The neurobiological bases of compulsive eating
… construct that shares many behavioral, neurobiological, and theoretical features with compulsive drug use. The focus of this dissertation is to progress a framework for compulsive eating behavior, including identification of risk factors for its development and examination of functional …

Neurobiological mechanisms of hallucinations in schizophrenia
All perception is a construct of the brain. Yet occasionally, sensory constructions emerge without origin in the physical world and are experienced as hallucinations. Hallucinations occur transdiagnostically, cross-culturally, and in all sensory modalities. They are common in people with …

Neurobiological aspects of social anxiety disorder
This thesis investigates the functional neuroanatomy of SAD [Social Anxiety Disorder] using an activation likelihood-estimate meta-analysis (ALE meta-analysis), and explores the structural basis of SAD using a cortical thickness and subcortical gray matter volume analysis.

Neurobiological mechanisms underlying episodic memory retrieval
… has focused on memory formation, with the neurobiological basis of memory retrieval largely ignored due to experimental limitations. Here, I present our recent advances in the study of memory retrieval using technologies to engineer the representation of a specific memory, memory engram …

Multifocal Multiphoton Microscopy for Neurobiological Imaging
Observing neuronal structures and monitoring changes in synaptic connectivity with respect to time have a significant impact on understanding the basis of structural brain abnormalities and the development of therapeutics for their correction. Today, multiphoton excitation fluorescence microscopy …

Investigations of the neurobiological and behavioural actions of cocaine
… these experiments examined the behavioural and neurobiological effects of cocaine in the rat. The behavioural and neurochemical interactions between cocaine and buprenorphine were examined using a conditioned place preference (CPP) procedure and in vivo microdialysis. Cocaine and buprenorphine …

Towards a mechanistic understanding of the neurobiological mechanisms underlying psychosis
… disorders. Yet, despite decades of research, the neurobiological mechanisms via which these symptoms come to manifest themselves remain to be elucidated. I argue in this thesis that using a mechanistic approach towards understanding psychosis that borrows heavily from the predictive coding …

Orientation in migratory birds: orientation mechanisms and their underlying neurobiological background
This thesis aims to understand the neurobiological and physiological mechanisms underlying the magnetic compass orientation of night-migratory birds. Behavioural observation show that night-migratory garden warblers (Sylvia borin) use stereotype sideways movement of the head (head scans) to detect …

Obsessive-compulsive homeland security: insights from the neurobiological security motivation system
… It proposes a model for how activation of the neurobiological security-motivation system can lead to securitization in response to a security speech act. It explores the model by qualitatively analyzing three examples of securitization processes in the homeland security field for security …

Early neighborhood disadvantage and risk for internalizing problems: underlying neurobiological mechanisms
… difficulties across the lifespan. However, the neurobiological mechanisms underlying these associations remain unclear. In this study, I investigated the associations of early neighborhood-level disadvantage and air pollutant exposure with neural network topology and stress-related outcomes in …

Dementia in Parkinson s Disease: relationship between clinical and neurobiological aspects
Il deficit cognitivo è uno degli aspetti più comuni e importanti della malattia di Parkinson (PD), influisce notevolmente la qualità e l aspettativa di vita del paziente. Lo spettro delle disfunzioni cognitive nei PD è stato recentemente codificato in termini di Mild Cognitive Impairment …

Parkinson's disease and degenerative parkinsonism: relationship between clinical and neurobiological aspects
Il neurovascula coupling indica il processo mediante il quale l unità neuro vascolare modula la complessa relazione tra attività neuronale, fattori emodinamici e segnali intracellulari. Recenti studi individuano la possibile associazione tra alterazioni dell emodinamica cerebrale e il decadimento …

Methamphetamine and amphetamine differentially affect associative learning: behavioral and neurobiological correlates
… of associative learning, and how specific neurobiological mechanisms, namely glucocorticoid or dopamine receptor activation, contribute to these alterations. A second goal was to investigate potential differences in the effects of two psychostimulants; methamphetamine (METH) and amphetamine …

Behavioural, immunological, and neurobiological effects of early life stress in rats
… to isolate key behavioural, immunological, and neurobiological effects into adulthood of early life stress itself. To do this, I used the repeated maternal separation (RMS) model of chronic early life stress, and I focused particularly on those effects of possible relevance to anxiety, …

Experiential and Neurobiological Influences on Economic Preferences and Risky Decision Making
… influences on economic preferences and neurobiological effects on risky decision making. Chapter 2 examines whether experiences during adolescence have a long-term effect on economic preferences. Between 1966 and 1976, China's Sent-Down Movement required seventeen million urban teenagers …

Multi-dimensional aspects of mindfulness: psychometric evaluation, neurobiological underpinnings, and experiential insights
… a psychometric evaluation of self-report scales, neurobiological underpinnings, and experiential insights in a multidimensional approach. The objective encompassed three specific aims: firstly, to evaluate the psychometric effectiveness of two self-report scales; the Mindful Attention Awareness …

Neurobiological effects of food fermentation-derived metabolites for metabolic and mental health
… focus on SCFAs and polyphenols, to alter the neurobiological functions associated with central appetite regulation (hypothalamus) and cognition (hippocampus). Using in vitro assays, we tested the selected panel of metabolites shown to be found in fermented foods, and capable of crossing the …

Neurobiological and metabolic mechanisms of binge-eating in anorexia and bulimia nervosa
… characterisation of the physiological and neurobiological mechanisms that give rise to, or maintain, this behaviour is lacking. This thesis integrates observations across metabolic, neural and behavioural levels in women with and without eating disorders, providing novel insights into how …

An Applied Neurobiological Model Of Dance, Why It Matters, And How It Heals
… mechanisms through which these benefits occur. A neurobiological model of dance, grounded in tools and practices from the field of dance studies, elucidates aspects of dancemaking that are effective in the treatment of specific disorders while promoting health and optimising function. Dance …
