An image-computable model of speeded decision-making

1 code implementation25 Mar 2024 Paul I. Jaffe, Gustavo X. Santiago-Reyes, Robert J. Schafer, Patrick G. Bissett, Russell A. Poldrack

Evidence accumulation models (EAMs) are the dominant framework for modeling response time (RT) data from speeded decision-making tasks.

The Brain Imaging Data Structure (BIDS) is a community-driven standard for the organization of data and metadata from a growing range of neuroscience modalities.

Self-Supervised Learning of Brain Dynamics from Broad Neuroimaging Data

1 code implementation22 Jun 2022 Armin W. Thomas, Christopher Ré, Russell A. Poldrack

At their core, these frameworks learn the dynamics of brain activity by modeling sequences of activity akin to how sequences of text are modeled in NLP.

Differentiable programming for functional connectomics

1 code implementation31 May 2022 Rastko Ciric, Armin W. Thomas, Oscar Esteban, Russell A. Poldrack

We introduce a new analytic paradigm and software toolbox that implements common operations used in functional connectomics as fully differentiable processing blocks.

DeepDefacer: Automatic Removal of Facial Features via U-Net Image Segmentation

no code implementations31 May 2022 Anish Khazane, Julien Hoachuck, Krzysztof J. Gorgolewski, Russell A. Poldrack

In this paper, we introduce DeepDefacer, an application of deep learning to MRI anonymization that uses a streamlined 3D U-Net network to mask facial regions in MRI images with a significant increase in speed over traditional de-identification software.

Comparing interpretation methods in mental state decoding analyses with deep learning models

no code implementations31 May 2022 Armin W. Thomas, Christopher Ré, Russell A. Poldrack

Deep learning (DL) models find increasing application in mental state decoding, where researchers seek to understand the mapping between mental states (e. g., perceiving fear or joy) and brain activity by identifying those brain regions (and networks) whose activity allows to accurately identify (i. e., decode) these states.

NEMAR: An open access data, tools, and compute resource operating on NeuroElectroMagnetic data

no code implementations4 Mar 2022 Arnaud Delorme, Dung Truong, Choonhan Youn, Subha Sivagnanam, Kenneth Yoshimoto, Russell A. Poldrack, Amit Majumdar, Scott Makeig

To take advantage of recent and ongoing advances in large-scale computational methods, and to preserve the scientific data created by publicly funded research projects, data archives must be created as well as standards for specifying, identifying, and annotating deposited data.

Challenges for cognitive decoding using deep learning methods

no code implementations16 Aug 2021 Armin W. Thomas, Christopher Ré, Russell A. Poldrack

In cognitive decoding, researchers aim to characterize a brain region's representations by identifying the cognitive states (e. g., accepting/rejecting a gamble) that can be identified from the region's activity.

Computational and informatics advances for reproducible data analysis in neuroimaging

no code implementations24 Sep 2018 Russell A. Poldrack, Krzysztof J. Gorgolewski, Gael Varoquaux

We argue that openness and transparency are critical for reproducibility, and we outline an ecosystem for open and transparent science that has emerged within the human neuroimaging community.

The Dynamics of Functional Brain Networks: Integrated Network States during Cognitive Function

1 code implementation10 Nov 2015 James M. Shine, Patrick G. Bissett, Peter T. Bell, Oluwasanmi Koyejo, Joshua H. Balsters, Krzysztof J. Gorgolewski, Craig A. Moodie, Russell A. Poldrack

Higher brain function relies upon the ability to flexibly integrate information across specialized communities of brain regions, however it is unclear how this mechanism manifests over time.

False discovery rate smoothing

1 code implementation22 Nov 2014 Wesley Tansey, Oluwasanmi Koyejo, Russell A. Poldrack, James G. Scott

We also apply the method to a data set from an fMRI experiment on spatial working memory, where it detects patterns that are much more biologically plausible than those detected by standard FDR-controlling methods.
