This study introduces practical guidelines for using Bayesian inference in SPM 12 for functional Magnetic Resonance Imaging (fMRI) data analysis. It compares Bayesian and classical methods, offering insights for researchers navigating beyond the traditional P < 0.05 threshold.

Area of Science:

  • Neuroscience
  • Psychology
  • Statistics
  • Data Analysis

Background:

  • The conventional P < 0.05 threshold for analyzing functional Magnetic Resonance Imaging (fMRI) data is under debate in neuroscience and psychology.
  • Bayesian inference is emerging as a potential alternative methodology for fMRI data analysis.
  • There is a lack of practical guidance for end-users of fMRI analysis tools, like SPM 12, on implementing Bayesian inference.

Purpose of the Study:

  • To demonstrate the utilization of Bayesian second-level inference within the SPM 12 software.
  • To provide practical guidelines for setting parameters and interpreting results of Bayesian inference in SPM 12.
  • To compare Bayesian second-level inference outcomes with classical second-level inference to aid user understanding.

Main Methods:

  • Utilized publicly available fMRI data from NeuroVault for analysis.
  • Implemented Bayesian second-level inference in SPM 12.
  • Compared results from Bayesian second-level inference with those from classical second-level inference.

Main Results:

  • Successfully demonstrated the application of Bayesian second-level inference in SPM 12.
  • Provided practical parameter settings and interpretation guidelines for Bayesian inference, including Bayes factors.
  • Highlighted the differences and similarities between Bayesian and classical second-level inference outcomes.

Conclusions:

  • Bayesian inference offers a viable and practical alternative for fMRI data analysis in SPM 12.
  • The study provides essential guidance for researchers transitioning to Bayesian methods.
  • Further exploration of Bayesian inference benefits and future research directions in neuroimaging are warranted.
