Unconstrained day-to-day activities are difficult to quantify and how the corresponding movements shape the brain remain unclear. Here, we recorded all touchscreen smartphone interactions at a sub-second precision and show that the unconstrained day-to-day behavior captured on the phone reflects in…

During the course of drug discovery translational steps are made.

The “harpe organisée”, 1720-1840: Rediscovering the lost pedal techniques on harps with a single-action pedal mechanism, is the title of Maria Christina Cleary's PhD thesis. This is the first monographic study on harp pedal techniques, tracing the historical way to pedal on the early pedal harps with…

A quarter of all Dutch students suffer burn-out symptoms, and an even greater percentage regularly experience emotional exhaustion and tiredness. At a symposium on 7 May students were given tips for handling stress.

Our mission is to improve the description, prediction, understanding and the prevention and treatment of mood disorders, including unipolar and bipolar depression, as well as suicidal thoughts, feelings, and behaviors. To tackle this ambitious mission, we focus on several research streams.

An e-coaching programme helps people with chronic kidney disease, particularly in areas that patients themselves want to work on. ‘A healthy lifestyle is important for patients with kidney disease: it can slow down the loss of kidney function and there will be fewer complications,’ Katja Cardol explains…

Stress and overwork are massive problems today, but relatively little is known about stress factors in the past. With a look at the deep history of stress, Sarah Schrader hopes to get a better understanding of the human stress experience. Her project application received an NWO XS grant.

Drug-target binding kinetics determine the time course of the central event in pharmacotherapy: Drug-target interaction.

The more we learn about a (neuro-)psychological or physical disorder and the related behavioral factors, the better we can not only identify them, but also treat them. It is therefore important that recent insights about (neuro-)psychological problems and related behavioral factors are incorporated…

Since itch and pain can be very burdensome, especially when individuals suffer from (either of) these symptoms chronically, it is important to know the factors by which these sensations are influenced. It becomes more and more clear that psychological factors play an important role in the experience…

People who are often stressed can feel calmer by making certain adjustments to their breathing. Possibly this also positively affects concentration and attention. Psychologist Roderik Gerritsen studied the effects of breathing differently for the first time, and explains them. Gerritsen receives his…

Aukje Nauta's professorship at Leiden University has been extended for another five years. She will further research how connectedness in the workplace helps people to be their full self and perform better.
