Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Neuromodulation

Background:

• Non-invasive brain stimulation is increasingly used to understand brain-behavior relationships and improve neuro-rehabilitation.
• Transcranial direct current stimulation (tDCS) is a cost-effective, user-friendly, and portable technique that enhances corticospinal excitability with minimal side effects.

Purpose of the Study:

• To provide an overview of tDCS as a neuromodulatory technique.
• To explore the interaction between tDCS and motor learning.
• To discuss the application of tDCS in stroke rehabilitation.

Main Methods:

• Review of existing literature on tDCS and motor learning.
• Analysis of tDCS's role in identifying functional relevance of brain regions.
• Examination of tDCS's application in facilitating motor skill acquisition.

Main Results:

• tDCS demonstrates beneficial neural effects leading to improved motor behavior.
• The technique is effective in identifying the role of specific brain regions in motor skill learning.
• tDCS can facilitate activity in cortical areas crucial for motor learning, thereby enhancing motor function.

Conclusions:

• Understanding the tDCS-motor learning interaction has significant implications for developing novel rehabilitation strategies.
• tDCS is a valuable tool for motor learning research and has potential applications in stroke recovery.
