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…

Discovery and development of Central Nervous System (CNS) drugs is hampered by high attrition rates.

For Humans of Psychology, students and staff will be put into the spotlight. At our institute prizes are won, exiting research is conducted, knowledge is harnessed, public meeting are organised and open science is highlighted. Take a look behind the scenes.

The lipid matrix of the skin's stratum corneum plays a key role in the barrier function, which protects the body from desiccation. The lipids that make up this matrix consist of ceramides, cholesterol, and free fatty acids, and can form two coexisting crystalline lamellar phases: the long periodicity…

One way for governments to conduct foreign policy and promote national interests is through direct outreach and communication with the population of a foreign country. This is called public diplomacy. Historians such as Helmer Helmers and William T. Rossiter have shown that printed media were already…

Cognitive enhancement reflects the use of any (legitimate) means such as for example food supplements to reach one’s personal best.

Although rarely considered by the pharmaceutical industry or clinicians, 24-hour rhythms in physiology are a factor of potential influence on the pharmacokinetics and pharmacodynamics of drugs.

An international mega-analysis on the neurobiological link between inhibited temperament and social anxiety disorder

.

The drug BIA 10-2474 inhibits fatty acid amide hydrolase (FAAH), a lipase that degrades a specific endocannabinoid. On the basis of this activity, BIA 10-2474 was being developed as a potential treatment for anxiety and pain. In a phase 1 trial of the drug, one subject died, and four others suffered…

Understanding individual differences in self-regulation in boys with ODD/CD on the level of brain, cognition and behavior

We recognize the importance of communicating about our scientic work to the general public and we enjoy doing so. Recently, we received funding from the Pilot fund Science communication by scientists: Appreciated! (with members of Change Leiden) to engage children and adolescents in science communication…

Can birds - like people- ‘see’ voices and learn how to sing by listening and watching?

The Supramolecular & Biomaterials Chemistry group comprises the PIs Alexander Kros, Roxanne Kieltyka, Gregory Schneider and Sander Wezenberg, and is active in the field of self-assembly of amphiphilic peptides and applying them in supramolecular chemistry.

The HOPES study is one of the largest investigations of this kind to date! By studying existing brain scans and data collected form over 4,000 14-25 year olds, the project team hopes to identify specific changes in the brain that make young people vulnerable to suicidal thoughts and behaviours.

The unit Health, Medical and Neuropsychology offers eduction and conducts research on related fields of Health, Medical and Neuropsychology.

Reactions and reaction times in cognitive tasks.

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, and made it to the cover.

The group is involved in training in areas of diagnostic skills, treatment/prevention/intervention, neuropsychological assessment, behavioral observations, clinical interviewing, knowledge of intellectual disability, autism, ADHD, psychosis and aggression.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

The programme of the master specialisation Learning Problems and Impairments studies common learning problems such as dyslexia, hyperlexia and dyscalculia, as well as learning disabilities caused by AHDH, ADD or speech and language disorders. Much attention is also devoted to the relation between brain…

Anne-Laura van Harmelen has received a Vidi grant from the Dutch Research Council (NWO). This talent programme will enable Van Harmelen to research the social and neurobiological mechanisms of resilience in young people with childhood trauma.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

The Institute Council (Instituutsraad - IR) consists of scientists, lecturers, technical support staff and PhD- or MSc-students, all from the IBL. They gather biannually to discuss policies, strategies and other institute matters that may concern any person working or studying at the IBL. These matters…

Previous research has found important inter-individual differences in the pharmacokinetics (PK) of morphine in special populations such as children, the morbidly obese or the critically ill.

The Skin Barrier and Vaccination group is led by Prof. Joke Bouwstra. One of the key functions of the skin is its barrier function, which is located in the uppermost layer of the skin, the stratum corneum. The stratum corneum consists of enucleated dead cells (corneocytes) embedded in a lipid matrix.…

We live in a data-drenched society awash with numbers. An inhabitant of the democratic polis of Athens (5th and 4th centuries B.C.E.) increasingly found himself surrounded by numerical data. This project aims to analyze the communicative functions and the political meaning(s) ascribed to these public…
