Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

The work presented in this thesis addresses the role of the locus coeruleus (LC) - norepinephrine (NE) system in various aspects of human cognition, and the modulation of brain state.

There is a link in adolescents between brain connections and impulsiveness. Leiden researchers have discovered that these connections also predict which adolescents will make more impulsive choices two years further on.

How is structural and functional brain development related to behavioral change in cognitive-control, impulse regulation, and socio-emotional functioning?

Nowadays children grow up with social media. This may influence the development of brain regions involved in social interaction. In their review article in Nature Communications, Crone and Konijn illustrate how neuroscience can contribute to a better understanding of how media and peers influence adolescents'…

An Integrative Approach to the Hominin Record

This interdisciplinary minor emphasizes the diversity and complementarity of various cognitive neuroscience approaches to understanding the human brain.

This minor focuses on the cognitive processes that influence the interaction between the brain and the mind.

The Brain and Education lab is a research group in the Institute of Education and Child Studies at Leiden University in the Netherlands. We use a Developmental Cognitive Neuroscience approach to study the development of complex cognitive processes involved in learning and academic skills such as reading…

Neuroimaging research has greatly advanced our insights on how the brain is organized. Now is the time for the next step: Imagine what would be possible when we cannot only map brain-functioning, but use neuroimaging to voluntarily regulate brain-activity!

Fundamental insights into the working of the adolescent brain help lecturers and parents to teach adolescents to function better. Professor Eveline Crone studies executive functions – such as planning and behaviour – in the adolescent brain.

Your brain responds in a predictable way when it encounters new or difficult tasks. This unique book teaches you concrete techniques rooted in cognitive science that will improve the way you learn and think about code.

Researchers have been working for centuries in mapping the human brain. But in the year 2017 some brain structures remain still not well mapped, especially those located at the brainstem. In this paper, we quantified the test–retest reliability of imaging the brainstem nucleus locus coeruleus in vivo…

The more opportunities a child has to learn and develop, the stronger his or her future position in society. Leiden University investigates how the brain picks up information, and how learning processes can be influenced positively.

The factors that dynamically sculpt the inter-regional correlation of brain patterns are poorly understood. Here, we test the hypothesis that they are shaped by the catecholaminergic neuromodulators norepinephrine and dopamine.

The LIBC is actively involved in training and education in the field of brain and cognition.

This study is the first to directly relate brain development to sex differences and school performance. The results debunk the myth that brain development is slower in boys.

What role do parent-child interactions play in the development, maintenance and treatment of depression in young people?

What is the neural basis of social decision-making across childhood, adolescence and adulthood and what are the developmental patterns in terms of behavior and brain activation?

This project looks at how the native language influences processing mechanisms of non-native language(s) as well has how it influences brain structure and functional connectivity.

Multiple Sclerosis, Parkinson’s and Alzheimer’s disease are the most common neurodegenerative disorders. Unfortunately, no effective treatments are currently available to halt the progression of these neuroinflammatory diseases [1].

Smartphone behaviors are so common but how does the brain generate this behavior? The Cognition in the digital environment laboratory (CODELAB) investigated the brain activity surrounding smartphone interactions with the help of Artificial Intelligence. According to their research, the brain fluidly…

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

Using brain imaging to discover the area in the brain that recognizes emotion.

This project investigates properties of quantity expressions across languages from the perspective of how quantity is represented in the human brain.

Cardiovascular diseases are a leading cause of death worldwide, and better models are urgently needed for disease progression studies and drug development.

A P300-based Brain Computer Interface character speller, also known as P300 speller, has been an important communication pathway, under extensive research, for people who lose motor ability, such as patients with Amyotrophic Lateral Sclerosis or spinal-cord injury because a P300 speller allows human-beings…

Advanced UHF MRI techniques provide powerful tools for studying the zebrafish brain, an emerging model in neurological research. In this work, various MRI and localized MRS methods are optimized and employed for UHF strength for studying the zebrafish brain.

When we are around four years old we suddenly start to understand that other people think and that their view of the world is often different from our own. Researchers in Leiden and Leipzig have explored how that works. Publication in Nature Communications on 21 March.

A key challenge in neuroscience is understanding how neurons in hundreds of interconnected brain regions integrate sensory inputs with previous expectations to initiate movements and make decisions.

Serge Rombouts is a physicist whose PhD thesis was about functional MRI (fMRI). This visualises activity in regions of the brain. The appealing images of glowing brain regions that emerge from the computer are the result of calculations. According to Rombouts, this isn’t proper artificial intelligence.…

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

Brain activity changes as people age, which can lead to cognitive decline. By measuring and comparing brain data from mice and humans, the researcher will investigate how the brain’s noise levels change with age and affect choice behavior.

Diacylglycerol lipases (DAGLα and DAGLβ) convert diacylglycerol to the endocannabinoid 2-arachidonoylglycerol. Our understanding of DAGL function has been hindered by a lack of chemical probes that can perturb these enzymes in vivo.

Are disturbances to the brain, such as Alzheimer's or autism, linked to specific defects in the underlying communication networks in the brain? If this is the case, subtle changes in the networks can act as a marker for brain disturbances. Neuroscientist Serge Rombouts will be investigating this, together…

Children and adolescents really do use their ‘smart’ brain areas. This has been confirmed by an extensive and long-running study of the brain carried out by developmental psychologist Sabine Peters . Her findings can have important consequences for education. PhD defence 27 January.

During adolescence, mood disorder onset peaks. Mood variability is associated with negative mental health outcomes, so understanding biological factors that might be associated with mood variability, such as sleep and structural brain development, could elucidate the mechanisms underlying mood and anxiety…

Brain development in children with an extra X chromosome as compared to children with autism: evidence from MRI

A tried and tested medication for treating ADHD works differently than expected in the brains of healthy individuals during rest: rather than stimulating brain activity, it suppresses it.

Our childhood years largely determine how we will fare later in life. In the first two decades of our life, our brain is still developing, which is clearly reflected in our behaviour. By studying how the young brain develops and how children behave, researchers can learn important information about…
