    Authors: Boswinkel, Vivian;

    This thesis gives insights into neonatal brain injury, brain growth and neurodevelopmental outcome in moderate-late preterm (MLPT) infants, born at 32–36 weeks’ gestation. Additionally, we describe the neurodevelopmental outcome of preterm infants with cerebellar hemorrhage (CBH). In Chapter 2 we give an overview of the literature regarding brain injury and development in MLPT infants. Most frequently studied types of brain injury were intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL). Incidences of other forms of brain injury were sparsely reported. In addition, there is a lack of knowledge regarding the effect of brain injury on neurodevelopmental outcome in MLPT infants. In Chapter 3, we investigate current practice regarding neurological surveillance in MLPT infants in the Netherlands and Canada. We found variations in local practices regarding e.g. admission criteria, neuroimaging and follow-up. This may partially be explained by the lack of guidelines regarding care of MLPT infants. The above indicates that considerable knowledge about MLPT infants is still lacking. By conducting a prospective cohort study, we sought to fill some of the gaps in knowledge. The BIMP-study (Brain Imaging in Moderate-late Preterm infants) was performed between 2017-2019 at the Isala Women and children’s Center in Zwolle, the Netherlands. MLPT infants underwent cranial ultrasound and MRI. In the BIMP-cohort (n= 166), a high incidence of mild brain lesions (71.7%) was found. Frequent findings were signs suggestive of white matter injury, and small hemorrhages, including CBH. Moderate-severe brain lesions were seen in 3.6% of infants. We compared linear measurements of brain structures between MLPT and full-term infants. Biparietal diameter and basal ganglia width were smaller in MLPT infants. We found no differences in linear measurements or in brain volumes between moderate preterm (MP, 32+0–33+6 weeks) and late preterm infants (LP, 34+0–35+6 weeks). Mild brain lesions had no effect on brain volumes (Chapters 4, 5 and 6). In Chapter 7, we present a preliminary overview of the follow-up of 85 MLPT infants who have now reached 24 months of age. Almost one in three (30.6%) had an suboptimal outcome score. Given the descriptive nature of this overview and the fact that follow-up is still ongoing, we could not yet draw any further conclusions. In Chapter 8, we explore the association between the size and location of CBH in preterm infants ≤34 weeks (n = 218) and neurological outcome around two years of age. All infants with massive CBH and involvement of the vermis on neonatal MRI had a less favorable outcome. Infants with limited CBH had a more favorable outcome than infants with massive CBH. Although much research is still needed to provide strict recommendations, we advise the following based on our findings and the current literature: - Standard neuroimaging in MLPT infants does not seem warranted at present. - Use a low threshold for accepting MLPT infants in neurodevelopmental follow-up programs and interventions as they are at risk of neurodevelopmental and behavioral problems. - Assess CBH based on size and location. With a special note on vermian involvement.

    Background: Current developments towards multipin, dry electrodes in electroencephalography (EEG) are promising for applications in non-laboratory environments. Dry electrodes do not require the application of conductive gel, which mostly confines the use of gel EEG systems to the laboratory environment. Aim: The aim of the current study is to validate soft, multipin, dry EEG electrodes by comparing their performance to conventional gel EEG electrodes. Methods: 15 healthy volunteers performed three tasks, with the 32-channel gel EEG system and the 32-channel dry EEG system: the 40Hz Auditory Steady-State Response (ASSR), the checkerboard paradigm, and the eyes open/closed task. Within-subject analyses were performed to compare the signal quality in time, frequency and spatial domain. Results: The results showed strong similarities between the two systems in time and frequency domain, by strong correlations of the visual (ρ=0.89) and auditory evoked potential (ρ=0.81), and moderate to strong correlations for the alpha band during eyes closure (ρ=0.81-0.86) and the 40Hz-ASSR power (ρ=0.66-0.72), respectively. However, delta and theta band power was significantly increased, and the signal-to-noise ratio was significantly decreased for the dry EEG system. Topographical distributions were comparable for both systems. Application time of the dry EEG system was significantly decreased with 8min. Conclusion: It can be concluded that the soft, multipin dry EEG system can be used brain activity research with similar accuracy as conventional gel electrodes.

    Authors: Aghajani, M.;

    The work presented in this thesis provides important new clues on the neurobiology of juvenile psychopathic traits in clinically antisocial juveniles. The data specifically shows that these traits are ostensibly underpinned by highly specific corticolimbic network dysfunctions, in which amygdala subregional networks seem particularly relevant. That data additionally suggests that some of these network dysfunctions and their associated neurocognitive deficits are possibly driven by alterations in the oxytocinergic system. Interestingly, the data also provides preliminary neurobiological support for the scientific utility of using juvenile psychopathic traits to subtype the highly heterogeneous group of clinically antisocial teens. While these data may represent important new steps towards a deeper understanding of clinical youth antisociality, their significance has to be evaluated by replication studies that further explore and validate the findings presented here.

    Reactive and proactive subtypes of aggression have been recognized to help parse etiological heterogeneity of this complex phenotype. With a heritability of about 50%, genetic factors play a role in the development of aggressive behavior. Imaging studies implicate brain structures related to social behavior in aggression etiology, most notably the amygdala and striatum. This study aimed to gain more insight into the pathways from genetic risk factors for aggression to aggression phenotypes. To this end, we conducted genome-wide gene-based cross-trait meta-analyses of aggression with the volumes of amygdala, nucleus accumbens and caudate nucleus to identify genes influencing both aggression and aggression-related brain volumes. We used data of large-scale genome-wide association studies (GWAS) of: (a) aggressive behavior in children and adolescents (EAGLE, N = 18,988); and (b) Magnetic Resonance Imaging (MRI)-based volume measures of aggression-relevant subcortical brain regions (ENIGMA2, N = 13,171). Second, the identified genes were further investigated in a sample of healthy adults (mean age (SD) = 25.28 (4.62) years; 43% male) who had genome-wide genotyping data and questionnaire data on aggression subtypes available (Brain Imaging Genetics, BIG, N = 501) to study their effect on reactive and proactive subtypes of aggression. Our meta-analysis identified two genes, MECOM and AVPR1A, significantly associated with both aggression risk and nucleus accumbens (MECOM) and amygdala (AVPR1A) brain volume. Subsequent in-depth analysis of these genes in healthy adults (BIG), including sex as an interaction term in the model, revealed no significant subtype-specific gene-wide associations. Using cross-trait meta-analysis of brain measures and psychiatric phenotypes, this study generated new hypotheses about specific links between genes, the brain and behavior. Results indicate that MECOM and AVPR1A may exert an effect on aggression through mechanisms involving nucleus accumbens and amygdala volumes, respectively.

    Authors: Sack, Alexander T.; Schuhmann, Teresa; de Graaf, Tom A.;

    Non-invasive brain stimulation (NIBS) techniques, including transcranial magnetic stimulation (TMS) and low-intensity transcranial electric current stimulation (tES), offer the unique possibility of directly interfering with local and remote neural network activity in conscious human participants, with a quantifiable impact on behaviour or cognition. This makes brain stimulation in many ways complementary to brain imaging and a combination of both techniques particularly desirable. Brain stimulation can be combined with brain imaging either in two separate experimental sessions or simultaneously by using TMS or tES inside the MR scanner. The simultaneous combination of NIBS with fMRI enables the modulation of brain circuits, while concurrently assessing direct and remote neural network effects across the entire brain and linking these (network) activity changes to the induced behavioural manipulation. This chapter introduces the fundamental workings of NIBS and its application in fundamental brain research, rehabilitation and psychiatry and describes the different possibilities of combining brain stimulation and brain imaging with a focus on the methodological and technical challenges. Concrete research studies are used to exemplify how valuable such combined brain stimulation and brain imaging studies can be for fundamental and clinical brain research.

    Schizophrenia is a devastating psychiatric illness with high heritability. Brain structure and function differ, on average, between schizophrenia cases and healthy individuals. As common genetic associations are emerging for both schizophrenia and brain imaging phenotypes, we can now use genome-wide data to investigate genetic overlap. Here we integrated results from common variant studies of schizophrenia (33,636 cases, 43,008 controls) and volumes of several (mainly subcortical) brain structures (11,840 subjects). We did not find evidence of genetic overlap between schizophrenia risk and subcortical volume measures either at the level of common variant genetic architecture or for single genetic markers. The current study provides proof-of-concept (albeit based on a limited set of structural brain measures), and defines a roadmap for future studies investigating the genetic covariance between structural/functional brain phenotypes and risk for psychiatric disorders.

    Authors: Bernas, Antoine;

    Neuropsychiatric disorders, such as autism, schizophrenia or epilepsy are neurological diseases that present psychiatric symptoms. Since these mental disorders are at the border between neurology and psychology, they are often ill-defined and the effects of treatment are not always successful. In this research new models were developed for extracting brain dynamics (also called neurodynamics) using functional magnetic resonance imaging (fMRI) from adolescents with autism and elderly with cognitive decline in epilepsy. The models were also applied to study the Mozart effect (cognitive and attention enhancement through intensive listening to Mozart’s music). The dynamics methods used come from different fields of research in dynamic systems, such as financial markets, geophysics and evolutionary game theory. This research shows that using these new image-based brain analysis techniques combined with modern classification (machine learning) algorithms, one can accurately and objectively diagnose autism, or provide informative neurodynamics features in case of cognitive decline in ageing. These results are promising for further developing computer-aided diagnostic tools and the investigation of targeted treatments for neuropsychiatric disorders.

    Background: Over the last decades many brain imaging studies have contributed to new insights in the pathogenesis of psychiatric disease. However, in spite of these developments, progress in the development of novel therapeutic drugs for prevalent psychiatric health conditions has been limited.Objective: In this review we discuss translational, diagnostic and methodological issues that have hampered drug development in CNS disorders with a particular focus on psychiatry. The role of preclinical models is critically reviewed and opportunities for brain imaging in early stages of drug development using PET and fMRI are discussed. The role of PET and fMRI in drug development is reviewed emphasizing the need to engage in collaborations between industry, academia and phase I units.Conclusion: Brain imaging technology has revolutionized the study of psychiatric illnesses and during the last decade neuroimaging has provided valuable insights at different levels of analysis and brain organization, such as effective connectivity (anatomical), functional connectivity patterns and neurochemical information that may support both preclinical and clinical drug development. Since there is no unifying pathophysiological theory of individual psychiatric syndromes and since many symptoms cut across diagnostic boundaries, a new theoretical framework has been proposed that may help in defining new targets for treatment and thus enhance drug development in CNS diseases. In addition, it is argued that new proposals for data-mining and mathematical modelling as well as freely available databanks for neural network and neurochemical models of rodents combined with revised psychiatric classification will lead to validated new targets for drug development.

    Authors: Boswinkel, Vivian;

    This thesis gives insights into neonatal brain injury, brain growth and neurodevelopmental outcome in moderate-late preterm (MLPT) infants, born at 32–36 weeks’ gestation. Additionally, we describe the neurodevelopmental outcome of preterm infants with cerebellar hemorrhage (CBH). In Chapter 2 we give an overview of the literature regarding brain injury and development in MLPT infants. Most frequently studied types of brain injury were intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL). Incidences of other forms of brain injury were sparsely reported. In addition, there is a lack of knowledge regarding the effect of brain injury on neurodevelopmental outcome in MLPT infants. In Chapter 3, we investigate current practice regarding neurological surveillance in MLPT infants in the Netherlands and Canada. We found variations in local practices regarding e.g. admission criteria, neuroimaging and follow-up. This may partially be explained by the lack of guidelines regarding care of MLPT infants. The above indicates that considerable knowledge about MLPT infants is still lacking. By conducting a prospective cohort study, we sought to fill some of the gaps in knowledge. The BIMP-study (Brain Imaging in Moderate-late Preterm infants) was performed between 2017-2019 at the Isala Women and children’s Center in Zwolle, the Netherlands. MLPT infants underwent cranial ultrasound and MRI. In the BIMP-cohort (n= 166), a high incidence of mild brain lesions (71.7%) was found. Frequent findings were signs suggestive of white matter injury, and small hemorrhages, including CBH. Moderate-severe brain lesions were seen in 3.6% of infants. We compared linear measurements of brain structures between MLPT and full-term infants. Biparietal diameter and basal ganglia width were smaller in MLPT infants. We found no differences in linear measurements or in brain volumes between moderate preterm (MP, 32+0–33+6 weeks) and late preterm infants (LP, 34+0–35+6 weeks). Mild brain lesions had no effect on brain volumes (Chapters 4, 5 and 6). In Chapter 7, we present a preliminary overview of the follow-up of 85 MLPT infants who have now reached 24 months of age. Almost one in three (30.6%) had an suboptimal outcome score. Given the descriptive nature of this overview and the fact that follow-up is still ongoing, we could not yet draw any further conclusions. In Chapter 8, we explore the association between the size and location of CBH in preterm infants ≤34 weeks (n = 218) and neurological outcome around two years of age. All infants with massive CBH and involvement of the vermis on neonatal MRI had a less favorable outcome. Infants with limited CBH had a more favorable outcome than infants with massive CBH. Although much research is still needed to provide strict recommendations, we advise the following based on our findings and the current literature: - Standard neuroimaging in MLPT infants does not seem warranted at present. - Use a low threshold for accepting MLPT infants in neurodevelopmental follow-up programs and interventions as they are at risk of neurodevelopmental and behavioral problems. - Assess CBH based on size and location. With a special note on vermian involvement.

    Background: Current developments towards multipin, dry electrodes in electroencephalography (EEG) are promising for applications in non-laboratory environments. Dry electrodes do not require the application of conductive gel, which mostly confines the use of gel EEG systems to the laboratory environment. Aim: The aim of the current study is to validate soft, multipin, dry EEG electrodes by comparing their performance to conventional gel EEG electrodes. Methods: 15 healthy volunteers performed three tasks, with the 32-channel gel EEG system and the 32-channel dry EEG system: the 40Hz Auditory Steady-State Response (ASSR), the checkerboard paradigm, and the eyes open/closed task. Within-subject analyses were performed to compare the signal quality in time, frequency and spatial domain. Results: The results showed strong similarities between the two systems in time and frequency domain, by strong correlations of the visual (ρ=0.89) and auditory evoked potential (ρ=0.81), and moderate to strong correlations for the alpha band during eyes closure (ρ=0.81-0.86) and the 40Hz-ASSR power (ρ=0.66-0.72), respectively. However, delta and theta band power was significantly increased, and the signal-to-noise ratio was significantly decreased for the dry EEG system. Topographical distributions were comparable for both systems. Application time of the dry EEG system was significantly decreased with 8min. Conclusion: It can be concluded that the soft, multipin dry EEG system can be used brain activity research with similar accuracy as conventional gel electrodes.

    Authors: Aghajani, M.;

    The work presented in this thesis provides important new clues on the neurobiology of juvenile psychopathic traits in clinically antisocial juveniles. The data specifically shows that these traits are ostensibly underpinned by highly specific corticolimbic network dysfunctions, in which amygdala subregional networks seem particularly relevant. That data additionally suggests that some of these network dysfunctions and their associated neurocognitive deficits are possibly driven by alterations in the oxytocinergic system. Interestingly, the data also provides preliminary neurobiological support for the scientific utility of using juvenile psychopathic traits to subtype the highly heterogeneous group of clinically antisocial teens. While these data may represent important new steps towards a deeper understanding of clinical youth antisociality, their significance has to be evaluated by replication studies that further explore and validate the findings presented here.
