Functional MRI of Sensorimotor Cortex in Preterm Infants

Pediatric Neurology Briefs, 2009
Functional MRI (fMRI) findings in a group of 5 pre-term infants were correlated with a unilateral passive forearm extension/flexion to relate the functional data to structural and behavioral data, in studies at the University of Bonn, Germany; and ...

Hemodynamic profiles of functional and dysfunctional forms of repetitive thinking [PDF]

, 2016
Background: The ability of the human brain to escape the here and now (mind wandering) can take functional (problem solving) and dysfunctional (perseverative cognition) routes.

Changes in Hemodynamic Responses in Chronic Stroke Survivors Do Not Affect fMRI Signal Detection in a Block Experimental Design [PDF]

, 2013
The use of canonical functions to model BOLD-fMRI data in people post-stroke may lead to inaccurate descriptions of task-related brain activity. The purpose of this study was to determine whether the spatiotemporal profile of hemodynamic responses (HDRs)

The Hemodynamic Response to Chronic Anemia [PDF]

Circulation, 1969
To determine whether the hyperkinetic circulatory response to chronic anemia is obligatory and to assess its strength and potential reversibility, the hemodynamic state at rest was assessed (indicator-dilution method) in 24 patients with chronic anemia before and after certain interventions.

Age-related changes in global motion coherence: conflicting haemodynamic and perceptual responses [PDF]

, 2018
Our aim was to use both behavioural and neuroimaging data to identify indicators of perceptual decline in motion processing. We employed a global motion coherence task and functional Near Infrared Spectroscopy (fNIRS). Healthy adults (n = 72, 18-85) were

Hemodynamic Evaluation of Nonselective \u3b2-Blockers in Patients with Cirrhosis and Refractory Ascites [PDF]

, 2018
BACKGROUND:Nonselective \u3b2-blockers (NSBB) have been associated with increased incidence of paracentesis-induced circulatory dysfunction (PICD) and reduced survival in patients with cirrhosis and refractory ascites.

The Supplementary Motor Area Responsible for Word Retrieval Decline After Acute Thalamic Stroke Revealed by Coupled SPECT and Near-Infrared Spectroscopy

Brain Sciences, 2020
Damage to the thalamus may affect cognition and language, but the underlying mechanism remains unknown. In particular, it remains a riddle why thalamic aphasia occasionally occurs and then mostly recovers to some degree.

Activity in the Visual Cortex is Modulated by Top-Down Attention Locked to Reaction Time [PDF]

, 2007
We studied the correlation between perception and hemodynamic activity in the visual cortex in a change detection task. Whenever the observer perceived the location of a change, rightly or wrongly, the blood oxygenation level-dependent signal increased ...

Dobutamine stress MRI in pulmonary hypertension: relationships between stress pulmonary artery relative area change, RV performance, and 10-year survival [PDF]

, 2017
In pulmonary hypertension (PH), right ventricular (RV) performance determines survival. Pulmonary artery (PA) stiffening is an important biomechanical event in PH and also predicts survival based on the PA relative area change (RAC) measured at rest ...
