Disambiguating the role of blood flow and global signal with partial information decomposition [PDF]
, 2019 Global signal (GS) is an ubiquitous construct in resting state functional magnetic resonance imaging (rs-fMRI), associated to nuisance, but containing by definition most of the neuronal signal.

Event-related fMRI and the hemodynamic response [PDF]
Human Brain Mapping, 1998 Event-related functional magnetic resonance imaging (ER-fMRI) methods are allowing a new spectrum of task designs to be explored with brain imaging techniques. Individual trial events can be presented rapidly, in randomly intermixed order, and the hemodynamic responses associated with individual trial events appreciated.

Effect of Local Ropivacaine on Hemodynamic Responses in Craniotomy Patients
Journal of Investigative Surgery, 2018 Background: Increased intracranial pressure (ICP) with hemodynamic is of major concern to anesthesiologists and surgeons in craniotomy surgery. Thus, the management of hemodynamic stability is essential in neuro-anesthesia.

Hemodynamic and metabolic responses to neuronal inhibition
NeuroImage, 2004 Functional magnetic resonance imaging (fMRI) was used to investigate the changes in blood oxygenation level dependent (BOLD) signal, cerebral blood flow (CBF) and cerebral metabolic rate of oxygen consumption (CMR(O(2))) accompanying neuronal inhibition.

Hemodynamic and inotropic effects of endothelin-1 in vivo [PDF]
, 1994 Endothelin-1 (ET-1) is known to have strong vasoactive properties. Contradictory results have been reported with regard to its inotropic effects. This study examined the dose-dependent (500, 1000, 2500, 5000 and 10,000 ng ET-1/kg vs.

Optimized design and analysis of sparse-sampling fMRI experiments
Frontiers in Neuroscience, 2013 Sparse-sampling is an important methodological advance in functional magnetic resonance imaging (fMRI), in which silent delays are introduced between MR volume acquisitions, allowing for the presentation of auditory stimuli without contamination by ...
