Motor Control and Adaptation

Distributed neural dynamics underlie the shift from movement preparation to execution

Magnetoencephalography during memory-guided finger sequences shows preparation and execution occupy distinct, partly overlapping subspaces; execution patterns appear first in hippocampus and last in M1, 160 ms before the first press.

Learning source weights for target-position estimation: comparing fixed weights and an input-dependent rule

In simulation, under reduced accuracy or temporally correlated errors, recalibration or fixed-weight learning captured most gains; a disagreement-dependent rule beat fixed weights mainly under occasional large errors (4.05% lower MSE).

Consolidation alters motor sequence-specific distributed representations

In human fMRI, consolidated finger sequences are more discriminable than new ones in sensorimotor putamen, premotor and prefrontal cortices, but less so in hippocampus and caudate.
