Towards nano-MRI
By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.

Archeologisch onderzoek langs de Rikkert in Enkhuizen
Tot voor kort was de kartering van oppervlaktevondsten de geijkte manier om het in de bronstijd bewoonde gebied in West-Friesland in kaart te brengen. In dit rapport gebaseerd op archeologisch onderzoek in 2012-2015 wordt uiteengezet wat de relatie tussen de oppervlaktevondsten en de aan- en afwezigheid…

Het gebruik van drones; een verkennend onderzoek naar onbemande luchtvaartuigen
Unmanned aerial vehicles (UAVs), often referred to as drones, have become easy and inexpensive to buy, and it is generally expected that the use of drones by private individuals, businesses and public authorities will increase tremendously in the coming years. This raises questions as to what is technologically…

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…

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.

G.F. Stout and the Psychological Origins of Analytic
The philosopher and psychologist G.F. Stout was the teacher of Moore and Russell around 1894. This book shows that Stout's ideas have played a role in Moore and Russell's development from their early idealism towards analytic realism, where Stout's ideas often find their origin in early phenomenolog…

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…

Novel detection method for iron in Alzheimer’s brain
For many years, scientists have observed a correlation between Alzheimer’s disease and a surplus of iron in the brain. However, a causal link between the two has not been proven yet. We lack knowledge concerning the specific form of iron that is involved in the development of neurodegenerative diseases.…

Legal decision making in liability law and financial regulation
The starting point for this research project is the notion that the human brain is susceptible to all kinds of fallacies and biases that affect our perceptions and influence our reasoning outside of our conscious awareness. Indeed, most people think they are merely observing facts and that they process…

Train your brain!
Neuroimaging research has greatly advanced our insights on how the brain is organized. Now is the time for the next step: Imagine what would be possible when we cannot only map brain-functioning, but use neuroimaging to voluntarily regulate brain-activity!
