"brain task" is a grammatically correct and usable phrase in written English.
It refers to an activity or assignment that requires mental effort and involves using one's cognitive abilities. I have a difficult brain task to complete for my psychology class tomorrow. He was given a series of brain tasks to assess his problem-solving skills. During the job interview, the candidate was asked to demonstrate their ability to handle complex brain tasks under pressure. Completing crossword puzzles and Sudoku is a great way to challenge your brain and improve your brain task performance.
This is what appears to happen in the brain when it is under continuous stress: it essentially builds up the part of the brain designed to handle threats, and the part of the brain tasked with more complex thought takes a back seat.
Functional MRI (fMRI) is available in most centers and could address several brain tasks through the selection of paradigms tested.
We used T2 images for the whole-brain task because this is most heavily relied upon for brain tumour detection.
Therefore, we propose a hierarchical Bayesian framework to detect both hyper- and hypo-synchronous functional communities within whole-brain task fMRI data.
Stimuli for the whole-brain task consisted of 60 T2 brain MRI images from one patient with a right medial temporal lobe intrinsic tumour (see Fig. 1 for example slices).
The first was a whole-brain task, which consisted of 60 consecutively presented slices from one patient; the second was an independent-slice detection task, which consisted of 32 independent slices from five different patients.
A limitation of the whole-brain task was that each slice was presented for a fixed 1500-ms duration which does not reflect clinical practice in which clinicians can scroll freely through the image in any direction at their desired speed.
In the whole-brain task, eye-gaze data was recorded while participants sequentially viewed 60 slices of a patient's brain MRI and in the independent-slice task, both eye-gaze data and performance measures were recorded when participants inspected 32 brain MRIs (16 tumorous; 16 healthy).
The whole-brain task revealed that scanning patterns were more similar for Run 1 than Run 2. One interpretation is that scanning patterns in Run 1 were largely driven by saliency which supports models of visual saliency whereby fast and primitive bottom-up processes bias the observer towards the most salient stimuli in the early stages of exposure (Parkhurst, Law, & Niebur, 2002).
