What is emotion in human and nonhuman animals? How do emotions get to expression and how do they impact on our interactions, our decisions to trust, distrust or cooperate? Why do we mimic and synchronise affective processes?

N-acylethanolamines (NAEs), which include the endocannabinoid anandamide, represent an important family of signaling lipids in the brain. The lack of chemical probes that modulate NAE biosynthesis in living systems hamper the understanding of the biological role of these lipids.

Industrial manufacturing processes, such as the production of steel or the stamping of car body parts, are complex semi-batch processes with many process steps, machine parameters and quality indicators.

Stimulating the vagus nerve, which provides a direct link between the gut and brain, makes people pay less attention to sad facial expressions. This research study by psychologists Katerina Johnson and Laura Steenbergen is published in the journal Neuroscience.

Gibbs measures, as used in Statistical Mechanics, have a definition that is remarkably similar to the definition ofg-measures, used in dynamical systems.

People who have taken antibiotics in the past three months pay more attention to negative facial expressions, according to research by postdoc Katerina Johnson and assistant professor Laura Steenbergen. This may explain how antibiotics increase the risk of developing depression.

In this episode, we talk with Mariska Kret about the expressions of emotions in humans and animals. Mariska explores the similarities and differences in emotion expression in humans and primates. Want to learn more about Mariska's research and discover why it's important that we learn more about animal…

On the 4th of June, Saskia Lensink successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Saskia Lensink on this achievement!

Making choices is part of life. You make larger or smaller choices in everything you do, and you progress from one choice/decision to the next. All decision-making processes involve three aspects: making a choice, experiencing that choice and reflecting on it.

Each year, Leiden University College The Hague selects 200 students to form a diverse and international student community. In the application roadmap you can see what that process looks like.

‘What a relief,’ was psychologist Mariska Kret’s reaction to the news of her Vidi grant from the national science financier NWO. The grant makes it possible for her to carry out new research into emotions and trust in patients with a social anxiety disorder and patients with autism.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…
