Sentences with phrase «detecting changes in blood flow»

To study how music preferences might affect functional brain connectivity — the interactions among separate areas of the brain — Burdette and his fellow investigators used functional magnetic resonance imaging (fMRI), which depicts brain activity by detecting changes in blood flow.

Dr. Aron and colleagues based their study's conclusions on a neuroimaging study using functional magnetic resonance imaging (fMRI) scanning that measures brain activity by detecting changes in blood flow.

Using a functional MRI (fMRI) scanner, which detects changes in blood - flow patterns, the scientists monitored what was happening inside subjects» brains.

The new research also gives insight into the mechanisms underlying the use of functional magnetic resonance imaging to detect blood flow changes in the brain.

He used functional magnetic resonance imaging (fMRI), a means of measuring brain activity by detecting blood flow changes inside the brain, to measure differences in the strengths of communications between brain regions.

The fast fMRI was able to detect the subtle and very rapid oscillations in cerebral blood flow in the brain's visual cortex as the volunteers observed the changing pattern.

NIRSIT is a device based on the near - infrared spectroscopy principle, which (a) utilizes light to detect hemodynamic changes in the cerebral blood flow and (b) visualizes brain activation regions in the prefrontal area of the brain in real time.

I am proposing a demanding criterion: that you be able to detect abnormalities in patients beforehand by such brain - imaging techniques as functional MRI [which measures blood flow in the brain], and then use imaging to see whether or not there is a change in those markers for the disease as the therapy progresses.

The fMRI scan does this by detecting indirect changes in the brain's blood flow in response to changes in electrical signalling during the stimulus.

It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity — when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area.
