“the results suggest that for overlearned sequences the pre-SMA is primarily concerned with the initiation of a sequence or sequence chunk and the role of the pre-SMA in sequence initiation is only discerned when subjects must retrieve the sequence from memory as a superordinate set of movements without the aid of a visuomotor association.”
“The pre-SMA does not have a general role in selecting or executing all movements, rather it seems to be concerned with the organization or selection of superordinate sets of movements. “
oh this is wonderful i think this is it. It only ‘cares’ about the initial start of a sequence; it is the chooser by index basically.
It chooses chunks of sequences; groups in order; partial order sets, and you can disrupt each sequence at certain point and choose a different sequence via Pre-SMA
