“…In work with prisms, it was shown that initial changes in sensed limb position initially decreased and then recover and are present up to seven days later [39]. The other notable features are that subjects that show greater motor adaptation likewise show greater perceptual change [24] and similarly, larger experimental perturbations result in larger perceptual changes [40]. …”

Summary There is accumulating evidence from behavioural, neurophysiological and neuroimaging studies that the acquisition of motor skills involves both perceptual and motor learning. Perceptual learning alters movements, motor learning and motor networks of the brain. Motor learning changes perceptual function and the brain’s sensory circuits. Here we review studies of both human limb movement and speech which indicate that plasticity in sensory and motor systems is reciprocally linked. Taken together, this points to an approach to motor learning in which perceptual learning and sensory plasticity play a fundamental role.

“…When tested the following day, subjects showed perfect retention (99.6% retained) of this shift in felt hand position. However, given the smaller magnitude following adaptation compared to our previous papers (~6° change with a 30° distortion) (Cressman and Henriques 2009;Cressman and Henriques 2010b;Cressman et al 2010;Salomonczyk et al 2011), we investigated further and noticed a group of subjects who did not show a shift in the expected direction following training with a visuomotor discrepancy (Fig. 4d, grey circles), despite having equivalent slopes (or uncertainty ranges) as the others, confirming correct performance of the task.…”

“…In our labs previous work, changes in subjects' felt hand position were not significantly related to changes in their aftereffects after free-reach training with a misaligned cursor (Cressman and Henriques 2009;Cressman and Henriques 2010b;Salomonczyk et al 2011;Salomonczyk et al 2012). However, the aforementioned relationship had not yet been investigated following an extended lapse of time.…”

“…For instance, in our previous studies that had weaved reach training trials throughout proprioceptive estimates, approximately 83 to 100% of subjects showed the expected shift in sense of hand position (Cressman and Henriques 2009;Cressman and Henriques 2010b;Cressman et al 2010;Salomonczyk et al 2011;Salomonczyk et al 2012;Clayton et al 2013), whereas in those that had not (Salomonczyk et al 2013;Mostafa et al 2014), only 72 to 91% of subjects showed this recalibration.…”

“…Salomonczyk et al (2011) had subjects train to reach with a cursor that had been rotated by 30°, 50°, and 70°. Although reaches and estimates of felt hand position were directly related to magnitude, they showed the same percent change found in previous work: 20% of the distortion for proprioceptive recalibration and 50% for motor adaptation.…”

This thesis builds on our laboratory's recent findings that visuomotor adaptation following reaches with a misaligned cursor not only induces changes in an individual's motor output, but their proprioceptive sense of hand position as well. Long-term changes are seen in motor adaptation, however very little is known about the retention of changes in felt hand position. We sought to evaluate whether this recalibration in proprioception, following visuomotor adaptation, is sufficiently robust to be retained the following day (~24 hours later), and if so, to determine its extent. Visuomotor adaptation was induced by having subjects perform reaches to visual targets using a cursor representing their unseen hand, which had been gradually rotated 45º counterclockwise. Motor adaptation and proprioceptive recalibration were determined by assessing subjects' reach aftereffects and changes in hand bias, respectively. We found that subjects adapted their reaches and recalibrated their sense of hand position following training with a misaligned cursor, as shown in Cressman and Henriques (2009). More importantly, subjects who showed proprioceptive recalibration in the direction of motor adaptation on Day 1 did retain changes in felt hand position and motor adaptation on Day 2. These findings suggest that in addition to motor changes, individuals are capable of retaining sensory changes in proprioception up to 24 hours later.iii

Proprioceptive recalibration in the right and left hands following abrupt visuomotor adaptation

Previous studies have demonstrated that after reaching with misaligned visual feedback of the hand, one adapts his or her reaches and partially recalibrates proprioception, such that sense of felt hand position is shifted to match the seen hand position. However, to date, this has only been demonstrated in the right (dominant) hand following reach training with a visuomotor distortion in which the rotated cursor distortion was introduced gradually. As reach adaptation has been shown to differ depending on how the distortion is introduced (gradual vs. abrupt), we sought to examine proprioceptive recalibration following reach training with a cursor that was abruptly rotated 30° clockwise relative to hand motion. Furthermore, because the left and right arms have demonstrated selective advantages when matching visual and proprioceptive targets, respectively, we assessed proprioceptive recalibration in right-handed subjects following training with either the right or the left hand. On average, we observed shifts in felt hand position of approximately 7.6° following training with misaligned visual feedback of the hand, which is consistent with our previous findings in which the distortion was introduced gradually. Moreover, no difference was observed in proprioceptive recalibration across the left and right hands. These findings suggest that proprioceptive recalibration is a robust process that arises symmetrically in the two hands following visuomotor adaptation regardless of the initial magnitude of the error signal.
