Catecholaminergic Neuromodulation Shapes Intrinsic MRI Functional Connectivity in the Human Brain
The factors that dynamically sculpt the inter-regional correlation of brain patterns are poorly understood. Here, we test the hypothesis that they are shaped by the catecholaminergic neuromodulators norepinephrine and dopamine.

Mechanism MRI amplifying agents explored
Special amplifying agents can make MRI scanners and NMR techniques hundreds of times more sensitive. Leiden physicists have now found a method to test their efficiency. More sensitive MRI scans could for example improve our understanding of cystic fibrosis or Parkinson’s disease. Publication in PCCP…

Neural correlates of vocal learning in songbirds and humans: cross-species fMRI studies into individual differences
Vocal learning is a trait shared by songbirds and humans. It is also a trait that is restricted by the brain rather than by a species' vocal apparatus. In this dissertation, functional MRI is employed in both species in order to explore potential common neural mechanisms underlying the ability to develop…

Boudewijn Lelieveldt: 'AI can help, but not replace, doctors and other healthcare providers'
‘I would never want to be treated by a computer,’ says Boudewijn Lelieveldt, Head of Radiology at the Laboratory for Clinical and Experimental Image Processing and Medical Delta professor in the Bioinformatics group at Delft University of Technology. No matter how intelligent a system, we have to continue…

Serge Rombouts: 'AI is learning from brain scans and helping find a diagnosis'
Serge Rombouts is a physicist whose PhD thesis was about functional MRI (fMRI). This visualises activity in regions of the brain. The appealing images of glowing brain regions that emerge from the computer are the result of calculations. According to Rombouts, this isn’t proper artificial intelligence.…

Physicists link specific iron forms to Alzheimer’s
There have been indications for decades that there is a link between increased iron levels in the brain and Alzheimer’s disease. Leiden physicists find this connection as well, thereby now making a distinction between different forms of iron. They identify specific iron forms that increase in Alzheimer’s…

Brain research shows punishing is more rewarding than helping
Just imagine: you see someone being treated unfairly. Do you find it more rewarding to help the victim or punish the perpetrator? Research by Leiden psychologist Mirre Stallen indicates that punishing is more rewarding. Publication in JNeurosci.

Polyfluorinated bis-styrylbenzenes as amyloid-beta plaque binding ligands
Detection of cerebral beta-amyloid (Abeta) by targeted contrast agents remains of great interest to aid the in vivo diagnosis of Alzheimer's disease (AD). Bis-styrylbenzenes have been previously reported as potential Abeta imaging agents.
