Functional MRI of Sensorimotor Cortex in Preterm Infants

open access: yesPediatric 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]

open access: yes, 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.

Noise reduction in functional near-infrared spectroscopy signals by independent component analysis [PDF]

open access: yes, 2015
Functional near-infrared spectroscopy (fNIRS) is used to detect concentration changes of oxyhemoglobin and deoxy-hemoglobin in the human brain. The main difficulty entailed in the analysis of fNIRS signals is the fact that the hemodynamic response to a ...

Fast joint detection-estimation of evoked brain activity in event-related fMRI using a variational approach [PDF]

open access: yes, 2012
In standard clinical within-subject analyses of event-related fMRI data, two steps are usually performed separately: detection of brain activity and estimation of the hemodynamic response.

The Hemodynamic Response to Chronic Anemia [PDF]

open access: yesCirculation, 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.

The effects of hemodynamic lag on functional connectivity and behavior after stroke [PDF]

open access: yes, 2015
Stroke disrupts the brain's vascular supply, not only within but also outside areas of infarction. We investigated temporal delays (lag) in resting state functional magnetic resonance imaging signals in 130 stroke patients scanned two weeks, three months
