[Google Scholar] Web1 de mar. de 2007 · The first step in fMRI statistics is almost invariably to create a thresholded statistical map, showing which regions are ‘activated’ above some particular threshold. For simple comparisons, it is often sufficient to stop there and simply report the results of the thresholded map.

MRI (magnetic resonance imaging) provides a map of the brain – how it looks at a set moment in time. This structural information can be useful for determining how the sizes of certain brain areas compare across people, or if there is something abnormal about a particular brain (a tumor for example). Ver mais EEG (electroencephalography)measures the electrical activity of our brain via electrodes that are placed on the scalp. It tells us, from the surface measurements, how active the brain … Ver mais The brain is an electrical system – all of our thoughts (conscious or otherwise) are generated through a network of neurons, that send signals to each other with the help of electrical … Ver mais If I want to move my right arm, a few things need to happen.

Since it was introduced a decade ago, functional magnetic resonance imaging (fMRI) has come to dominate research on the human brain. However, fMRI maps are based on secondary metabolic and hemodynamic events that follow neuronal activity, and not on the electrical activity itself. Therefore, the representation provided by fMRI cannot ...
