Neurofeedback with fMRI: A critical systematic review

Area of Science:

• Neuroscience
• Cognitive Science
• Psychology

Background:

• Functional magnetic resonance imaging neurofeedback (fMRI-nf) offers novel methods for individuals to self-regulate brain activity and behavior.
• Existing literature on fMRI-nf is synthesized to provide a comprehensive overview and a systematic database of findings.

Purpose of the Study:

• To review the current fMRI-nf literature and establish a database of findings from 99 experiments.
• To assess the viability of self-regulating specific brain signatures and the reproducibility of behavioral outcomes.
• To identify the need for rigorous methodologies, including double-blind placebo-controlled studies, to validate fMRI-nf's specific effects.

Main Methods:

• Systematic review and synthesis of 99 fMRI-nf experiments.
• Analysis of findings related to self-regulation of brain signatures and behavioral outcomes.
• Identification of methodological requirements for future research.

Main Results:

• The majority of fMRI-nf studies indicate that self-regulation of specific brain activity patterns is achievable.
• Replication of associated behavioral improvements remains limited across studies.
• The need for double-blind placebo-controlled designs and standardized statistical analyses is emphasized to isolate neurofeedback effects.

Conclusions:

• While fMRI-nf can modulate brain activity, its translation into meaningful clinical behavioral improvements is not yet established.
• Further research is required to confirm the sustainability, transferability, and feasibility of fMRI-nf in both healthy and patient populations.
• Reducing complex mental health conditions to localized brain region modulation via fMRI-nf may be an oversimplified approach.
