The goal of this short article is to summarize how random field theory has been used to test for activations in brain mapping applications. It is intended to be a general discussion and hence it is not very specific to individual applications. Tables of most widely used random fields, examples of their applications, as well as references to distributions of some of their relevant statistics are...

One of the primary objectives of human brain mapping is the division of the cortical surface into functionally distinct regions, i.e. parcellation. While it is generally agreed that at macro-scale different regions of the cortex have different functions, the exact number and configuration of these regions is not known. Methods for the discovery of these regions are thus important, particularly ...

In this paper we present a new, data-driven mapping of five ACT-R modules on the brain. In the last decade, many studies have been published that evaluated ACT-R models based on their ability to predict fMRI data in certain predefined brain regions. However, these predefined regions were based on a reading of the literature, and might not be optimal. Currently, we used the results of a model-ba...

The human brain cortex is a highly convoluted sheet of gray matter composed of folds (gyri) and fissures (sulci). Sulci serve as important macroscopic landmarks to distinguish different functional areas of the brain. The exact segmentation and identification of sulci is critical for human brain mapping studies that aim at finding correspondences between structures and their function. In this pa...
