blood oxygen level dependent

blood ox·y·gen lev·el de·pen·dent

(blŭd ok'si-jĕn lev'ĕl dĕ-pen'dĕnt)
A functionalMRI technique that uses the differences in magnetic susceptibility between oxyhemoglobin and deoxyhemoglobin to image areas of activated cerebral cortex.

The study participants were shown a series of short videos featuring either sexually explicit content or sports whilst their brain activity was monitored using functional magnetic resonance imaging (fMRI), which uses a blood oxygen level dependent (BOLD) signal to measure brain activity.
Using blood oxygen level dependent (BOLD) functional MRI (fMRf) to determine neuronal activity following forepaw or hindpaw stimulation, MPC-treated animals showed a significant increase in neuronal activity compared with conlrols in both the infarct area (p less than 0.
Using blood oxygen level dependent (BOLD) functional MRI (fMRI) to determine neuronal activity following forepaw or hindpaw stimulation, MPC-treated animals showed a significant increase in neuronal activity compared with controls in both the infarct area (p less than 0.
This characteristic is known as the blood oxygen level dependent (BOLD) effect.
During a simple finger-tapping task, changes were assessed in cerebral blood flow, cerebral metabolic rate of oxygen consumption, and blood oxygen level dependent mapping within a subcortical region, the lenticular nuclei of the basal ganglia.
It uses a imaging technique known as blood oxygen level dependent or BOLD.
In addition, there was a reduction in parietal lobe blood oxygen level dependent (BOLD) signal intensity during mental rotation, potentially indicating less neuronal recruitment being required to complete tasks.
