On Clustering fMRI Time Series

  title={On Clustering fMRI Time Series},
  author={Cyril Goutte and Peter Aundal Toft and Egill Rostrup and Finn {\AA}rup Nielsen and Lars Kai Hansen},
Analysis of fMRI time series is often performed by extracting one or more parameters for the individual voxels. Methods based, e.g., on various statistical tests are then used to yield parameters corresponding to probability of activation or activation strength. However, these methods do not indicate whether sets of voxels are activated in a similar way or in different ways. Typically, delays between two activated signals are not identified. In this article, we use clustering methods to detect…

Spatiotemporal clustering of fMRI time series in the spectral domain

Feature‐space clustering for fMRI meta‐analysis

It is shown that the feature space clustering approach yields nontrivial results and, in particular, shows interesting differences between individual voxel analysis performed with traditional methods.

Feature Space Clustering for Fmri Meta-analysis Feature-space Clustering

This contribution investigates the applicability of a clustering method applied to features extracted from the fMRI data, and shows that the feature space clustering approach yields non-trivial results, and in particular shows interesting di erences between individual voxel analysis performed with traditional methods.

Detection of Spatial Activation Patterns as Unsupervised Segmentation of fMRI Data

This work proposes to simultaneously estimate the optimal representative time courses that summarize the fMRI data well and the partition of the volume into a set of disjoint regions that are best explained by these Representative time courses.

Neural networks approach to clustering of activity in fMRI data

Exploiting the intracluster correlations, it is shown that regions of substantial correlation with an external stimulus can be unambiguously separated from other activity.

Discovering Structure in the Space of Activation Profiles in fMRI

A mixture model is designed that finds the major activation patterns along with their localization maps and derive an algorithm for fitting the model to the fMRI data, which enables functional group analysis independent of spatial correspondence among subjects.

Visualizing Brain Activity from fMRI Data

This paper proposes a methodology to visualize brain function in a time-varying fashion that will allow neurologists to not only validate the static activation maps, but also to develop a better understanding of temporal characteristics of the activation patterns.

Spatial patterns and functional profiles for discovering structure in fMRI data

In both applications, unsupervised, hypothesis-free methods for fMRI analysis in two different types of experiments confirm previously known results in brain mapping and point to new research directions for exploratory analysis of fMRI data.

Brain Activity Detection - Statistical Analysis of fMRI Data

A spatiotemporal model for detecting brain activity in fMRI is proposed that improves the inference ability since it takes into account the uncertainty in both the spatial and the temporal dimension.



Analysis of fMRI Time-Series Revisited—Again

Correct results are presented that replace those of the previous paper and solve the same problem without recourse to heuristic arguments and a proper and unbiased estimator for the error terms are introduced.

Non‐linear Fourier Time Series Analysis for Human Brain Mapping by Functional Magnetic Resonance Imaging

A non-linear parametric model for brain activation detection by functional magnetic resonance imaging (FMRI) is proposed that generalizes an existing method for human brain mapping.

Fuzzy clustering of gradient‐echo functional MRI in the human visual cortex. Part I: Reproducibility

Fuzzy clustering is a robust, model‐independent method to extract functional information in time and space and intertrial reproducibility of cortical activation is significantly improved by the capability of fuzzy clustering.

Assessment and optimization of functional MRI analyses

This report compared several commonly‐used data analysis strategies for conventional fMRI data by evaluating statistical testing, spatial filtering, and thresholding, and found that the independent t‐test and crosscorrelation coefficient were the most powerful statistical tests, performing identically well.

Fuzzy clustering of gradient‐echo functional MRI in the human visual cortex. Part II: Quantification

Fuzzy clustering of fMRI data is a robust and efficient method to separate functional brain activation from noise or other sources resulting in time‐dependent signal changes as proven by simulated f MRI data analysis and in vivo data from the visual cortex.

Pattern Recognition and Neural Networks

Professor Ripley brings together two crucial ideas in pattern recognition; statistical methods and machine learning via neural networks in this self-contained account.

First International Conference on Functional Mapping of the Human Brain

The following topics were selected: new perspectives in experimental stroke research; molecular rationale for new therapeu­ tical strategies; and genetic modelling for brain diseases and imaging of human pathophys­ iology.

Robust clustering methods: a unified view

This paper analyzes several popular robust clustering methods and concludes that they have much in common, establishing a connection between fuzzy set theory and robust statistics, and pointing out the similarities between robust clusters methods and statistical methods.
