📘 New Publication: Cognitive Modes Detectable with Task-Based fMRI
Functional magnetic resonance imaging (fMRI) is a widely used neuroimaging method for mapping brain activity with high spatial resolution. Over the past 30 years, it has transformed both cognitive and clinical neuroscience by helping identify active brain regions during tasks and rest, supporting research and guiding treatment development.
Cognitive Modes Detectable with Task-Based fMRI introduces a new framework for interpreting fMRI data: linking spatial BOLD patterns to specific cognitive functions. By emphasizing replicability and reducing reverse inference errors, this approach aims to provide a clearer one-to-one mapping between brain networks and cognition.
Atlas of Task-Based Brain Networks
These brain image templates were created by averaging over exemplars of each network. Published versions that contributed to the exemplars are listed in the PDF file stored with the templates.

fMRI-CPCA Software
The software (MATLAB graphical user interface) and manual for the multivariate analysis of fMRI data can be downloaded from this site. For an example of how the CPCA software works, please click here. For a brief description of CPCA methodology, click here.
BADE Task
(For a more detailed introduction, please refer to the two papers below).
In the BADE task, participants rate the plausibility of four interpretations of a scenario as new evidence is revealed, measuring flexibility in belief updating. This task has been reliably found to correlate with the severity of delusions in schizophrenia.
Instructions:
Download the compressed folder in the link below (BADE Task Files) and unpack the files. The package includes one executable file, two configuration files, an instruction guide, and two peer reviewed articles. The instructions for how to initiate and run the task are outlined in the guide.
This version of the BADE task is revised to include a wider variety of lures.
