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…

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.…

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.

Right brain hemisphere also important for learning a new language
Novel language learning activates different neural processes than was previously thought. A Leiden research team has discovered parallel but separate contributions from the hippocampus and Broca's area, the learning centre in the left hemisphere. The right hemisphere of the brain also seems to play…

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…

You make your best friends in your late adolescence
What happens in young people's brains when they win money for someone else? Psychologist Elisabeth Schreuders has shown that the brain responds differently according to the type of friendship and that the response is strongest with stable relationships later in adolescence. PhD defence on 6 March.

Best friends forever? How the adolescent brain reacts to good friends
During adolescence, some young people have stable best-friend relationships, while others change best friends frequently. Developmental psychologist Lisa Schreuders has studied the brains of young adolescents: ‘It seems that friendships in your early years can have consequences for your friendships…
