The article compares different methods for analyzing brain imaging data to see which one is best at finding true brain activity. They looked at three common methods: Bonferroni, Gaussian random field, and Benjamini-Hochberg. The study found that Gaussian random field was better at finding true brain activity than Bonferroni, but it was more variable with weaker brain signals. Overall, the variability in detecting true brain activity was lower with Gaussian random field compared to Bonferroni.
