WebOct 10, 2024 · However, gathering large fMRI datasets for learning is a difficult task. Furthermore, network interpretability is unclear. To address these issues, we utilize multitask learning and design a novel RNN-based model that learns to discriminate between classes while simultaneously learning to generate the fMRI time-series data. WebOct 1, 2024 · This work investigates the possibility to perform self-supervision from healthy subject data without the need of image annotation, followed by transfer learning from the models trained on some pretext task, and the result of self- supervision is shown to bring about 3% increase in performance.

WebMost fMRI experiments study brain processes lasting a few seconds, with the study conducted over some tens of minutes. Subjects may move their heads during that time, and this head motion needs to be corrected for. So does drift in the baseline signal over time. Boredom and learning may modify both subject behavior and cognitive processes. WebTo obtain both types of imaging, a patient lies still in a long, tubular magnet, which uses the body’s magnetic properties to create highly detailed images. While an MRI scan allows doctors to examine a patient’s organs, tissue, or bones, “an fMRI looks at the function of the brain,” Dr. Zucconi explains.
WebWhile there is no meaningful dispute that the hippocampus is required for conscious learning and memory formation, it may serve a broader function. Several studies have been recently published suggesting that the hippocampus is also implicated in certain implicit tasks (Chun and Phelps 1999; Ryan et al. 2000; Greene et al. 2006). WebApr 12, 2024 · Despite widespread use of machine learning methods for rs-fMRI classification, the use of machine learning techniques in tDCS-fMRI studies is limited and …
WebApr 12, 2024 · Machine learning methods have been explored to characterize rs-fMRI, often grouped in two types: unsupervised and supervised [ 24 ]. Unsupervised methods focus on understanding healthy brain and its dynamics such as matrix decomposition and clustering to identify brain functional networks [ 25, 26 ]. WebSep 21, 2024 · Functional magnetic resonance imaging (fMRI) measures indirect, hemodynamic (blood oxygen) consequences of neural activity. As a result, blood oxygen level dependent (BOLD) fMRI signal can be influenced by other physiological processes that modulate blood oxygenation [], in addition to neural activity.Two major physiological …
