Summary: The study showed that the GABA(B) agonist baclofen impairs retention of visuomotor learning but has no significant effect on motor sequence learning. Overall, baclofen did not alter GABA(B) inhibition, but changes in GABA(B) inhibition correlated with aspects of visuomotor learning retention. Further research is needed to investigate the impact of baclofen on motor rehabilitation in patients.

Summary: Learning similar motor skills in close succession is limited by interference due to unstable motor memories, which compete for neural resources. Prolonged training at the asymptote of an initial motor skill reduces interference when acquiring a second skill, with downregulation of excitatory neurotransmission in the primary motor cortex being a potential marker of online motor memory stabilization.

Summary: The study showed that when peripheral electrical stimulation was delivered 25 and 35 ms earlier to the ipsilateral cerebellum in healthy subjects, there was a significantly weaker cerebellar brain inhibition (CBI). This suggests that somatosensory inputs may modulate the inhibitory effect of the cerebellum on the primary motor cortex.

Summary: This study examined the effect of repetitive high-frequency visual stimulation on visual perceptual learning. The findings suggest that high-frequency stimulation can enhance orientation detection performance after a single task session, but can impair performance after training-based perceptual learning. These results may indicate reversal dynamics in elevated network excitation.

Summary: The study compared corticospinal excitability and motor representation assessed with transcranial magnetic stimulation (TMS) between long-term resistance trained (LRT, >= 3 years) and untrained (UNT) males. The results showed that long-term resistance trained individuals have higher neural efficiency and that TMS map size is mainly determined by TMS intensity, even when MEP responses at the hotspot are matched among individuals.

Summary: Transcranial direct current stimulation (tDCS) applied to the primary motor cortex (M1) improves motor learning in relatively simple motor tasks performed with the hand and arm, but its effect on complex motor tasks involving whole-body coordination is unclear. This study found that tDCS applied over multiple days can improve motor learning in a complex overhand throwing task.

Summary: The study found that iTBS targeted on M1 did not influence BCI accuracy or facilitate neuroplastic changes after BCI training. Other brain regions may need to be further investigated as potentially effective stimulation targets.

Summary: Dopamine plays a crucial role in neuroplasticity and has dosage-dependent effects on motor cortex plasticity. Different dosages of dopamine precursor such as L-DOPA can either impair, abolish, preserve, or reverse plasticity in healthy individuals. Similarly, selective D1-like and D2-like receptor activation has excitatory and inhibitory effects on plasticity. However, the effects of nonselective dopamine agonists like apomorphine on plasticity have not been extensively explored in humans.

Summary: Through a study involving 33 healthy subjects, it was found that unilateral motor practice leads to improved performance of both the trained and untrained contralateral limbs. The transfer of this skill is asymmetric and relates to the modulation of specific inhibitory interhemispheric connections.

Summary: Sensorimotor training and strength training can improve balance control. Little is known about how repeated balance perturbation training affects balance performance and its neural mechanisms. This study found that balance perturbation training led to less body sway and a potential increase in spinal-level involvement, indicating possible movement automaticity after perturbation training.

Summary: This study aimed to investigate the peripheral and central factors involved in the reduction of motor performance following eccentric exercise and delayed onset muscle soreness (DOMS) in both treated and contralateral limbs. The results showed that central factors played a significant role in the reduction of force immediately following eccentric exercise and during the later stage of DOMS.

Summary: Humans are able to generate target-directed visuomotor responses in less than 100 ms after stimulus onset, termed stimulus-locked responses (SLRs). Recent research suggests that the predictability of target onset time is crucial for eliciting more frequent and stronger SLRs, regardless of the kinematic attributes of the target's motion. This indicates that an internal timer, possibly located in the cerebral cortex, plays a role in priming the processing of visual input and motor output within the superior colliculus to produce SLRs.

Summary: The study found that individuals with cerebral palsy have significantly lower plantar and dorsiflexion strength compared to typically developed individuals. While the average voluntary activation capacity is also lower, a portion of individuals with CP can still achieve high levels of activation. In high functioning CP individuals, there is no strong correlation between plantar flexion voluntary activation capacity and strength or gait function.

Summary: The study aimed to determine and compare injury rates, patterns, and associated factors between elite Malaysian able-bodied and para-badminton players. Both groups showed similarities in injury patterns, with lower limb injuries being most common. For able-bodied players, injuries often occurred during training and have been increasing over the past decade. Meanwhile, para-badminton players commonly experienced overuse shoulder and knee injuries.

Summary: The study found that male adolescent elite badminton players exhibited greater strength in all indices, while female players did not show significant differences in shoulder and knee strength between age groups. For males, growth and maturation had a greater contribution to strength gains compared to training, while for females, growth, maturation, and training did not improve strength.

Summary: The present study examined errors in an isometric goal-directed aiming task during familiarization at different hand orientations. The results showed that familiarization required three sets regardless of hand orientation. Aiming errors without feedback were significantly higher than with feedback after familiarization. Hand orientation did not affect familiarization and mechanisms similar to rapid learning may be involved. Learning appeared to be consolidated during familiarization with feedforward input to maintain performance. Proprioceptive feedback reduced errors early, while online visual feedback reduced errors later, independent of hand orientation.

Summary: Intense sound can influence motor responses during muscle contraction, with different effects observed during action preparation. This study explores the impact of sustaining a muscle contraction during preparation for a ballistic action on the facilitation of motor output by a loud acoustic stimulus (LAS), known as the StartReact effect. The findings suggest that maintaining a low-force contraction in the contralateral limb enhances the facilitation by the LAS, which may have implications for stroke rehabilitation.

Summary: Through computer modeling and simulation, we explored the potential influence of accentuated eccentric loading (AEL) on enhanced power and energy storage during vertical jumping. However, our model did not show improved jump performance with AEL, and there was no additional tendon-loading effect compared to non-AEL condition.
