Controlling the familywise error rate in functional neuroimaging: a comparative review
T Nichols, S Hayasaka - Statistical methods in medical …, 2003 - journals.sagepub.com
… We evaluate these approaches on t images using simulations and a collection of real
datasets. We find that Bonferroni-related tests offer little improvement over Bonferroni, while the …

Scanning the horizon: towards transparent and reproducible neuroimaging research
Functional neuroimaging techniques have transformed our ability to probe the neurobiological
basis of behaviour and are increasingly being applied by the wider neuroscience …

[HTML][HTML] Functional connectomics from resting-state fMRI
Spontaneous fluctuations in activity in different parts of the brain can be used to study functional
brain networks. We review the use of resting-state functional MRI (rfMRI) for the purpose …

[BOOK][B] Statistical parametric mapping: the analysis of functional brain images
In an age where the amount of data collected from brain imaging is increasing constantly, it
is of critical importance to analyse those data within an accepted framework to ensure proper …

Tract-based spatial statistics: voxelwise analysis of multi-subject diffusion data
There has been much recent interest in using magnetic resonance diffusion imaging to
provide information about anatomical connectivity in the brain, by measuring the anisotropic …

Large-scale automated synthesis of human functional neuroimaging data
… We write the term indicator for study i as T i = (T ik ), a length-n T binary vector marking

Threshold-free cluster enhancement: addressing problems of smoothing, threshold dependence and localisation in cluster inference
SM Smith, TE Nichols - Neuroimage, 2009 - Elsevier
… 9, we show the TFCE-enhanced t-statistic images and the thresholded significance maps
for a range of E and H values. Where E is large, or greater than H, the enhanced maps are …

Thresholding of statistical maps in functional neuroimaging using the false discovery rate
CR Genovese, NA Lazar, T Nichols - Neuroimage, 2002 - Elsevier
… For example, a t threshold of 6 and a P value of less than 0.001 are commonly used,
though … A modified 2-T Siemens scanner was used to collect T*2-weighted EPI images. The …

Nonparametric permutation tests for functional neuroimaging: a primer with examples
TE Nichols, AP Holmes - Human brain mapping, 2002 - Wiley Online Library
