Beschreibung: Multivariate EEG analyses are becoming increasingly popular in neuroscience and clinical applications due to their ability to capture the spatiotemporal dynamics of brain activity more comprehensively than univariate methods. While traditional EEG analyses (e.g., time-frequency analyses) focus on isolated electrodes or limited features, multivariate approaches leverage correlations, network dynamics, and high-dimensional data to uncover more nuanced insights.

Beschreibung: Theta oscillations (4 - 8 Hz) are present in the cortex and subcortically mainly in the hippocampus. Therefore, it is not surprising that they have been linked to various processes surrounding learning and memory. In working memory (WM) research, theta oscillations play a crucial role in WM retention. Here, they facilitate the encoding and maintenance of information during WM tasks. Theta oscillations are thought to synchronize neural networks involved in memory processes, promoting the coordination of neuronal firing patterns necessary for the retention of relevant information. Additionally, theta oscillations are associated with the integration of sensory information and the coordination of cognitive processes, contributing to the efficient functioning of working memory systems. The aim of this Bachelor's thesis is to review the current state of evidence on the role of theta oscillations during the retention phase of working memory tasks and to evaluate the proposed functional mechanisms underlying theta-mediated memory maintenance.

Beschreibung: This topic is concerned with one of the fundamental anatomical organizations of the visual system- the topographic organization of the retina corresponding to the topographic organization of the external world. It is the latter we deal with when interacting with the environment, and one of the most fundamental psychological constructs relating or linked to retinotopic organization is spatial attention. Picture yourself in a driving situation when you need to overtly attend to the road straight ahead, yet keep track of the sides in case a surprising event crosses the road that requires a behaviorally goal-directed reaction. Research has demonstrated that in this case we rely on the concept we call covert attention. The discovery of the retinotopic organization of the visual system is almost half a century old, with the emergence of neuroimaging technology in the 90s opening the view of its functional architecture measured non-invasively (fMRI) in the human brain. Consequently, non-invasive electro- and magnetophysiology research reports not only its topographic organization but also its functional dynamics on a millisecond scale. Recent considerations foreground the involvement of eye movements as an integral part of vision and the important dissociation between foveal and peripheral vision. Both eye movements and peripheral vision are as of yet rarely integrated in the conceptualization, study, and interpretation of retinotopic organization and the manifestation of spatial attention. The goal in this thesis project is to review, structure, and document the state-of-the-art of retinotopic mapping, the consideration of the oculomotor system or the lack thereof, and provide a summary of different approaches in terms of the dependent variables used to analyze and document retinotopic organization. Specifically, it is structured in three main parts: the first one is an overview of the basic layout of the visual system from retina to cortex and a review of the hemodynamic literature documenting retinotopic maps to date. The second part reviews and documents the existing non-invasive electro- and magnetophysiological literature attempting to establish the temporal dynamics of these maps, the relevant dependent metrics used, and their relationship to the hemodynamic literature. The third part evaluates and synthesizes the type and consequences of different eye movements regulating the image on the retina, the differentiation of foveal and peripheral vision, and their integration into the current state of the art in retinotopic maps. Finally, the goal is to summarize and synthesize whether and how the oculomotor system is considered in the analysis and interpretation of the retinotopic organization of the visual system and putatively identify future fruitful research directions.

Beschreibung: Depressive disorder (DD) represents a significant public health concern, as it affects millions of people and is the leading cause of disability globally. It most often occurs in adolescence, during which various physiological, psychological, and social changes heighten vulnerability. DD during adolescence is particularly troubling due to its impact on developmental milestones, academic performance, and social relationships. The disorder exhibits a notable heterogeneity, characterized by varying symptoms, severity, and outcomes across individuals, which complicates treatment efforts and prevention of relapses. Traditional treatment methods, while effective for some, do not cater to the individualized nature of psychiatric disorders, underscoring the urgent need for novel measurements and therapies that can address this variability. One such novel measurement are specific biomarkers, e.g. Frontal Alpha Asymmetry (FAA) as a basis for tailored treatment approaches in DD. However, there are inconsistencies in the research on FAA and DD. Numerous studies struggled to replicate the original findings and discrepancies in methodological approaches, as well as uncontrolled confounding factors such as age, gender and education further cloud the association between FAA and DD.

Beschreibung: In neuroscience, it is generally assumed that brain rhythms reflect the neural processes required to perform the cognitive operations demanded by the experiment task. This assumption has led to various theories regarding the role of gamma oscillations, proposing fundamental functions such as information binding or higher-order cognitive functions like memory and attention, among others. However, it remains unclear as to why gamma activity variation in the visual cortex primarily depends on stimuli properties such as the contrast and spatial frequency of grating stimuli. It has been reported that perception of gratings with high spatial frequency entails eye movements across the contrast border. Given that the brain continuously monitors oculomotor action, it may be crucial to consider these eye movements when investigating gamma oscillations. Literature Ray, S., & Maunsell, J. H. R. (2015).

Beschreibung: Alzheimer's disease (AD) is the most common form of dementia nowadays and poses a number of challenges due to its complex and heterogeneous nature. While advances in machine learning offer promising prospects for understanding the disease complexities and its evolution, conventional methods often overlook neuroanatomical heterogeneity between individuals, relying on case-control analyses. This thesis explores the promise of normative modeling in comparison with conventional methods for understanding disease and capturing the individual variability inherent in neurodegenerative diseases, with the aim of improving the accuracy of diagnosis and enhancing our understanding of the disease process.

Beschreibung: Background Traditional diagnostic approaches in psychology (e.g., ICD-11 and DSM-V) often categorize disorders as isolated, independent constructs. While these systems have been instrumental in standardizing diagnoses, they face several limitations. Issues such as comorbidity, symptom heterogeneity within disorders, and the inability to account for overlapping features challenge the validity of categorical diagnostic systems. In contrast, dimensional or transdiagnostic approaches offer a more integrative perspective by identifying shared features across disorders. These models seek to move beyond categorical boundaries, creating frameworks that better explain mental health phenomena and their underlying mechanisms. Prominent approaches include the Research Domain Criteria (RDoC), Hierarchical Taxonomy of Psychopathology (HiTOP), and network models. Objectives This bachelor's thesis aims to provide comprehensive literature research of dimensional models of psychopathology and explore their relevance to neuroscience. The project will focus on several key objectives: - Detailed overview of the dimensional models (structure, theoretical basis, development methods, relevance) - Outline of evidence (empirical research validating the models) in support of the models, as well as their advantages over traditional systems; address limitations - Recapitulation of the application of the models (e.g. in research, clinical integration, etc.) - In-depth review of their relevance and application in neuroscience, e.g., studies linking dimensional constructs to brain imaging, genetics, cognitive neuroscience Formalities This Bachelor's thesis must be written in English - strong English language skills are a prerequisite. The project is designed to be completed within one semester.

Beschreibung: Many neurodevelopmental conditions, such as autism and ADHD, are more commonly diagnosed in males than in females. This disparity may, in part, result from diagnostic criteria that are biased toward male presentations, leading to the underdiagnosis or misdiagnosis of females. At the same time there are neurobiological differences between males and females that may also contribute to such difference. The thesis should provide an overview of sex differences in the diagnosis, presentation and neurobiology of neurodevelopmental conditions and discuss the implications for clinical and research practice.

Beschreibung: Alzheimer's disease (AD) is a neurocognitive disorder that results in cognitive impairment. Onset of AD is characterised by memory impairment and the neuroanatomical differences. However, the detection of these signs is often difficult and requires complex and expensive neuropsychological tests or brain imaging technologies. In this context, interest in language and how it changes over the course of the disease has increased in recent years. Research has shown that language deficits occur in the early and even prodromal stages and are therefore of interest for early diagnosis. The aim of this bachelor's thesis is to provide an overview of the research findings to date: Why is early diagnosis of Alzheimer's important? To what extent does language change in the early stages of the disease? How can language be used as a method of early diagnosis? Literature: https://pmc.ncbi.nlm.nih.gov/articles/PMC4611852/#B44

Beschreibung: Alpha oscillations were labelled the idling brain rhythm, because they occur during resting states. However, since alpha synchronization with increasing working memory demands was observed, this concept had to be revised. It is now commonly agreed that power modulations in alpha oscillatory activity serve as an inhibitory neural mechanism, se- lectively routing information within cerebral circuits. In visuo-spatial attention, alpha oscillations enhance the processing of relevant targets and suppress potential distractors. However, there are inconsistencies regarding alpha power modulations with increasing load in common working memory (WM) tasks. Particularly, high WM load is associated with either decreased or increased alpha power, depending on the type of WM task. Through research by Popov et al. (2021), an explanation for these inconsistencies has been proposed. According to them, the differences in posterior alpha power modulations are due to differing eye movements between WM tasks.

Beschreibung: The learning process is one of the main topics of research in multiple disciplines such as psychology, neuroscience, behavioral ecology, evolutionary theory and computer science. The neural mechanism of memory formation and how it changes with age remains unclear. The use of neurophysiological measures can offer valuable insights into the learning process due to the ability of linking neural signals to complex behaviors. Electroencephalographic studies show that some components of event-related potentials (ERP) may provide information about the learning process itself and objectively measure learning success. These components include P300, a positive deflection with a latency of around 300 after stimulus onset. Polich, J. (2007). Updating P300: An integrative Theory of P3a and P3b. Clin.

Beschreibung: Neuropsychological studies indicate that healthy ageing is associated with a decline of inhibitory control of attentional and behavioural systems, to inhibit prepotent responses is critical for successful goal-directed behaviours. A widely accepted measure of inhibitory control is the antisaccade task that requires both the inhibition of a reflexive saccadic response toward a visual target and the initiation of a voluntary eye movement in the opposite direction. This thesis aims to bring together and discuss evidence of decreasing inhibitory control in older adults using electroencephalography and eye-tracking recordings from the antisaccade task.

A widely accepted measure of inhibitory control is the antisaccade task, in which participants inhibit a reactive saccade to a visual target to perform a voluntary saccade in the opposite direction. In addition, the EEG beta-band activity is known to be associated with the processing components during anti- and prosaccades. The aim of this thesis is to bring together and discuss evidence of decreasing inhibitory control in older adults using electroencephalography and eye-tracking recordings

Beschreibung: ADHD is a frequent disorder in children and adolescents characterised by increased levels of hyperactivity and inattention. Yet, the underlying mechanisms of ADHD are not well understood. The aim of this thesis it so bring together current findings on morphologic characteristics of the cortex during brain development in ADHD. The findings shall be discussed critically with respect to their responsibility in the heterogeneity of symptoms in this disorder.

Beschreibung: Neural oscillations and their interaction play a key role in various cognitive processes. Phase-amplitude-coupling, a form of cross-frequency-coupling, has been reported to be directly linked to memorisation. The aim of this thesis is to bring together and critically discuss evidence of phase-amplitude-coupling in electroencephalography recordings that indicate memory processes, with the main focus on working memory.

Beschreibung: Contralateral delay activity (CDA) is a widely studied phenomenon in memory research. Its sensitivity to working memory load is a replicated finding and advances our understanding of underlying processes. Furthermore it may be useful in the investigation of age related decline in working memory capacity.
