Summary: This study investigated the effectiveness of three different bilateral tDCS protocols on bimanual hand-grip force control capabilities in healthy young adults. The results showed that bilateral anodal stimulation significantly improved bilateral motor synergies, suggesting that promoting motor cortical activations between hemispheres is an additional option for enhancing interlimb coordination patterns.

Summary: This study compared the effects of anodal transcranial direct current stimulation (tDCS) on the cerebellum and cerebral motor cortex in stroke patients. The results showed that tDCS improved gait, balance, and the risk of falls in stroke patients, but did not significantly improve cognitive function.

Summary: This study found that stimulation of the right or left prefrontal cortex during motor learning in older adults actually slowed down the learning process, contrary to the researchers' predictions. The right prefrontal cortex was found to play an important role in early sequence learning, while the left prefrontal cortex was involved in chunking in older adults.

Summary: This study investigated the cortical responses and mechanism underlying changes in ankle force control task induced by transcranial direct current stimulation (tDCS). Results showed that the task decreased alpha and beta power spectral densities (PSDs) in the sensorimotor cortex, and tDCS decreased the task performance and beta PSD. There was a significant association between the changes in task performance and beta PSD. In conclusion, ankle force control task activated a distributed cortical network and tDCS enhanced ankle force control and modulated beta-band activity in the sensorimotor cortex.

Summary: Repeated anodal transcranial direct current stimulation (atDCS) in rats was found to hasten the appearance of emergence behavioral marker and decrease the time to acknowledgment of adhesive tape during recovery from isoflurane anesthesia, indicating a faster recovery process. Additionally, atDCS-treated rats spent more time exploring novel objects and environments, suggesting a potential enhancement of visual and working memory functions by atDCS.

Summary: This study manipulated task types and predictability to investigate the role of the DLPFC in task-switching performances, finding that anodal tDCS may have a stronger influence over the right DLPFC by changing the irrelevant task-set inhibition process. The right DLPFC is unlikely to act by performing exogenous adjustment of predictable task switching.

Summary: This study investigated the effect of transcranial direct current stimulation (tDCS) on visual perceptual learning (VPL) and found that applying anodal tDCS during daily training enhanced performance improvement. However, applying anodal tDCS before training did not improve VPL. There was no difference in within-session and between-session improvement among the online, offline, and sham tDCS conditions.

Summary: The study found that administering anodal stimulation at the primary motor cortex (M1) during repetitive practice can improve retention performance, with interleaved practice showing better results compared to repetitive practice. M1 plays a crucial role in the early consolidation of novel motor skills, especially in facilitating offline gains.

Summary: This study compared the effects of conventional and high-definition transcranial direct current stimulation on corticospinal excitability, cortico-cortical excitability and intra-individual variability under conventional and HD electrode montages. The results indicated that the two electrode montages had little effect on corticospinal excitability, but there was a significant difference in HD c-tDCS at 0 minutes post-stimulation. Conventional tDCS was more effective at reducing intra-individual variability compared to HD-tDCS.
