Region of interest analysis using an SPM toolbox
TLDR
A toolbox called MarsBar is implemented for region of interest analysis within the SPM99 software package, which may have many advantages in terms of statistical power and the ease of interpretation of neuroimaging data.
Analysis of fMRI Time-Series Revisited
TLDR
The approach is predicated on an extension of the general linear model that allows for correlations between error terms due to physiological noise or correlations that ensue after temporal smoothing, and uses the effective degrees of freedom associated with the error term.

Detecting Activations in PET and fMRI: Levels of Inference and Power
TLDR
It is envisaged that set-level inferences will find a role in making statistical inferences about distributed activations, particularly in fMRI.

Combining Spatial Extent and Peak Intensity to Test for Activations in Functional Imaging
TLDR
This paper combines two tests used to assess the regional significance in functional images into a single test that is more sensitive to a wider range of signals, based on an analytical approximation of the distribution of these two parameters (size and height).

Cerebral mechanisms of word masking and unconscious repetition priming
TLDR
Within the areas associated with conscious reading, masked words activated left extrastriate, fusiform and precentral areas and reduced the amount of activation evoked by a subsequent conscious presentation of the same word.

Partially overlapping neural networks for real and imagined hand movements.
TLDR
Results suggest that a specific neuronal substrate is involved in the processing of hand motor representations in the form of cortico-subcortical areas.

Letter Binding and Invariant Recognition of Masked Words
TLDR
The results indicate that an invariant binding of letters into words is achieved unconsciously through a series of increasingly invariant stages in the left occipito-temporal pathway.

The neural system that bridges reward and cognition in humans: An fMRI study
TLDR
The study showed specific brain activation in relation with changes in both the cognitive loading and the reward associated with task performance, suggesting a balance between increasing activity in cortical cognitive areas and decreasing activity in the limbic and paralimbic structures during ongoing higher cognitive processing.

To Smooth or Not to Smooth? Bias and Efficiency in fMRI Time-Series Analysis
TLDR
It is shown that: (i) Whitening strategies can result in profound bias and are therefore probably precluded in parametric fMRI data analyses and (ii) Band-pass filtering, and implicitly smoothing, has an important role in protecting against inferential bias.

Characterizing the Response of PET and fMRI Data Using Multivariate Linear Models
TLDR
A Canonical Variates Analysis of the estimated effects of the predictors from a multivariate linear model (MLM) so that temporal correlations can be incorporated into the model, making the MLM method suitable for fMRI as well as PET data.
