Motor training consisting of repetitive thumb movements results in encoding of motor memories in the primary motor cortex. It is not known if proprioceptive input originating in the training movements is sufficient to produce this effect. In this study, we compared the ability of training consisting of voluntary (active) and passively-elicited (passive) movements to induce this form of plasticity. Active training led to successful encoding accompanied by characteristic changes in corticomotor excitability, while passive training did not. These results support a pivotal role for voluntary motor drive in coding motor memories in the primary motor cortex.

Motor memories become resistant to interference by the process of consolidation, which leads to long-term retention. Studies have shown involvement of the somatosensory cortex in motor learning-related plasticity, but not directly in motor memory consolidation. This Neuro Forum article reviews evidence from a continuous theta-burst transcranial magnetic stimulation (cTBS) study by Kumar and colleagues (Kumar N, Manning TF, Ostry DJ. PLoS Biol 17: e3000469, 2019) that demonstrates the role of somatosensory, rather than motor, cortex in human motor memory consolidation during implicit motor learning.

Vestibulo Ocular Reflex

Cerebellar climbing fiber activity encodes performance errors during many motor learning tasks, but the role of these error signals in learning has been controversial. We compared two motor learning paradigms that elicited equally robust putative error signals in the same climbing fibers: learned increases and decreases in the gain of the vestibulo-ocular reflex (VOR). During VOR-increase training, climbing fiber activity on one trial predicted changes in cerebellar output on the next trial, and optogenetic activation of climbing fibers to mimic their encoding of performance errors was sufficient to implant a motor memory. In contrast, during VOR-decrease training, there was no trial-by-trial correlation between climbing fiber activity and changes in cerebellar output, and climbing fiber activation did not induce VOR-decrease learning. Our data suggest that the ability of climbing fibers to induce plasticity can be dynamically gated in vivo, even under conditions where climbing fibers are robustly activated by performance errors.

Kinesthetic Information

Two experiments were conducted to examine the role of overt rehearsal of kinesthetic information on recall. In Exp. 1 preselected criterion movements were recalled with greater precision than constrained criterion movements but the benefits of overt rehearsal were negligible. In Exp. 2, 5 overt rehearsals improved replication of preselected movements (compared to 0 or 3) but rehearsal did not differ from immediate recall.

Inspection Task

A method of investigating mental imagery is presented which shows that movements and imagery of movements are functionally equivalent. Experiment I uses a short-term-motor-memory linear positioning task in which a novel movement interpolated between initial presentation and recall of a criterion movement length can bias recall. It was predicted that if a similar bias occurred when the interpolated novel movement was imagined rather than performed, then imagery of movements had effects on memory which were functionally similar to producing movements. The results showed that imagery for movements did produce a similar bias. In Experiment II a second order interference task was introduced while instructions to imagine movements were carried out. It was predicted that if imagery for movements were based on the visual/perceptual system then a simultaneous visual inspection task should inhibit imagery. If imagery were based on the motor system though, a simultaneous motor task should prohibit imagery. The results showed that a visual task inhibited imagery. The role of visual imagery in movement control is discussed in terms of spatial representations.
