Resting state fMRI (rs-fMRI or R-fMRI), also referred to as task-independent fMRI or task-free fMRI, is a method of functional magnetic resonance imaging (fMRI) that is used in brain mapping to evaluate regional interactions that occur in a resting or task-negative state, when an explicit task is not being performed.
Last.fm is a music website founded in the United Kingdom in 2002. Utilizing a music recommender system known as "Audioscrobbler," Last.fm creates a detailed profile of each user's musical preferences by recording the details of the tracks they listen to, whether from Internet radio stations or from the user's computer or portable music devices.
With regard to the brain and brain function it is seldom that a particular brain region is activated solely by one cognitive process. [87] Some suggestions to improve the legitimacy of reverse inference have included both increasing the selectivity of response in the brain region of interest and increasing the prior probability of the cognitive ...
Functional magnetic resonance imaging (fMRI), is the medical imaging technique used to measure the haemodynamic response of the brain in relation to the neural activities. [12] It is one of the most commonly used devices to measure brain functions and is relatively inexpensive to perform in a clinical setting.
Representation of the stages of processing in a typical reaction time paradigm. Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations.
The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it.. In a study of mice, researchers at the Allen Institute identified ...
Through a process called the haemodynamic response, blood releases oxygen to active neurons at a greater rate than to inactive neurons. This causes a change of the relative levels of oxyhemoglobin and deoxyhemoglobin (oxygenated or deoxygenated blood ) that can be detected on the basis of their differential magnetic susceptibility .
The study’s findings, based on a VO2 max test, showed that individuals who were more fit performed better across five domains of cognitive ability, including memory and executive functioning.
