fMRI
Functional magnetic resonance imaging (fMRI) is a brain imaging technology that uses large superconducting magnets to detect blood-oxygen-level-dependent (BOLD) signals as a proxy for neural activity. It is the most widely used non-invasive brain function imaging method, though equipment is expensive and bulky.

fMRI shows that activity in the hypothalamus and fusiform gyrus decreases markedly when sniffing tears.
Modern brain imaging techniques (such as fMRI and PET) have never found any silent brain region.
Using natural fMRI data collected from 7 subjects while listening to narrative stories, the study uses variance decomposition techniques to split the variance in brain activity predicted by LLaMA2-7B and SCRIBE each into shared variance and their own unique variance.
The natural fMRI paradigm used in the study had participants listen to Moth Radio Hour narrative stories rather than presenting isolated words.
Music cognition research uses tools such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to observe in real time which brain regions are activated while listening to music
fMRI indirectly reflects neuronal activity by detecting blood-oxygen-level-dependent (BOLD) signals in the brain, as blood flow increases in regions where neurons are active.
This type of research typically relies on neuroimaging technologies such as functional magnetic resonance imaging (fMRI) to collect brain activity data, which is then decoded using deep learning models.
fMRI relies on large superconducting magnets, with equipment that is expensive, physically bulky, and subject to strict restrictions on subjects.
An fMRI study by Kross and collaborators found that social rejection (such as a romantic breakup) activates neural systems shared with physical pain.
fMRI has limitations including low temporal resolution, spatially blurred signals, and sample sizes typically of 20–50 participants, which means the conclusions of any single study must be interpreted with caution.
