Summary
Near-infrared spectroscopy (NIRS) offers unique advantages for studying prefrontal cortex (PFC) roles in emotion processing. This review addresses NIRS challenges and strategies for its application in emotion research.
Area of Science:
- Neuroscience
- Cognitive Science
- Psychophysiology
Background:
- Near-infrared spectroscopy (NIRS) is a non-invasive neuroimaging technique.
- NIRS offers methodological advantages over other neural activation measurement tools.
- The prefrontal cortex (PFC) plays a crucial role in emotion processing.
Purpose of the Study:
- To review studies using NIRS to investigate PFC activation in emotion processing.
- To identify and address methodological challenges in applying NIRS to emotion research.
- To highlight the potential of NIRS in two key areas: biological predisposition and emotion-action interactions.
Main Methods:
- Literature review of studies employing NIRS for emotion research.
- Analysis of methodological challenges specific to NIRS in emotion studies.
- Discussion of strategies to overcome NIRS limitations.
Main Results:
- NIRS has potential for studying PFC involvement in emotion.
- Methodological challenges exist but can be mitigated.
- NIRS can advance research on biological influences on emotional responses and emotion-action interactions.
Conclusions:
- NIRS is a valuable tool for emotion research, particularly for the PFC.
- Addressing NIRS methodological challenges will enhance its utility.
- NIRS can significantly contribute to understanding emotion's biological underpinnings and its interaction with action.
