The aim of this study was to investigate the effect of acute dopamine agonistic and
antagonistic manipulation on the visual-cue induced blood oxygen level-dependent signal …

The coupling between neurotransmitter-induced changes in neuronal activity and the
resultant hemodynamic response is central to the interpretation of neuroimaging techniques …

Many blood oxygenation level dependent (BOLD) functional magnetic resonance imaging
studies have shown a strong response due to cocaine in brain regions with high …

The blood oxygenation level-dependent (BOLD) responses to visual stimuli, using both a 1-s
long single trial stimulus and a 20-s long block stimulus, were measured in a 4-T magnetic …

To investigate the effect that hyperoxia has on the blood oxygenation level-dependent
(BOLD) response to visual stimulation of human V1, an event-related functional magnetic …

Increases in cerebral blood flow produced by vasoactive agents will increase blood oxygen
level-dependent (BOLD) MRI signal intensity. The effects of such vasodilation on activation …

The sensitivity of gradient echo magnetic resonance imaging (MRI) to changes in cerebral
blood oxygenation (CBO) has been introduced for mapping functional brain activation. Here …

Purpose: To examine the effect of acetazolamide, known to increase cerebral blood flow
(CBF) and glyceryl trinitrate (GTN), known to increase cerebral blood volume (CBV) on the …

We investigate the relationship between the temporal variation in the magnitude of occipital
visual evoked potentials (VEPs) and of haemodynamic measures of brain activity obtained …

Purpose To determine regional differences in the relationship between neuronal activation
and blood oxygenation level‐dependent (BOLD) signal changes. Materials and Methods We …
