Summary: This study investigated the impact of transcranial direct current stimulation (tDCS) on explicit motor sequence learning. The findings suggest that tDCS applied to the left premotor cortex may affect the acquisition and reproduction of explicitly learned motor sequences, providing a potential target for the application of non-invasive brain stimulation techniques.

Summary: Motor memory is preserved in Parkinson's patients and may be supported by compensatory non dopamine-sensitive mechanisms. Initial learning dopamine state does not influence motor memory. Parkinson's disease and aging may affect motor memory in similar ways.

Summary: According to the study, stress induced a larger recruitment of sensorimotor regions and a greater disengagement of hippocampo-cortical networks during training, which was beneficial for initial performance but detrimental for consolidation.

Summary: Research on aging marmosets has shown that aged animals exhibit delayed onset of learning, slowed learning rate after onset, and decreased asymptotic working memory performance, which are not accounted for by age-related impairments in motor speed and motivation.

Summary: Increasing evidence supports the importance of reactivating memory traces during postlearning wakefulness for memory consolidation. This study utilized somatosensory targeted memory reactivation (TMR) to enhance the reactivation of a motor memory trace during quiet rest immediately after learning. The results showed that the reactivated motor sequence had a faster learning rate compared to the not-reactivated sequence, and brain imaging data revealed specific reactivation of motor, parietal, frontal, and cerebellar brain regions during TMR. Importantly, the TMR-induced behavioral advantage was accompanied by changes in hippocampal activity and hippocampo-motor connectivity during task practice.

Summary: Our study found that both high-intensity interval training (HIIT) and aerobic endurance exercise (AE) were effective in improving sleep-dependent procedural memory consolidation in individuals with schizophrenia. HIIT showed a more distinctive effect compared to the control group.

Summary: Investigating motor learning in patients with multiple sclerosis (MS) disease revealed that while MS patients exhibit similar learning performance as healthy controls, the long-term consolidation of sequential motor memories is impaired in MS disease. Despite slower overall reaction times, motor performance evolves similarly in all groups, with sequence learning being similar between MS patients and control groups.

Summary: Many daily movements involve multiple limbs and require the motor system to control different body parts in quick succession. Previous research on motor adaptation has focused on single limb movements or simultaneous movements of multiple limbs, but it is unclear whether multilimb sequences can support motor adaptation in a similar way. In this study, we found that only active participation in a bimanual sequential task supports pronounced adaptation, suggesting that active segments in bimanual motion sequences are linked across limbs. Additionally, prior perceptual feedback of the opposite arm contributes to force field-specific motor adaptation.

Summary: Tourette syndrome is a childhood-onset neurodevelopmental disorder characterized by motor and vocal tics. This study investigated the acquisition and retention of procedural memory in children with TS, finding evidence for short-term and long-term retention of probability-based information, but potential impairment in learning of serial-order information.

Summary: Understanding how the brain learns throughout a lifetime remains a long-standing challenge. This study explores a method of rapidly learning new information by interleaving new and old knowledge, and demonstrates its feasibility in artificial neural networks. Additionally, a theoretical model of implementing this learning approach in the brain is proposed.

Summary: This study discusses three ways in which information becomes automatically prioritized in working memory: physical salience, statistical learning, and reward learning. It integrates findings from perception and working memory studies to propose a more sophisticated understanding of the relationship between attention and working memory.

Summary: The study found that sleep-dependent memory consolidation is impaired in older adults, especially in prospective memory. While sleep benefited the performance of young adults in related intentions, it did not have a positive effect on older adults. Sleep also did not improve prospective memory for unrelated intentions in both age groups.

Summary: Accurate motor timing requires precise coupling between sensory input and motor output, and the adjustment of movements in response to changes in the environment. This study investigates the role of the primary motor cortex (M1) in error correction in the temporal domain. The results suggest that M1 is involved in the correction of nonconscious errors, particularly negative step-changes in temporal intervals.

Summary: This study investigated whether age affects sensorimotor timing and error correction in the supra-second range. The results showed that older individuals had greater variability in synchronization, lower synchronization accuracy, and reduced error correction. These findings support the use of supra-second measures for early detection of age-related changes in the motor system.

Summary: Precise motor timing requires the ability to adapt one's own movements to changes in the environment. Previous studies have shown that correcting perceived timing errors involves different brain networks compared to correcting non-perceived errors. This study aimed to clarify the role of the left ventrolateral prefrontal cortex (vPFC) in error correction using high-definition transcranial direct current stimulation (HD-tDCS). The results suggest that cathodal HD-tDCS has a negative effect specifically on the correction of perceived timing errors, supporting the importance of the left vPFC in error correction in the temporal domain.
