brain imaging

The method, dubbed “DIANA,” could transform neuroscientists’ understanding of how the brain works, researchers say—though for now, it’s only been tested in anesthetized mice.

By linking blood flow patterns to bioelectric signals in the brains of sleeping volunteers, scientists are studying the order in which brain regions fall asleep and wake up.

While much is known about how the brains of English speakers process language, research has neglected people who speak other languages. The Scientist spoke with one of the authors of a study that seeks to change that.

Study finds that, contrary to what other research has found, a popular meditation course does not appear to alter brain structure.

The size and complexity of cephalopod brain structures differ depending on the habitats the creatures occupy, a study finds.

Researchers who spoke with Spectrum say that while brain imaging tools have their limitations, they still hold promise in helping to unlock the brain’s secrets. 

Imaging reveals how cyclical patterns of brain activity differ between conscious and unresponsive individuals.

Researchers could anticipate which way an eight-day-old zebrafish will flick its tail based on brain activity 10 seconds earlier.

A woman whose DNA suggested she’d develop early-onset dementia staved off cognitive decline for decades.

MRI scans from more than 800 incarcerated men pinpoint distinct structural features of people who have committed homicide, compared with those who carried out other crimes.

A growing body of evidence supports the theory that neural hyperactivity and hyperconnectivity precede the pathological changes that lead to neurodegeneration.

Researchers are developing a variety of approaches for clearing neural tissue to get a better view of the brain’s circuitry.

A study hints that it might be possible to diagnose chronic traumatic encephalopathy, a neurodegenerative disease associated with frequent head injuries, while patients are still living.

Researchers engineered a system for bioluminescent imaging that is as much as 1,000 times stronger than existing methods.

Researchers create a program that can use fMRI data to identify which musical pieces are in participants' heads.  

Using machine learning, researchers have created extensive maps of the neuronal circuits associated with social and locomotion behaviors in the fruit fly. 

The white matter tracts that wind throughout this microetching are based on diffusion spectrum imaging data from a human brain, realistically portraying the circuits found within a sagittal brain section.

Infants born to mothers who were infected with the virus during pregnancy—including babies who do not show signs of microcephaly—may experience other birth defects.
