Whole-brain models have proven to be useful to understand the emergence of collective activity among neural populations or brain regions. These models combine connectivity matrices, or connectomes, with local node dynamics, noise, and, eventually, transm

They all started with a presentation of the task instruction (1-back or 2-back) for 6 s. Then, each block had a duration of 20 s, where 10 letters (A–Z without mutated vowels, font size 80, font type: Arial and font colour: white) were shown with a task-irrelevant picture in ...

Tests are often used, along with a medical history and neurological exam, to diagnose MS and rule out other causes of symptoms. More than 90% of people with MS have scar tissue that shows up on anMRI scan. A spinal tap can check for abnormalities in the fluid that bathes the brain and...
(Modal power spectra of task-evoked activation mapsinMethods). As an independent replication, we also analyse 10,000 unthresholded activation maps from 1,178 independent experiments available in the NeuroVault repository33, thus providing a comprehensive picture of the diversity of stimulus-evoked...
then taking an action to control something physical using the brain is only a simple if statement away. Just imagine having your BCI connected to a device, you smell a flower and Cortana says, “Do you like how that flower smells? Describe it or take a picture and I’ll tell you what...
Thus, this research introduces a novel hybrid approach that combines handcrafted features with convolutional neural networks (CNNs) to enhance the performance of brain tumor segmentation. In this study, handcrafted features were extracted from MRI scans that included intensity-based, texture-based, ...
Explainability, as defined by the XAI community, highlights technically decision-relevant parts of machine representations and machine models, for example, those parts that contributed to model accuracy in training or to a particular prediction. Importantly in our context, this definition does not refer...
Problems With Movement An injury can affect parts of your brain that help you balance and walk. As a result, you may feel dizzy -- like the room is spinning. Or you could damage the part that helps you see clearly and gauge depth. Physicaltherapyand other rehabilitation can improve your ...
