Neural ensemble reactivation in REM and SWS coordinate with muscle activity to promote rapid motor skill learning
<p>Neural activity patterns of recent experiences are reactivated during sleep in structures critical for memory storage, including hippocampus and neocortex. This reactivation process is thought to aid memory consolidation. Although synaptic rearrangement dynamics following learning involve an interplay between slow-wave sleep (SWS) and rapid eye movement sleep (REM), most physiological evidence implicates SWS directly following experience as a preferred window for reactivation. Here we show that reactivation occurs in both REM and SWS, and that coordination of REM and SWS activation on the same day is associated with rapid learning of a motor skill. We performed 6-hour recordings from cells in rats' motor cortex as they were trained daily on a skilled reaching task. In addition to SWS following training, reactivation occurred in REM, primarily during the pre-task rest period, and REM and SWS reactivation occurred on the same day in rats that acquired the skill rapidly. Both pre-task REM and posttask SWS activation were coordinated with muscle activity during sleep, suggesting a functional role for reactivation in skill learning. Our results provide the first demonstration that reactivation in REM sleep occurs during motor skill learning, and that coordinated reactivation in both sleep states on the same day, although at different times, is beneficial for skill learning.</p>
Cholecystokinin facilitates motor skill learning by modulating neuroplasticity in the motor cortex
<p>Cholecystokinin (CCK) is an essential modulator for neuroplasticity in sensory and emotional domains. Here, we investigated the role of CCK in motor learning using a single pellet reaching task in mice. Mice with a knockout of <em>cck</em> gene (CCK<sup>-/-</sup>) or blockade of CCK-B receptor (CCKBR) showed defective motor learning ability; the success rate of retrieving reward remained at the baseline level compared to the wildtype mice with significantly increased success rate. We observed no long-term potentiation (LTP) upon high-frequency stimulation (HFS) in the motor cortex of CCK<sup>-/-</sup> mice, indicating a possible association between motor learning deficiency and neuronal plasticity in the motor cortex. In vivo calcium imaging demonstrated that the deficiency of CCK signalling disrupted the refinement of population neuronal activity in the motor cortex during motor skill training. Anatomical tracing revealed direct projections from CCK-expressing neurons in the rhinal cortex to the motor cortex. Inactivating the CCK neurons in the rhinal cortex using chemogenetic methods significantly suppressed motor learning, and intraperitoneal application of CCK4, a tetrapeptide CCK agonist, rescued the motor learning deficits of CCK<sup>-/-</sup> mice. In summary, our results suggest that CCK, which could be provided from the rhinal cortex, enables neuroplasticity in the motor cortex leading to motor skill learning.</p>

Data from: High-speed displays encoding motor skill trigger elevated territorial aggression in downy woodpeckers
1) Many species perform social displays that incorporate complex body movements. However, the reason why such exaggerated behavioral signals evolve in the first place is unclear. 2) Recent work posits that physical displays arise in part because they showcase an animal's motor skill—that is, the ability to produce challenging motor acts with great coordination, precision, and/or speed. Support for this idea is largely correlational, with few studies attempting to manipulate metrics of motor skill to assess their effect on physical display efficacy. 3) Here, we address this issue in the downy woodpecker (Dryobates pubescens). Individuals of this species compete for territories through the performance of drums, which are complex displays produced by rapidly hammering the bill against a resonate surface at rates of 16 hits sec-1. This display is a whole-body endeavor, and its production relies on the ability to swiftly oscillate the head forward and backward at fraction-of-a-second periods. 4) Using a series of playback studies, we expose resident birds to experimentally engineered drums that reflect putative fine-scale differences in the motor command of the head and neck. We show that resident individuals respond more aggressively to drums characterized by a cadence with a 9-msec faster beat speed. These residents even modulate their own drum speed to resemble this high-performance stimulus, although they often fail to reach it. Residents also appear to appraise drum acceleration by listening to the time intervals between successive beats in a single drum, while tracking how these time intervals change as the signal progresses. 5) Our data support a connection between motor skill and the effectiveness of a physical display produced through elaborate body movement. We therefore suspect that motor skill is adaptive and evolves in response to selection by competition for effective drum displays.
Data from: How can ten fingers shape a pot? Evidence for equivalent function in culturally distinct motor skills
Behavioural variability is likely to emerge when a particular task is performed in different cultural settings, assuming that part of human motor behaviour is influenced by culture. In analysing motor behaviour it is useful to distinguish how the action is performed from the result achieved. Does cultural environment lead to specific cultural motor skills? Are there differences between cultures both in the skills themselves and in the corresponding outcomes? Here we analyse the skill of pottery wheel-throwing in French and Indian cultural environments. Our specific goal was to examine the ability of expert potters from distinct cultural settings to reproduce a common model shape (a sphere). The operational aspects of motor performance were captured through the analysis of the hand positions used by the potters during the fashioning process. In parallel, the outcomes were captured by the geometrical characteristics of the vessels produced. As expected, results revealed a cultural influence on the operational aspects of the potters' motor skill. Yet, the marked cultural differences in hand positions used did not give rise to noticeable differences in the shapes of the vessels produced. Hence, for the simple model form studied, the culturally-specific motor traditions of the French and Indian potters gave rise to an equivalent outcome, that is shape uniformity. Further work is needed to test whether such equivalence is also observed in more complex ceramic shapes.

Normative feedback on performance in a closed motor skill task: A randomized controlled study
<p><span>Augmented feedback can alter motor performance. This study examines whether, in the short term, positive normative feedback influences the execution of a closed motor task differently compared to negative normative feedback and exact augmented feedback. Using a double-blind experimental design, 68 students (73.5% female, <span><em>M<sub>age</sub></em><sub> </sub></span><span></span><span>= </span><span>21.63</span>, <span><em>SD</em> = 2.88) </span>were randomized into three groups: G1 - Exact Augmented Feedback Group (</span><span>𝑛</span><span> = 21), G2 - Positive Normative Feedback Group (</span><span>𝑛</span><span> </span><span>= 24), and G3 - Negative Normative Feedback Group (</span><span>𝑛</span><span> </span><span>= 23). The dependent variable was the score obtained in a dart-throwing task. Results showed that participants receiving positive normative feedback achieved higher scores than those receiving negative normative feedback or exact augmented feedback. These differences persisted in retention and transfer tests conducted 24 hours after the practice phase but only between the positive NF group and the exact AF group. Meanwhile, the exact augmented feedback group performed similarly to the negative normative feedback group. These findings have practical implications for training and execution in motor tasks, potentially contributing to enhanced athletic performance.</span></p>
