Relationship between Non-Invasive Brain Stimulation and Autonomic Nervous System

Area of Science:

• Neuroscience
• Autonomic Nervous System Research
• Brain Stimulation Techniques

Background:

• Non-invasive brain stimulation (NIBS) methods, including transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS), are gaining prominence in clinical and basic neuroscience.
• These techniques offer insights into cortical excitability and have shown potential in managing clinical disorders.
• The autonomic nervous system (ANS) is increasingly utilized as an outcome measure in NIBS research to assess overall effects and safety profiles.

Purpose of the Study:

• To review the current understanding of Non-invasive brain stimulation (NIBS) and its relationship with the autonomic nervous system (ANS).
• To highlight the contradictory findings in recent research concerning the effects of NIBS on the ANS.
• To emphasize the importance of the reciprocal relationship between central modulation and ANS function for a comprehensive understanding of NIBS.

Main Methods:

• Review of existing literature on Non-invasive brain stimulation (NIBS) techniques, specifically tDCS and rTMS.
• Analysis of studies investigating the impact of cortical modulation on autonomic functions.
• Examination of research employing the ANS as an outcome measure in NIBS studies.

Main Results:

• Non-invasive brain stimulation (NIBS) has demonstrated effects on cortical excitability and shown promise in clinical applications.
• Previous research indicates changes in muscular sympathetic nerve activity with motor cortex modulation.
• Recent studies on the connection between NIBS and the ANS have yielded contradictory findings.

Conclusions:

• Non-invasive brain stimulation (NIBS) is a valuable tool for understanding the cortical control of the ANS.
• Further research is needed to reconcile conflicting findings regarding NIBS and ANS interactions.
• Understanding the bidirectional relationship between central modulation and ANS function is crucial for advancing NIBS research.
