Advancing working memory research through cortico-cortical transcranial magnetic stimulation

Area of Science:

• Cognitive Neuroscience
• Neuroscience
• Psychology

Background:

• Working memory (WM) has been extensively studied, revealing complex neural underpinnings.
• Emerging theories, like the distributed view of WM, necessitate advanced research methodologies.
• Current methods may not fully capture the nuanced neural dynamics proposed by newer WM models.

Purpose of the Study:

• To explore how advanced transcranial magnetic stimulation (TMS) techniques can be applied to study working memory.
• To discuss the potential of cortico-cortical TMS in testing predictions of the distributed view of working memory.
• To identify barriers and provide examples for implementing cortico-cortical TMS in WM research.

Main Methods:

• Review of state-of-the-art transcranial magnetic stimulation (TMS) techniques.
• Conceptual framework for applying cortico-cortical TMS to working memory research.
• Discussion of challenges and potential solutions for implementing novel TMS protocols.

Main Results:

• Cortico-cortical TMS offers a promising avenue for investigating the distributed nature of working memory.
• The application of TMS can be guided by ongoing debates, such as the sensory recruitment framework.
• Specific examples illustrate how cortico-cortical TMS can probe WM functions.

Conclusions:

• Advanced TMS methods, particularly cortico-cortical TMS, are crucial for the progression of working memory research.
• Overcoming implementation barriers will unlock new possibilities for understanding WM's neural basis.
• This approach holds potential for refining and validating contemporary theories of working memory.
