and send information to the CNS about muscle length rate of change of muscle length Biophysical metaphor for: Length, Rate of Change. If our ideas of physics and philosophy implicitly stem from our own body systems, acting as our original map of “what is”, this could certainly be an example of several things in physics, mathematics and philosophy, including a few dualities.
Muscle spindles are too
subthalamic nucleus (STN) / allow or full stop not only of motor but also thoughts; that’s why it feels physically jarring when something interrupts your thinking;; to your brain it’s nearly the same as physically having to stop muscle motions suddenly. [stop running immediately, etc)

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]
