Previous glucocorticoid treatment in childhood and adolescence is associated with long-term differences in subcortical grey matter volume and microstructure

open access: yesNeuroImage: Clinical, 2019
Background: Glucocorticoids are widely used in the treatment of several pediatric diseases with undisputed disease-related benefits. Perinatal exposure to high levels of glucocorticoids can have long-term adverse cerebral effects.

Functional MRI with active, fully implanted, deep brain stimulation systems: Safety and experimental confounds [PDF]

open access: yes, 2007
We investigated safety issues and potential experimental confounds when performing functional magnetic resonance imaging (fMRI) investigations in human subjects with fully implanted, active, deep brain stimulation (DBS) systems.

Functional asymmetry for auditory processing in human primary auditory cortex [PDF]

open access: yes, 2003
Structural asymmetries in the supratemporal plane of the human brain are often cited as the anatomical basis for the lateralization of language predominantly to the left hemisphere.

Micro-magnetic resonance imaging study of live quail embryos during embryonic development [PDF]

open access: yes, 2011
Eggs containing live Japanese quail embryos were imaged using micro-magnetic resonance imaging (μMRI) at 24-h intervals from Day 0 to 8, the period during which the main body axis is being laid down and organogenesis is taking place.

Boosting BOLD fMRI by K-Space density weighted echo planar imaging [PDF]

open access: yes, 2013
Functional magnetic resonance imaging (fMRI) has become a powerful and influential method to non-invasively study neuronal brain activity. For this purpose, the blood oxygenation level-dependent (BOLD) effect is most widely used. T2* weighted echo planar

The spinal cord is never at rest

open access: yeseLife, 2014
Even when we are at rest, our spinal cords show spontaneous, yet well organised, fluctuations of activity that might reflect sensory and motor networks.

Amygdala-hippocampal involvement in human aversive trace conditioning revealed through event-related functional magnetic resonance imaging [PDF]

open access: yes, 1999
Previous functional neuroimaging studies have characterized brain systems mediating associative learning using classical delay conditioning paradigms.

Real-time imaging of the medullary circuitry involved in the generation of spontaneous muscle sympathetic nerve activity in awake human subjects [PDF]

open access: yes, 2008
In order to understand the central neural processes involved in blood pressure regulation we recorded muscle sympathetic nerve activity (MSNA) via a tungsten microelectrode in the common peroneal nerve while performing functional Magnetic Resonance ...

The multisensory attentional consequences of tool use : a functional magnetic resonance imaging study [PDF]

open access: yes, 2008
Background: Tool use in humans requires that multisensory information is integrated across different locations, from objects seen to be distant from the hand, but felt indirectly at the hand via the tool.

No difference in postprandial mesenteric blood flow between healthy younger and elderly individuals

open access: yesScientific Reports
We recently used phase-contrast magnetic resonance imaging (PC-MRI) to demonstrate an attenuated postprandial blood flow response in the superior mesenteric artery (SMA) in patients with Parkinson's disease compared to age- and sex-matched healthy ...
