Thresholding of Statistical Maps in Functional Neuroimaging Using the False Discovery Rate
This paper introduces to the neuroscience literature statistical procedures for controlling the false discovery rate (FDR) and demonstrates this approach using both simulations and functional magnetic resonance imaging data from two simple experiments.

Threshold-free cluster enhancement: Addressing problems of smoothing, threshold dependence and localisation in cluster inference
Nonparametric permutation tests for functional neuroimaging: A primer with examples
The standard nonparametric randomization and permutation testing ideas are developed at an accessible level, using practical examples from functional neuroimaging, and the extensions for multiple comparisons described.

An automated brain-mapping framework that uses text-mining, meta-analysis and machine-learning techniques to generate a large database of mappings between neural and cognitive states is described and validated.

It is found that the most common software packages for fMRI analysis (SPM, FSL, AFNI) can result in false-positive rates of up to 70%.

Controlling the familywise error rate in functional neuroimaging: a comparative review
It is found that Bonferroni-related tests offer little improvement over Bonferronsi, while the permutation method offers substantial improvement over the random field method for low smoothness and low degrees of freedom.
