Or they can look broadly at the whole brain using magnetic resonance imaging.
For the new research, published in the Archives of General Psychiatry, David Tolin of the Institute of Living in Hartford, Connecticut, recruited 107 people for brain scans using functional magnetic resonance imaging (fMRI).
It's based on his work using functional magnetic resonance imaging brain scans that first demonstrated that, when people are asked to imagine themselves in retirement, the parts of their brains that usually "light up" when they think about themselves don't light up at all.
Magnetic resonance imaging and brain biopsy were consistent with fulminant demyelinating encephalomyelitis with enhancing parenchyma and leptomeninges.
FORBES: Researchers Highlight Warning Signs On Adult Stem Cell Treatments
Daniel Langleben, of the University of Pennsylvania, in Philadelphia, uses a brain-scanning technique called functional magnetic-resonance imaging to probe his subjects' honesty.
Then at about age 73, 700 study participants were given a magnetic resonance imaging (MRI) brain scan.
WSJ: Exercise Might Beat Puzzles for Protecting the Aging Brain
They use functional magnetic resonance imaging scans to measure brain responses.
The researchers used fMRI (functional magnetic resonance imaging) scans to monitor brain activity in 15 people with autistic spectrum disorders and 15 without.
The team used a technique called magnetic resonance spectroscopy (MRS) to examine brain function in eight patients with serious lung disease.
In 2000, Knutson published the first paper using magnetic resonance imaging to photograph what goes on in the brain as people deal with money.
But studies using fMRI (functional magnetic resonance imaging) can show what's happening in the brain.
She has created a software program that uses data from magnetic resonance imaging scans to simulate how fast a patient's brain tumor is likely to spread.
Later studies with magnetic resonance imaging machines showed that the amygdala, the part of the brain responsible for memory and emotional reactions, didn't fire even when older people were shown disturbing images.
To study the neurology of tickling, Dr Blakemore and her team stuck volunteers into a magnetic-resonance-imaging machine (which monitors oxygen flow to the brain, and thus indicates the amount of activity in that organ's various parts).
Researchers at 11 institutions are mapping the largest conduits among brain regions by combining four imaging techniques, including a new method called diffusion magnetic-resonance imaging that allows researchers for the first time to accurately map the white matter of nerve fibers.
Using a technique called functional magnetic resonance imaging (fMRI), the researchers were able to record the brain's activity in response to internal and external stimuli such as eating and drinking.
Saygin and colleagues published a study last year using functional magnetic resonance imagining (fMRI), looking at what's happening in the brain that might explain the uncanny valley phenomenon.
Four different studies done in the past decade using MRI (magnetic resonance imaging) all found a slight reduction in the size of four regions of the brain: the corpus callosum, the basal ganglia, the frontal lobes, and the cerebellar vermis.
