When we daydream or revisit memories, a large group of regions within our brain “lights up,” or becomes more active. It's referred to as the Default Mode Network (DMN) because it is more active when ...

A new study shows how neurochemicals can influence blood vessels. The findings may change how researchers interpret results from functional magnetic resonance imaging studies. The brain is an ...

Researchers have learned a lot about the human brain through functional magnetic resonance imaging (fMRI), a technique that can yield insight into brain function. But typical fMRI methods may be ...

Functional magnetic resonance imaging (fMRI) is a noninvasive technique used to detect brain activity by measuring changes in blood flow to different areas of the brain. It’s been used for the last ...

The UK researchers “ used fMRI to detect brain activity when volunteers were looking at different images with their left and right eyes. As focus and attention switched between eyes, different areas ...

Neuroimaging techniques, like functional magnetic resonance imaging (fMRI), are not able to directly measure neuronal activity. To address this knowledge gap, a team has created a novel experimental ...
