Bodily sensations are one of the major building blocks of emotional experience. However, people differ in their ability to recognise and name their emotions, especially those in response to complex phenomena such as climate change or the COVID-19 pandemic. Therefore, we investigated whether the bodily sensation maps (BSMs) approach can be employed...

In recent years the association between video games, cognition, and the brain has been actively investigated. However, it is still unclear how individual predispositions, such as brain structure characteristics, play a role in the process of acquiring new skills, such as video games. The aim of this preliminary study was to investigate whether acqu...

Being a late talker constitutes a risk factor for later neurodevelopmental disorders; however, its neurobiological basis remains unexplored. We aimed to determine the unique and mutual correlates of late talking and developmental dyslexia on brain structure and behavioral outcomes in a large sample of 8- to 10-year-old children in a between-groups...
Article
Full-text available
A growing body of empirical evidence supports the notion of diverse neurobiological processes underlying learning-induced plasticity changes in the human brain. There are still open questions about how brain plasticity depends on cognitive task complexity, how it supports interactions between brain systems and with what temporal and spatial traject...

The neural plasticity underlying language learning is a process rather than a single event. However, the dynamics of training-induced brain reorganization have rarely been examined, especially using a multimodal magnetic resonance imaging approach, which allows us to study the relationship between functional and structural changes. We focus on sign...
Article
There is strong evidence that neuronal bases for language processing are remarkably similar for sign and spoken languages. However, as meanings and linguistic structures of sign languages are coded in movement and space and decoded through vision, differences are also present, predominantly in occipitotemporal and parietal areas, such as superior p...

Despite dissimilarities among scripts, a universal hallmark of literacy in skilled readers is the convergent brain activity for print and speech. Little is known, however, whether this differs as a function of grapheme to phoneme transparency in beginning readers. Here we compare speech and orthographic processing circuits in two contrasting langua...

Several etiological theories, in particular neuronal noise and impaired auditory sampling, predicted neurotransmission deficits in dyslexia. Neurometabolites also affect white matter microstructure, where abnormalities were previously reported in dyslexia. However findings from only few magnetic resonance spectroscopy studies using diverse age grou...
Article
Objective: Decreased activation to print in the left ventral, dorsal, and anterior pathways has been implicated in readers with dyslexia (DRs) but also is characteristic for typical beginning readers. Because most studies have compared DRs with their age-matched peers, the observed results could represent a dyslexia phenotype or a developmental de...

This is a 24-month longitudinal study focused on asymptomatic subjects with incidental MRI brain findings suggestive of multiple sclerosis (termed radiologically isolated syndrome, RIS) who will be compared with healthy controls and clinically definite multiple sclerosis patients. The aim of the study is to examine RIS subjects using cognitive testing and non-conventional magnetic resonance to identify patterns of hidden damage to the nervous system despite the absence of symptoms. We are now recruiting a post-doc with neuroimaging/data science skills to this study (four-year contract starts 1st Oct 2022, based in Nencki Institute, Warsaw).

Project
The aim of our research project is to understand and describe how climate change makes us feel and what it means for our mental health and climate action taking. To this end, we will conduct a series of studies using questionnaire and experimental methods. The research will be based on data collected in Poland and Norway, two countries heavily dependent on fossil fuels, but with a different social and individual perception regarding the urgency of climate action. https://climate-change-emotions.org/
Project
Learning new skills is essential for being able to meet the challenges of everyday life. We learn to use of new hardware, software, playing musical instruments or speaking a second language. Without learning new skills we would not be able to stay up to date in an ever-changing world. However the learning process might be different depending on the type of skill we want to acquire. At the same time all changes in human behavior are reflected in the brain. These changes on the brain level are called neuroplasticity, that is the ability of the brain to undergo reorganization. In the last two decades the predominant view that neuroplasticity takes place early in life and becomes largely reduced in adulthood has been challenged. Contemporary research provided evidence for experience and practice-dependent neuroplasticity also in the adult human brain. Yet a lot remains to be discovered about how the adult brain changes in response to learning. When can we observe changes in brain function and structure while acquiring new skills? Are they irreversible or do they fade away when we do not use these skills? Is the time course of neuroplasticity similar for learning different skills? For complex skill learning do changes first occur at the level of sensorimotor cortex and later in more advanced higher order brain regions? What are the neuronal predispositions for learning a specific skill? The main aim of the current research project is uncovering the dynamics of adult human brain neuroplasticity in response to learning new skills. We have recently shown that the first 3 months of second language or script learning are critical for functional neuroplasticity. On the other hand, studies on instrumental musical training suggest neuroplastic changes after only few weeks of training. To reveal detailed time-course of brain reorganization we will examine two groups of subjects, where one will learn tactile Braille reading and the other to play piano/keyboard. These two types of skills require multisensory training, involving the components of sensorimotor systems together with higher-order cognitive processes. The trainings will last for 6 months with 90-minutes classes twice a week. During this time using non-invasive neuroimaging methods we will capture with unprecedented detail the functional and structural neuroplastic changes in the brain in response to learning. Subjects will participate in 6 neuroimaging sessions: before training, after 1 week, 6 weeks, 3 moths, 6 months and 12 months (i.e. 6 months after finishing the training). During functional brain imaging participants will perform tasks related to different aspects of tactile Braille reading or keyboard playing. We will also invite skilled Braille readers and professional piano players to perform these tasks in the MR scanner. This will allow us to directly compare if brain activation to new skill in late learners is becoming more similar to the one of experts in the course of learning. The current project will shed light on the understanding of the dynamics of functional and structural training induced neuroplasticity. Due to the longitudinal design of the project we will also have the opportunity to reveal what are the neuronal predispositions for learning new multisensory skills.
