Analysis of neuroimaging data requires multiple steps where statistics play a crucial role. The MRI methods research group develops new statistical methods that are accurate, transparent and easy to use.

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.  

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…

Mapping the neural mechanisms underlying social motivations of adolescents and adults

A new NMR microscope gives researchers an improved instrument to study fundamental physical processes. It also offers new possibilities for medical science, for example to better study proteins in Alzheimer patients’ brains. Publication in Physical Review Applied.

The old dummy MRI scanner in the LUMC was replaced by a 'new' one from Marktplaats (!) at the beginning of July 2020. This device is used specifically for children and adults suffering from claustrophobia, and to introduce the elderly to the scanner.

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…

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

This dissertation examines what network in the human brain is involved in the perception of prosody and whether activity within this network is modulated by the personality trait alexithymia.

The updated MRI scanner at the Leiden Institute for Brain and Cognition (LIBC) will become operational on 29 September. The new version is faster and better than the current model.

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…

Waarom is empirisch-juridisch onderzoek van belang voor de rechtspraktijk en het wetenschappelijke onderzoek? Op die vraag kregen masterstudenten van de afstudeerrichtingen civiel recht, ondernemingsrecht en financieel recht antwoord tijdens het congres over empirisch-juridisch onderzoek en het privaatrecht…

In October 2019, OSCL organised a Hackathon on the ins and outs of MRI datasharing

On Tuesday 14 February 2017 defended Kees van Gageldonk his doctoral thesis ‘Op zoek naar onderzoek.
