Visual working memory not as specialized in the brain as visual encoding, study finds
Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance at faces, and another region called ...

Gene variant leads to better memory via increased brain activation
Carriers of the so-called KIBRA T allele have better memories than those who don't have this gene variant. This means we can reject the theory that the brain of a non-bearer compensates for this. This is shown by researchers ...

Functional magnetic resonance imaging
Functional MRI or functional Magnetic Resonance Imaging (fMRI) is a type of specialized MRI scan. It measures the haemodynamic response related to neural activity in the brain or spinal cord of humans or other animals. It is one of the most recently developed forms of neuroimaging. Since the early 1990s, fMRI has come to dominate the brain mapping field due to its low invasiveness, lack of radiation exposure, and relatively wide availability.
