Neural Encoding of Prior Experience in Sensorimotor Behavior
… gathered about the environment. At the neural scale, the effects of prior experience have been described by the theory of predictive processing in terms of efficient coding principles that govern the response properties of neurons. The major contribution of this thesis is to bridge these …

Neural Encoding of Continuous Attended Speech in Monolingual and Bilingual Listeners
… I investigate how bilingualism influences the neural mechanisms of selective attention to speech, and whether this is further affected by the age of acquisition of a second language, and typological similarity between the two languages. These questions are addressed in four experiments by …

Neural Encoding of Complex Signals in the Healthy and Impaired Auditory Systems
<p>Individuals with sensorineural hearing loss (SNHL) typically experience difficulty in understanding speech. Our current knowledge of deficits in speech perception and encoding consequent to SNHL is restricted to psychophysical studies in humans and single-unit experiments in animals. However, …

Taking attention away from the auditory modality : investigations of the effect on speech processing using machine learning
… dividing attention to a visual task affects neural processing of speech signals. We show that dividing attention between auditory and visual tasks leads to both behavioral and electrophysiological costs in the processing of continuous speech stimuli. The results also demonstrate that the …

Neural and Behavioural Effects of Bilingualism on Selective Attention
Bilingualism has been shown to modulate the neural mechanisms of selective attention, with differences between monolinguals and bilinguals observed even when they display equivalent behavioural performance in a selective attention task. This suggests that the crucial consequence of learning and …

Sensitivity to (sub)lexical cues as a function of cognitive profile and language abilities
… data show that phonological deficits impact the neural encoding not only of phonological information, but also lexico-semantic information. The findings from this thesis provide comprehensive evidence that the extent to which individuals rely on form-based information compared to other linguistic …

Neural Mechanisms Promoting Biased Social Memories in Intergenerational Childhood Abuse
… mechanisms. This study investigates whether neural and cognitive biases in social processing – specifically, the encoding and recall of social feedback – serve as pathways linking childhood abuse histories to harsh parenting of the next generation. Using fMRI and a verifiable, ecologically …

Generic Adaptive Handoff Algorithms Using Fuzzy Logic and Neural Networks
… intelligence utilized in this research, neural networks and fuzzy logic, are introduced. The scope of existing simulation models for macrocellular and microcellular handoff algorithms is enhanced by incorporating several important features. New simulation models suitable for performance …

Neural Activity Within and Between Visual and Executive Areas Is Modulated Post-Locomotion in Rhesus Macaques
… This project combines behavioral metrics and neural data with a detection task paradigm divided into distinct pre- and post-locomotion phases, providing key insights into how perception of visual stimuli and behavioral choice based on visual perception is acutely regulated following periods of …

Investigating neuronal network dynamics : scale-invariance, preferred firing rates, and plasticity via phase-shift encoding
… is critical for advancing our knowledge of neural plasticity and computation. Scale-invariant properties, which suggest self-organised criticality (SOC), have been observed in these networks, but the mechanisms underlying these dynamics have remained unclear. Despite theoretical models, …

An Exploration of Neural Heterogeneity and its Consequences on Network Dynamics and Neuromodulation
… information transmission, and effective neural encoding. Importantly, although neural heterogeneity is often regarded as a static property and modelled as a fixed meta-parameter, this is not the case in the brain. Rather, heterogeneity is, in many instances, a dynamic property of the …

Neuronal and Molecular Basis of Nociception and Thermosensation in Drosophila melanogaster
… to be noxious. Nociception is defined as the neural encoding and processing of noxious stimuli. This process starts from the activation of pain detecting peripheral sensory neurons (nociceptors) that can detect noxious mechanical, thermal or chemical stimuli. On the other hand, animals also …

Neural Correlates of Reach Planning and Execution
… through space. This dissertation investigates neural activity in the dorsal premotor cortex of the macaque monkey while simple and complex reaching movements are planned and executed. A novel virtual-reality obstacle-avoidance task is used to decorrelate the direction of the initial segment of …

Identification of Dendritic Processing in Spiking Neural Circuits
… to understanding the underlying principles of neural computation. In this thesis, we develop a novel theoretical framework for the identification of dendritic processing directly from spike times produced by spiking neurons. The problem setting of spiking neurons is necessary since such neurons …

Optimizing Reservoir Computing Architecture for Dynamic Spectrum Sensing Applications
… State Machines (LSMs), which emulate spiking neural networks like the ones in the human brain, prove to be highly effective for real-time data monitoring for such temporal tasks. The inherent advantages of LSM-based recurrent neural networks, such as low complexity, high power efficiency, and …

Exploring the neural mechanisms underlying the speech processing and phonological deficits that characterise individuals with dyslexia
… this thesis is to gain deeper insights into the neural mechanisms underlying dyslexia within the framework of Temporal Sampling (TS) theory, by focusing on adults. The study involved 48 adult English speakers, comprising 24 individuals with dyslexia and 24 controls without dyslexia. A …
