From b486d41d2f43ff2c552d5e90b852bee17f94101d Mon Sep 17 00:00:00 2001 From: Alexander Terry Date: Mon, 29 Jul 2024 15:50:37 -0400 Subject: [PATCH 1/2] Added fMRI data set analysis subclasses Added fMRI data set analysis subclasses: - beta series correlation, multi-voxel pattern analysis, ROI analysis, fconn. Added fconn subclasses: - seed-based conn, resting state fconn, task-based fconn, dynamic fconn, static fconn, effective conn. Added seed-based conn subclasses: - seed voxel correlation: between-subjects, seed voxel correlation: within-subjects. Added task-based fconn subclasses: - psychophysiological interaction approach. Added new defs, and assigned ID's within the range (e.g. MRIO_1000000) for each term. --- src/ontology/MRIO-edit.owl | 156 +++++++++++++++++++++++++++++++++++++ 1 file changed, 156 insertions(+) diff --git a/src/ontology/MRIO-edit.owl b/src/ontology/MRIO-edit.owl index aa0bee6..a106543 100644 --- a/src/ontology/MRIO-edit.owl +++ b/src/ontology/MRIO-edit.owl @@ -4970,6 +4970,162 @@ The values often belong to a group of pixels or voxels that share the same chara + + + + + A method used in functional MRI data set analysis that examines correlations in activity between spatially remote brain regions. + + 2024-07-29T18:05:31Z + functional connectivity + + + + + + + + + A type of functional connectivity that reflects the direct influence of one brain region on another in relation to functional activity. + + 2024-07-29T18:08:06Z + effective connectivity + + + + + + + + + A type of functional connectivity that measures consistent or stable correlations in brain activity between regions over a period of time during functional MRI. + + 2024-07-29T18:09:46Z + static functional connectivity + + + + + + + + + A type of functional connectivity that measures temporal variations in connectivity patterns between brain regions over time during functional MRI. + + 2024-07-29T18:11:26Z + dynamic functional connectivity + + + + + + + + + A type of functional connectivity that measures the functional connectivity between brain regions while subjects perform a specific task(s) during functional MRI. + + 2024-07-29T18:16:41Z + task-based functional connectivity + + + + + + + + + A type of functional connectivity that measures the functional connectivity between brain regions while the subject is at rest during functional MRI. + + 2024-07-29T18:17:09Z + resting state functional connectivity + + + + + + + + + A method used to investigate functional connectivity between brain regions using a predefined seed voxel or region. + + 2024-07-29T18:22:19Z + seed-based connectivity + + + + + + + + + A method within functional MRI data set analysis that involves defining specific brain regions or areas of interest a priori and examining the neural activity within those regions. + + 2024-07-29T18:27:21Z + region of interest analysis + + + + + + + + + A type of functional MRI data set analysis that attempts to analyze the information present in patterns of activity rather than the response at individual voxels. + + 2024-07-29T18:27:45Z + multi-voxel pattern analysis + + + + + + + + + A method used in seed-based connectivity that involves extracting the time course from a seed voxel, determined based on some a priori hypothesis, and computing its correlation with all the voxels across the brain. + + 2024-07-29T18:31:33Z + seed voxel correlation: within-subjects + + + + + + + + + A method used in seed-based connectivity where an estimate of activation (e.g., beta weights for a particular condition) is extracted for a particular region, then those values are entered into a whole-brain regression analysis across subjects. + + 2024-07-29T18:32:13Z + seed voxel correlation: between-subjects + + + + + + + + + A technique used in functional MRI data set analysis where the response to each event is estimated by fitting a model with separate regressors for each trial.
