NIBS-driven brain plasticity.

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Neuromodulation

Background:

• The brain exhibits plasticity, enabling functional changes and reorganization after injury or environmental shifts.
• Non-invasive brain stimulation (NIBS) techniques, specifically transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), are increasingly utilized to study brain plasticity.
• Emerging evidence suggests TMS and tDCS as potential interventions to enhance neurorehabilitation and motor function recovery post-brain lesions.

Purpose of the Study:

• To review the application of NIBS in experimental protocols for assessing and modulating brain plasticity.
• To explore factors influencing inter-individual variability in response to NIBS.
• To discuss proposed mechanisms of action and challenges in translating NIBS findings from research to clinical practice.

Main Methods:

• Literature review of studies employing NIBS (TMS, tDCS) for brain plasticity evaluation and modulation.
• Analysis of factors contributing to response variability in NIBS.
• Examination of proposed neurobiological mechanisms underlying NIBS effects.
• Assessment of translational challenges in clinical neurorehabilitation.

Main Results:

• NIBS techniques provide valuable tools for investigating and influencing brain plasticity.
• Significant inter-individual variability exists in responses to NIBS, influenced by various factors.
• Understanding the mechanisms and variability is crucial for effective clinical application.
• Translating promising research findings into widespread clinical practice faces several hurdles.

Conclusions:

• NIBS, including TMS and tDCS, offers significant potential for understanding and manipulating brain plasticity.
• Further research is needed to optimize NIBS protocols and overcome translational barriers for neurorehabilitation.
• Addressing inter-individual variability is key to maximizing the therapeutic benefits of NIBS in clinical settings.
