A neuro-ecological perspective on adolescent prosocial development

The life cycle of comets near the star Beta Pictoris is similar to that of comets in our own solar system. This is the conclusion of a team of astronomers from the Netherlands, France and Brazil. It seems that, just like in our own solar system, there are fewer comets as the star gets older. The researchers,…

Together with a large international team of scientists, researchers Peter van Bodegom and Nadia Soudzilovskaia of the Leiden Institute of Environmental Sciences (CML) have created maps of variability in plant trait distribution across the globe. The new maps have been published in Proceedings of the…

ADHD & ME aims to explore how enhancing self-esteem can break the relation between ADHD symptoms and comorbid disorders, such as anxiety and depression. In this study we assess the effectiveness of a Cognitive Behavioural Therapy (CBT) program called Competitive Memory Training (COMET) for improving…

An assessment approach that tailors to children’s instructional needs

Spatial technology such as virtual reality can help patients who have difficulty with spatial cognition, for instance if they keep on losing their way. In her inaugural lecture, neuropsychologist Ineke van der Ham will talk about the importance of avatars, the patient experience and room for innovat…

How do practice and theory reinforce one another in neuroscience? Professor Birte Forstmann’s inaugural lecture on 2 October will be about building interdisciplinary bridges between cognitive neuroscience and cognitive models. Her approach may lead to brain research with fewer side-effects for patie…

Regular users of cannabis are less aware of their own mistakes, and they are not good at creative thinking. This is the conclusion drawn by psychologist Mikael Kowal from his research on the effects of cannabis. PhD defence 6 October.

This work is dedicated to interpreting in cohomological terms the special values of zeta functions of arithmetic schemes.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

Professor Mariska Kret has received the Mercator Sapiens Stimulus, a new science prize from the Royal Holland Society of Sciences and Humanities (KHMW). The prize consists of a sum of 1m euros.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Our everyday life consists of all sorts of spatial processes: we find our way to work, remember where we left our keys, and are able to pick up our cup of coffee. We study how the human brain processes such spatial processes. From a clinical perspective, we are interested in how acquired brain damage…

Cognitive neuroscience gives us a glimpse into our brain activity; it allows us to learn more about ourselves. Or do brain scans actually not say very much about who we are? Philosopher Annemarie van Stee examines four myths about neuroscience and self-understanding.

A portrait can inspire, intimidate or reassure the viewer. Leiden University has many portraits of professors and students, from the foundation of the University to the present day. What purpose do these portraits serve? The 'Facing Inspiration' exhibition in the Oude UB is about this question.
