Women are more often diagnosed with depression, whereas ADHD is much more frequently detected in men. And there are other more striking differences. What role does the brain play in mental health and what is the influence of the environment? For answers to these questions, listen to the ‘(Un)gendered…

Few researchers see potential in research on glioblastoma, an incurable brain tumour. Alexander Kros brought together colleagues who are up to the challenge. European research funder ERC recently made 10.6 million euros available, a year earlier NWO provided 3 million euros. ‘In six years, we certainly…

For their research many neuropsychologists use the brain scanners at the LUMC. At the start of the pandemic, the rules for visiting the hospital became stricter and a large amount of psychology research looked as though it would fall through. Thanks to good protocols the researchers can now pick up…

There seem to be genes that influence how our brains develop over time. A large international consortium has discovered this with an extensive study. The results of the study were recently published in Nature Neuroscience.

On Sept. 29, Lara Wierenga, together with graphic designer Dirma Janse, presented their new book Atlas of our Brain. In the presence of fellow scientists and other interested parties, they shared some of the stunning illustrations and mind-boggling facts that can be found in the book.

Maaike Kempes believes more attention should be paid to non-congenital brain injuries in suspects. This may partly explain their criminal behaviour.

The brain structure of young people with conduct disorder differs significantly from that of their typically developing peers. This is the conclusion of an international study that analysed more than two thousand MRI scans, recently published in The Lancet Psychiatry. Dr Moji Aghajani, one of the principal…

It may seem as though adolescents do as they please, but they are more sensitive to their parents’ opinions than they would appear. The adolescent brain reacts strongly to parental criticism or praise. These are the results of a study by an interdisciplinary research group of psychologists and neuroscientists…

A unique multicenter study, including about 3,500 youth between 10 and 25 years old from across the globe, shows that artificial intelligence - specifically machine learning - is able to identify individuals with anxiety disorders based on their unique brain structure.

Researchers at the Universities of Amsterdam (Uva) and Leiden together with the Netherlands Cancer Institute and Oncode Institute have received a €10,6 million ERC Synergy Grant to develop innovative therapeutic approaches to target glioblastoma. This is a deadly primary brain tumour for which no curing…

Marlien van Mever delved into the analysis of tiny samples, cerebrospinal fluid from transgenic mouse models for example. She validated methods that can now be used to study brain diseases such as migraine and epilepsy. Van Mever will receive her PhD on 14 June.

Parents appear to be extremely sensitive to feedback they receive about their child. Just how sensitive depends on the (‘rose-tinted’) glasses through which they look at their child. All this can be seen in the brain. Neuroscientist Lisanne van Houtum and her Leiden colleagues published on this issue…

'With this artwork, I want to give the audience a glance into my overstimulated brain and that of other people with autism', says Jasmijn den Hoed. The Faculty of Social and Behavioural Sciences is exhibiting her artwork 'Overstimulated' in the restaurant near the blue wall during Autism Week 25 March…

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.

What impact does growing up in a musical environment or during the COVID-19 pandemic have on the brain development of teenagers? This was the focus of psychologist Lina van Drunen’s PhD research, which studied hundreds of twins. Her findings reveal that practising music slows brain development, presenting…

On June 10, Michelle Achterberg received the prize for best dissertation from the Dutch Neurofederation, the network of Dutch neuroscientists, for her thesis 'Like me, ore else...'. Achterberg obtained her doctorate cum laude from the Gravitation Program 'Samen Uniek' of the Leiden Consortium on Individual…

There is a reasonable chance that you came to this reading list through a social medium. Now it's our job to keep your attention. We are going to do our best. There are so many distractions; from notifications on your phone, to another screen near you, that may also be screaming for attention. Every…

Hoping to learn something about the human brain, Leiden researchers are creating a setup to shoot single photons, particles of light, into someone’s eye. ‘The eye is a passageway to the brain.’

Autism, Alzheimer’s, and bipolar disorder: can the development of these mental health conditions be influenced by the ketogenic diet? Increasingly, research suggests it might. 'For those it helps, it can be life-changing,' says neuroscientist Eline Dekeyster.

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…

BRAIN Biotech and the Leiden University will jointly develop an Aspergillus based production strain with high yield and thus contribute to a bio-based circular economy. The cooperation is based on BRAIN´s molecular tool BEC.

Deep-brain stimulation (DBS) is the most promising surgical treatment for movement and neuropsychiatric disorders, but is accompanied by unwanted side effects. Birte Forstmann, professor by special appointment, has been awarded a ERC Proof of Concept Grant to create an atlas of the human deep brain…

During ExpeditionNEXT in Middelburg, NeurolabNL youth, together with researchers from Leiden University and Erasmus University, handed over a unique research agenda to NWO Chairman Marcel Levi. In it, young people share what they would most like to learn about themselves and the brain.

‘We didn’t find any mechanisms in the brain for transmitting child abuse from generation to generation. What we did find is that experiences of neglect and abuse affect the brain differently,’ concludes Lisa van den Berg (Clinical Psychology). PhD defence 30 June.

PhD candidate Mengxu Zhang (Division of Systems Pharmacology and Pharmacy) published a comprehensive and important review on “The potential impact of CYP and UGT drug-metabolizing enzymes on brain target site drug exposure” in Drug Metabolism Reviews.

Part of our social contact is currently online, with no physical proximity. Does digitalisation mean that we are losing an effective way of making contact with one another? This is what Reinoud Kaldewaij will be studying with a Veni subsidy from the Dutch Research Council (NWO). 'An issue that will…

Hunter-gatherers acquire their food through complex gender-specific foraging techniques for a relatively stable and diverse supply of energy. New research indicates that this specialisation by boys and girls starts at a very young age. Most likely, this enabled the human species to evolve much larger…

Nanomaterials can pass much further along the food chain than was previously thought. The particles can change shape and size in each organism, enabling them to pass on to the next one in the chain. Researchers from the Institute of Environmental Sciences discovered this accidentally when using a novel…
