Understanding brain function relies on identifying spatiotemporal patterns in brain activity. In recent years, machine learning methods have been widely used to detect connections between regions of interest (ROIs) involved in cognitive functions, as measured by the fMRI technique. However, it's essential to match the type of learning method to the problem type, and extracting the information about the most important ROI connections might be challenging.

Article Synopsis
- The study looked at how some people with schizophrenia (SZ) or bipolar disorder (BD) might have trouble learning motor skills without thinking about it (like tapping to a rhythm).
- It involved 30 patients from each group and 30 healthy people, and they used brain scans to see how different parts of the brain connected while the patients weren’t doing anything.
- The results showed that the way these brains connected didn’t affect their ability to learn these skills, meaning that learning these motor tasks is independent of those brain network activities.
Introduction: Schizophrenia (SZ) and bipolar disorder (BD) share common clinical features, symptoms, and neurocognitive deficits, which results in common misdiagnosis. Recently, it has been suggested that alterations within brain networks associated with perceptual organization yield potential to distinguish SZ and BD individuals. The aim of our study was to evaluate whether functional connectivity (FC) of the dorsal attention network (DAN) may differentiate both conditions.

Although the recent rise in the use of magnetic resonance imaging (MRI) has enabled investigations into the macroscopic correlates of the diurnal brain processes, neuroanatomical studies are scarce. The current work investigated how time-of-day (TOD) impacts white (WM) and grey matter (GM) volumes using voxel-based morphometry (VBM) in a large dataset ( = 72) divided into two equal, comparable subsamples to assess the replicability of effects.

Introduction: Our previous studies identified a paradoxical implicit motor learning curve in schizophrenia (SZ) and bipolar disorder (BD) patients. This study aimed to verify whether those previously observed deficits may be captured by a new version of the ambidextrous serial reaction time task (SRTT), prepared for use in the MRI.
Methods: This study involved 186 participants.
