FinnBrain Research consists of many work packages that cover for example structural and functional brain measurements, neuropsychological functioning, parent-child interaction, molecular genetics, gut microbiota, HPA axis functioning, and pediatric outcomes.
Child Development and Parental Functioning Lab
The aim of this project is to create a more complete understanding about the role of environment and biological processes in child self-regulation development and subsequently, about the earliest origins of psychopathology in childhood. More specifically, the aim is to study the early development of emotional and cognitive self-regulation including attention, temperamental traits and executive functioning especially in the context of early life stress exposure. The different factors of the self-regulation capacity will be studied in relation to later child socio-emotional and cognitive development and psychopathology. The project collaborates closely with the FinnBrain Neuroimaging lab, and in addition to brain imaging data, the behavioral data is combined with several biological and genetic indicators derived from e.g. gut microbiota, blood, hair and saliva samples collected in other labs.
We also investigate the development of child stress regulation at home and in out-of-home childcare. We are interested in child individual characteristics and environmental factors that are associated with child well-being.
In addition, we study the possible moderating role of parenting in the development of child self-regulation. More specifically, the effects of parents’ psychological well-being, cognition, attention, and executive functions and maternal caregiving behavior on the different patterns of children’s self-regulation are studied.
This study provides new knowledge about the mechanisms between child regulation capacity and brain development, which will help to develop evidence-based and targeted treatment and preventative interventions for small children and their families.
Child development and parenting are studied in a longitudinal design from pregnancy until school age (Figure 1.)
The study includes several PhD and Post-Doc studies.

The aim of the COVID-19 substudy is to investigate the psychological well-being and symptoms of the parents, children and families participating in the FinnBrain Study during the COVID-19 pandemic. Additionally, we explore the longitudinal stress hormone levels from hair samples and whether the stress hormone concentrations are associated with short and long-term psychological distress. We also investigate the change in vaccine attitudes during the pandemic (see also the description on the vaccine attitudes substudy).
The uniqueness of the substudy lies in the broad background data gathered from the FinnBrain Study families – parents and children. The data collected during pandemic can be linked with this data to better understand longitudinal influences of the pandemic on the families as well as the ways to support families during this exceptional period.

Dental Fear, Oral Health-Related Behaviours and Quality of Life
We are interested on the interplay of family-, child-, environment and oral health-related factors in the development of dental fear among children. Especially we are interested whether the development of dental fear is more strongly related to psychosocial factors within the family or with the use of oral health care services and oral health-related quality of life.
We also study how the behavior, attitudes and knowledge of children and adolescents and changes in these are related to the behavior, attitudes and knowledge and psychosocial factors of their parents and oral health-related quality of life of both children and their parents.

Gut-Brain Axis Lab
FinnBrain Birth Cohort Study focuses on the role of prenatal and early life environment and stress exposures on child development. Previous literature suggests that gut microbiota (GM) harbors a bidirectional communication with central nervous system, metabolic pathways and immune and stress regulatory systems. Recently, the role of GM in shaping human brain development has gained increasing interest. In the FinnBrain Gut-Brain Axis Lab we use repeated fecal samples and precise phenotyping to assess if and how prenatal and early life exposures are reflected to infant GM. Further, we the alterations in GM are associated with brain developmental (e.g. neuropsychological profiles, behavioral phenotypes) trajectories and later health outcomes.
Early nutrition and breastfeeding has important effect on infant gut microbiota. We have repeated breast milk sampling from 2-3 mo, 6 mo, 12-14 mo, 18 mo and 24 mo postpartum. We aim to study how maternal health is associated with breast milk composition, and further, how breast milk composition relates to child gut microbiota composition and child health and development.
We have successfully collected and analyzed fecal samples with 16S RNA sequencing (Illumina MiSeq) at several time points between 2.5 months and 5 years of child age, each time point consisting of around 150-500 infants. Additional to next-generation sequencing, we are performing metabolomic analyses of the fecal samples. We have access to other biological samples (including saliva cortisol, hair cortisol concentration, breast milk, urine as well as blood samples), extensive neuropsychological phenotyping (see Child Development and Parental Functioning Lab) and neuroimaging data (see Neuroimaging Lab) from the subjects.
This enables us in FinnBrain Gut-Brain Axis Lab to investigate how prenatal and early life stress and other exposures are reflected to the GM composition and functioning, and how these are associated with mother and child stress regulation and neuropsychological outcomes as well as development of chronic conditions.

HPA Axis Functioning and Development Lab
Hypothalamic-pituitary-adrenal axis (HPA axis) is one of the main stress regulation systems. The aim of the HPA axis Functioning and Development Lab is to study longitudinally several aspects of HPA axis functioning and its development from pregnancy to early childhood in different environmental contexts in order to gain better understanding of the role of stress regulation in child development and health especially during the first years of life. Our three main projects focus on:
1) The association between the prenatal maternal psychological distress exposure and the infant acute cortisol stress response at child ages of 2.5, 6 and 14 months.
2) The role of different childcare contexts and child individual characteristics on the child diurnal cortisol profiles at the age of 2, 3.5 and 5 years.
3) Associations of parental and child hair cortisol concentrations with a range of health and developmental outcomes during pregnancy and 1, 2.5 and 5 years postnatally.
Dysfunction of the HPA axis is linked with many diseases and it regulates and interacts with all main homeostatic and life supporting systems including metabolic, cardiovascular, immune, reproductive, and central nervous systems. The relevance of HPA axis functioning to the well-being and morbidity is studied widely but still less is known about the longitudinal development of the HPA-axis functioning during the early childhood in different contexts from pregnancy onwards. Better understanding of the functioning and the development of the child stress regulation system and its relevance to other homeostatic systems in the body and neuropsychological development is needed to find biomarkers and develop prevention to stress related illnesses.

Molecular Genetic Lab
The aim of the molecular genetic study is to clarify the role of genetic mechanisms in early development and prospectively in health. As genetic mechanisms, we will study epigenome, gene expression, and genetic variants (correlations, interactions and direct genetic effects).
The major research tracks are as follows:
1) We will examine the direct genetic effects on development and prospective health by analysis of the child’s genomic variations by GWAS and hypothesis-based analyses. (Study on direct genetic effects)
2) We will study the effect of interaction of genotype variations in the newborn with environment on development of the child. The environment include psychological and somatic factors related to the parents (sleep, life habits, attachment, psychological health incl. mood, anxiety, reactivity stress and later; obesity, smoking and use of alcohol, drugs and medication during pregnancy), as well as other factors such as delivery, complications in pregnancy, family environment, and infections. (Study on genetic interactions)
3) We will examine the effect of environment on epigenetic programming, gene expression and telomere length and contributing genetic factors. (Study on epigenome)
4) We will study the effect of parental genotypes on the growth environment, development of the child and prospective health. In addition, the direct genetic effects and genetic interactions among the parents will be examined. (Study on genetic correlations)

We study how early life exposures, genes and environment shape the brain structure and function. We are interested in how these, often subtle individual differences explain later characteristics, skills and health of the children.
Key facts on the data
• Infant MRI: ca. 180 newborns (2-5-week-olds) with structural MRI and additional 26 infants with fMRI, including resting state and social touch task fMRI.
• Infant EEG: paradigms measuring cerebral reactions to emotionally-valenced sounds have been acquired from approximately 180 newborns (1-3 days olds).
• Infant NIRS: We measured the functional brain responses to emotional sound and social touch in ca. 40 2-month-olds with near-infrared spectroscopy (NIRS).
• 2-year-old NIRS: We measured the functional brain responses to social touch in ca. 20 participants.
• 3-year-old EEG: we have repeated the infant paradigm and measured ca. 80 3-year-olds.
• We are currently collecting MR imaging data in 5-year-old children (target ca. 200 measurements). The imaging data will be coupled with performance in detailed neuropsychological assessments performed prior to imaging visits.

Childhood chronic diseases, such as atopic disorders (asthma and rhinitis), recurrent infections, obesity/overweight and sensations of pain, are an increasing health problem in western world. Today, 10-15% of small children are overweight, and 30% suffer from different pain or atopic disorders. According to prognoses, the incidence of childhood chronic disorders will increase.
FinnBrain Pediatrics is the pediatric lab of the FinnBrain Birth Cohort Study The aim is to provide information on the trajectories to childhood chronic disorders after prenatal and early postnatal exposures, such as maternal psychological distress. FinnBrain Pediatrics focuses on 1) the trajectories to chronic disorders up to 5 years, and 2) establishing the data collection sweep at the child age of 5 years during 2018-2021 (n=1200 children), including pediatric background history, blood tests, room dust samples to study the role of early-life indoor microbial exposure, and fecal samples to study the role of gut microbiota in the development of chronic disorders. The results may provide implications into the underlying mechanisms of childhood chronic disorders, and thus potentially contribute to prevention.

In Perinatal Health Work Package we are also researching alexithymia.
Alexithymia stands literally for “no words for feelings” and the term is used to describe personality traits characterized by difficulty in identifying and expressing feelings, externally-oriented thinking, and often scarce imagination. Alexithymia was first described in the 1970s in patients with psychosomatic symptoms. Indeed, its wide-ranging associations with, not only mental disorders, but also somatic symptoms and illnesses, has made alexithymia an interesting research subject. However, alexithymia itself is a trait, not a mental or personality disorder.
Our research group aims to improve the understanding of alexithymia, its nature and associations. Although alexithymia is typically associated with lack of emotional expression, alexithymia is not just this. The different dimensions of alexithymia are emphasized in different ways in people, and they also appear to differ, for example, in their links with mental health disorders and symptoms. Certain characteristics may even protect against some symptoms. One of our priorities is to further elucidate these mechanisms and associations. We are also interested in the relationship between alexithymia and lifestyle habits and behavioral addictions. The research on the inheritance of alexithymia and its significance in the growth environment in early childhood has so far been very limited, so we expect to gain completely new and interesting information on, for example, the relationship between parental alexithymia and the child’s growth and development.
Parental alexithymia was assessed with the 20-item Toronto Alexithymia Scale (TAS-20) 6 months after the child’s birth. In the future, we plan to assess the children’s alexithymic features using the Alexithymia Questionnaire for Children, which is a child-friendly version of the TAS-20.

Population Based Registries
This multidisciplinary project (combining expertise from the social and medical sciences) asks what effects do dimensions of parents’ socioeconomic (e.g. occupational and educational) and family demographic life histories prior to offspring birth have on their children’s health, well-being and development, from early life and beyond. The early years, including the prenatal period, are important for healthy psychological and physical development, and have implications for educational achievement, labor market success, and later-life health and overall well-being. The conditions promoting early life are unevenly distributed between children and their families, therefore implying social inequalities in children’s lives already from the very beginning. This project presents a new longitudinal perspective on the formation of child health, well-being and development during pregnancy and the first year of life by focusing on the effects of the parents’ socioeconomic and demographic life course trajectories from childhood onwards. It offers possibilities for improved understanding of the factors that affect children’s healthy development, the social inequalities in these conditions, and the policy interventions that can be used to promote favorable outcomes. To achieve this, we combine data from the FinnBrain cohort study with population register data to form a unique dataset of parents’ life course trajectories, and parents’ and children’s health.

Speech and Language Lab
A fundamental question in research on language development asks what type of neurocognitive learning mechanisms allow children to learn language based on hearing language in daily social interactions. Although typically this process unfolds apparently effortlessly, children exhibit individual differences in the rate of their development. In the Speech and Language Lab, we are explaining what underlies these individual differences. We use that information to better understand the ways in which neurocognitive mechanisms and social interactions support children’s speech and language development.
In close collaboration with the other FinnBrain Labs and affiliates, we are currently examining e.g. potential effects of early mother-child communication, maternal mental health, child temperament and attentive skills, genetic risk and brain development on speech and acquisition. Our ultimate goal is to build a comprehensive multifactorial of model of risk and protective factors of children’s language development. In addition answering theoretical questions, this model will be useful for identification and treatment of speech and language disorders in children.

Maternal stress during pregnancy has been identified as one of the relevant exposures for later offspring health and development. Yet, the underlying mechanisms bridging the exposures with later outcomes remain to be studied and especially measures of direct fetal exposure are lacking. FinnBrain Tooth Fairy -project will fill this gap by examining deciduous (baby) teeth as a potential biomarker for fetal stress exposure. Deciduous teeth start developing from the 14th week of pregnancy onwards and embed signatures of immune system functioning, stress, and chemical exposure. They offer retrospective temporal dissection of fetal and infant chemical milieu of environmental exposure to toxins and endogenous responses to stressors. We aim to investigate how this early milieu is associated with later development, including brain and behavioral development. Professor Manish Arora is the key collaborator in this project (New York, Icahn School of Medicine at Mount Sinai).
Next to clean water and nutrition, vaccination is widely regarded as one of the most important public health achievements. According to the Finnish Institute for Health and Welfare (www.thl.fi) most parents allow their children to get vaccinated with the vaccines included in the national immunization programme. Previous studies, however, show that people may feel hesitant towards vaccines despite choosing to get vaccinated. How strong the hesitancy is and what the reasons behind the hesitancy are, vary between individuals. Examples of factors behind vaccine hesitancy are a worry about the safety and efficacy of vaccines and a low trust in health authorities that offer and recommend vaccines.
The aim of this subproject that started in 2018, is to investigate to which degree vaccine hesitancy exists in Finland and to study possible reasons behind negative attitudes to vaccines. Parents of small children are an important group when it comes to investigating vaccine attitudes, because their children have the possibility to receive vaccines against several diseases. Better knowledge about the factors that affect the parents’ vaccine attitudes help developing the communication about vaccines between healthcare professionals and patients. Parents in the FinnBrain study answered a longer questionnaire about vaccine attitudes in 2018 and a shorter one during early summer, in 2020.

More information about the research group:
Sleep disturbances and sleep disorders are common across early childhood, and they may influence the well-being of all family members. In adulthood, insomnia is the most typical sleep disorders, while problems in diurnal rhythm and bedtime habits are more common issues in children. Importantly, both child and adult sleep disturbances can often be effectively treated, although much more information is needed on factors influencing the development of sleep patterns. Moreover, the role of sleep patterns in shaping child neuropsychological development is an important research topic. FinnBrain sleep studies cover both children and adults and target the frequency and stability of sleep disturbances as well as the profiles of typical sleep patterns across childhood development and during pregnancy. One of the special foci is to study how sleep patterns and disturbances influences child development and health. These data will help in the development of targeted treatments for sleep disturbances. The work in FinnBrain is done in close collaboration with the Child Sleep Study (National Institute for Health and Welfare, University of Helsinki, University of Tampere).
