The neurophysiology of internally-driven actions
Acting in the world in a way that matches our goals, overriding impulses, is one of the first abilities that we must learn while growing up. We often change the course of our actions because of external influences or because we simply “change our mind”. As John H. Patterson said, “Only fools and …

The neurophysiology of intersensory selective attention and task switching
<p>Our ability to selectively attend to certain aspects of the world and ignore others is fundamental to our day-to-day lives. The need for selective attention stems from capacity limitations inherent in our perceptual and cognitive processing architecture. Because not every elemental piece of our …

Developments in signal processing for computerised diagnosis in clinical neurophysiology
The aim of this study was to apply signal processing techniques to a potential known as the contingent negative variation (CNV) in order to aid detection of schizophrenia, Parkinson's disease (PO) and Huntington's Disease (lID). A data recording system was constructed and used to obtain data from …

Emotion investigated with music of variable valence : neurophysiology and cultural influence
… imprinting. The current thesis investigates the neurophysiology of the valence percept, and the modulating influence of culture on several distinguishable sub-processes of music processing, so-called functional modules of music processing, engaged in the mediation of the valence percept.

Searching for knowledge. The neurophysiology behind the exploration of hippocampal cognitive maps.
Exploring and interacting with the environment is crucial for animals’ survival. Neurons in the hippocampal formation support spatial exploration through locomotion, and eye movements in primates, as well as memory. However, how the hippocampus supports exploration across different cognitive …

Applying Machine Learning and Neurophysiology to Improve Accuracy of Predicting Human Behavior
<p>Predicting human behavior presents significant challenges in various domains. Chapter 1 adopts a novel methodological approach, utilizing neurophysiological responses measured and utilized machine learning to predict hit songs. Statistical analyses reveal the effectiveness of machine learning …

Socioeconomic Neurophysiology: Exploring the relationship between a child’s environment and their neurocognitive development
… the impact of socioeconomic status (SES) on the neurophysiology of children’s brains. Human beings develop within a variety of social and economic environments. This variability is inevitably reflected in cognition and associated brain activity. This includes stark negative impacts on the lower …

Resting State Neurophysiology of Agonist-Antagonist Myoneural Interface in Persons with Transtibial Amputation
The agonist-antagonist myoneural interface (AMI) is a novel amputation surgery that preserves sensorimotor signaling mechanisms of the central-peripheral nervous systems. Our first neuroimaging study investigating AMI subjects (Srinivasan et al., Sci. Transl. Med. 2020) focused on task-based neural …

EFFECTS OF ENHANCING ANANDAMIDE LEVELS ON HIPPOCAMPAL NEUROPHYSIOLOGY AND SHORT-TERM MEMORY PROCESSING IN RATS
The endocannabinoids affect spatial-working memory by altering neuronal activity of pyramidal neurons present in the hippocampus. In this study extracellular action potentials were recorded using multi-neuron electrodes implanted in the CA1 and CA3 subfields of the hippocampus. The acute effects of …

Dissociable Influence of Reward and Punishment Motivation on Declarative Memory Encoding and its Underlying Neurophysiology
<p>Memories are not veridical representations of the environment. Rather, an individual's goals can influence how the surrounding environment is represented in long-term memory. The present dissertation aims to delineate the influence of reward and punishment motivation on human declarative memory …

Peripheral polyneuropathy in type 2 diabetes mellitus and impaired glucose tolerance. Correlations between morphology, neurophysiology, and clinical findings
Diabetic peripheral polyneuropathy (PN) is a common and serious complication of diabetes. The prevalence of PN is rising with the global burden of type 2 diabetes. The causal mechanisms of PN are not fully understood, but both vascular and metabolic factors play a role. New methods of investigating …

Bio-social aspects of Attention Deficit Hyperactivity Disorder (ADHD): Neurophysiology, maturity, motor function and how symptoms relate to family interaction
The purpose of this thesis has been to study biological and social factors of importance for Attention Deficit Hyperactivity Disorder (ADHD). Thirty children (age 6-11) with ADHD were examined with parent ratings, neurological examination, cognitive testing, cerebral blood-flow, and EEG. These …

Functional Peptidomics: Combining Discovery-Based Mass Spectrometry and Neurophysiology to Explore Communication of Phase -Resetting Cues in the Rat Suprachiasmatic Nucleus
This thesis justifies functional peptidomics as a useful approach to understanding intercellular signaling mechanisms regulating SCN clock phase. Directly detecting dynamic release properties of peptides from the SCN brain slice provides new insights on a complex phenomenon phenomenon. The …

Expression of genetic peripheral neuropathies in South African Children
… Diagnostic work-up consisted of clinical, neurophysiology, where available histology and genetics screens. Of 63 recruited children, 19 % had definite (genetic confirmed) and 81% probable (neurophysiology and or histology confirmed) hereditary causes for neuropathy. Of the 63 individuals, …
