Yes, insofar as many reflexive actions, enervation and fiber recruitment thresholds respond to training, such that they “remember“ actions you have performed many times before. There are many clusters of nerves throughout the body called ganglia that are responsible for low-latency control of various functions that would entail too much delay when controlled entirely by the brain.
Generally, the minimum input-process-activation turnaround time of the brain is about 4 hz (240-250 ms) which is too slow for many applications of motor function. But the “co-processing” allowed by the extended nervous system enables the body to, with practice, execute far more rapid and complex action sequences in response to local stimuli. Some actions can be triggered and completed before a signal even makes it to the brain.
I would guess there’s an upward slope of young contributors that reduce significantly at post-grad and early career ages (e.g. early-mid-twenties) followed by another upward gradient on a 5-10 year delay that peaks in the late 30s then falls somewhat linearly up to 60s.
The median age of the younger/learning cohort might be 19 and falling. The median age of the established developer cohort might be mid-40s and climbing.
