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…

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

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…

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.

Professor of Radiology Andrew Webb and his collaborative partner Johnes Obungoloch from Uganda have won the 2023 Huibregtsen Prize.

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 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…

Together with researchers from over the world, the ENIGMA-Anxiety Working Group endeavors to unravel the neurobiology of anxiety disorders and related constructs.

Kan artificiële intelligentie (AI) helpen om subtiele veranderingen in de gewrichten op te merken op MRI-beelden van patiënten met reumatoïde artritis? Die vraag gaan Leidse wetenschappers beantwoorden dankzij een subsidie van de Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO).

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…

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

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…

How do you get citizens more involved in energy transition projects? This is the central question of the new transdisciplinary research project EmPowerEd. As a consortium partner, Leiden University is focusing on effective and inclusive collaboration between citizens, municipalities and industry.

Zou je graag een hoofdstuk uit je proefschrift in informele setting willen bespreken? Heb je een onderzoeksidee dat je graag zou voorleggen aan vakgenoten? Neem dan contact op met ozsmed@hum.leidenuniv.nl. De Onderzoekschool organiseert sinds kort een seminarreeks waarin dergelijke onderwerpen in een…

Leiden University Medical Center (LUMC), Leiden University and Philips are jointly receiving over 2 million euros from NWO to set up an artificial intelligence (AI) lab. The aim of this lab is to accelerate and improve MRI scans with AI. This is great for patients, and it helps make MRI more accessi…

Professor Andrew Webb has been appointed Simon Stevin Master 2017 by the Netherlands Organisation for Scientific Research, an award that carries a prize of 500,000 euros. Webb, who is Professor of MRI Physics at Leiden University Medical Center (LUMC), will use this funding to focus on developing new…

Mirjam Sombroek-van Doorm heeft in samenwerking met de interventie ‘Nu Niet Zwanger’ een derde geldstroomonderzoek gegund gekregen. Het betreft advisering over gezondheidsrechtelijke kwesties binnen de betreffende interventie.

Together, Leiden University Medical Center (LUMC), Leiden University and Philips are one of the 17 AI labs within the ROBUST consortium that will receive support from the Dutch Research Council (NWO). The aim of this collaboration is to use artificial intelligence to speed up MRI scans.

Een samenwerking tussen het Leids Universitair Medische Centrum (LUMC), de Universiteit Leiden en Philips ontvangt financiering van wetenschapsfinancier NWO om MRI-scans te versnellen. Deze drie partijen vormen samen een van de 17 AI-labs die onder de naam ROBUST voor een periode van 10 jaar NWO-steun…

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.…

Do objectively correct solutions to ethical dilemmas exist? Or is ethics always a matter of your opinion against my opinion? How do you know what to do? What kind of thing is ethics anyway? Can you be an expert in ethics?

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…
