Touchscreen Assessment of Motivation and Reinforcement-Related Choice Behaviour in Mice
This dissertation describes the development and optimisation of a set of touchscreen tasks for the assessment of motivation and reinforcement processes in mice. Changes in motivational state and reinforcement sensitivity are characteristic of depressive symptoms in a number of neuropsychiatric and …

Socially guided machine learning
Social interaction will be key to enabling robots and machines in general to learn new tasks from ordinary people (not experts in robotics or machine learning). Everyday people who need to teach their machines new things will find it natural for to rely on their interpersonal interaction skills. …

Feedback control design for closed-loop oscillations via dominant system theory
… an important class of behavior in both nature and engineering. For engineering applications like robotic locomotion, it is usually desirable to induce oscillations in a controlled manner. While plenty of feedback control methods have been developed for equilibrium behaviors in control theory, …

Control of neuronal circuits: from biology to robotics
… that is characteristic of biological systems and that is key to their effectiveness. In this thesis we take a step towards reconciling biophysics with bio-inspired control, using the language of control theory to do so. The proposed controller is event-based, and has the physical realisation …

Endogenous control of stochastic gene expression in the development of Caenorhabditis elegans
… expression determines the migratory direction and the subsequent fate choices of cells that descend from the original neuroblast. Intrigued by the earlier observation that perturbation to Wnt signaling disrupts the wild-type stereotypy in migratory decision, I speculated that variable gene …

Hedonics, Reward Prediction, and Reinforcement Learning in Schizophrenia: Relationships to Anhedonia and Avolition
<p>Anhedonia (a reduced experience of pleasure) and avolition (a reduction in goal-directed activity) are common features of schizophrenia that have substantial effects on functional outcome, but are poorly understood and treated. Here, we examine the potential contributions of three processes …

The Role of Gene Expression Noise In Mammalian Cell Survival
<p>Drug resistance and metastasis remain obstacles to effective cancer treatment. A major challenge contributing to this problem is cellular heterogeneity. Even in the same environment, cells with identical genomes can display cell-to-cell differences in gene expression, also known as gene …

The Relationship between Neuropsychological Measures of Executive Functioning and Anxiety with Neurophysiological Markers of Cognitive and Affective Control
… cognitive processing may aid our understanding of the neurobiological basis of these disorders and assist in formulating integrated treatments. One event related potential theorized to function in the cognitive control of adaptive behavior, the feedback negativity (FN), shows differences …
