Generalization and properties of the neural response
… by Smale et al. in the paper "Mathematics of the Neural Response", Foundations of Computational Mathematics, 2010. We propose a generalized definition of the neural response and derived kernel that allows us to integrate some of the existing hierarchical algorithms in practice into our framework. …

Neural response variability in the navigational system of the brain
… to the naked eye. To progress in making sense of neural data, a fundamental statistic is the instantaneous firing rate of a neuron, which has helped reach groundbreaking insights into how the brain processes and represents information. Many statistical methods have been developed to estimate this …

Attention Strongly Modulates Reliability of Neural Response to Naturalistic Narrative Stimuli
… but it provides little insight into the neural underpinnings of our attentional engagement with modern naturalistic content. Here, we show in human subjects that the reliability of an individual's neural responses with respect to a larger group provides a highly robust index of the level …

Mothers’ neural response to valenced infant interactions predicts postnatal depression and anxiety
It is currently unknown whether differences in neural responsiveness to infant cues observed in perinatal affective disturbance are specific to depression/anxiety or are better attributed to a common component of internalizing distress. It is also unknown whether differences in mothers’ brain …

Optimizing the neural response to electrical stimulation and exploring new applications of neurostimulation
… parameters is imprecise, and the patient responses are highly variable. I developed a method of designing custom stimulus waveforms and assessing the nerve response to optimize stimulation selectivity and efficiency. VNS experiments were performed in rats aiming to increase the selectivity …

Triggering and measuring neural response indicative of inhibition in humans during conversations with virtual humans
… if a confrontational virtual human can evoke a response in the prefrontal cortex, indicative of inhibiting an antisocial response. It follows previous studies by Aleksandra Landowska (2018) and Schilbach (2016) demonstrating that a prefrontal cortex response indicative of inhibition can be …

Bioastronautics: Biological Modeling of the Neural Response to Space Radiation and its interaction with Alzheimer's Disease Risk Genes
… and develop both new and existing in vitro neural models for radiation research – particularly in the context of neurodegenerative disease. First, we adapt an existing 3D in vitro model of Alzheimer’s disease, which captures the beta-amyloid (Aβ) and phosphorylated tau protein aggregation …

When the Brain Plays a Game: Neural Responses to Visual Dynamics during Naturalistic Visual Tasks
… We investigate the modulation of stimulus-evoked responses during a naturalistic task (i.e., kart race game) using non-invasive scalp recordings.</p> <p>In recent years, multivariate modeling approaches have become increasingly popular for assessing neural response to naturalistic stimuli. …

Perceptions of Parental Care and Overprotection in Childhood: Influences on the Neurobiological Adaptation to Motherhood
… parenting. Few studies have investigated neural and biological mechanisms contributing to observed associations between childhood care and the adaptation to motherhood. The following studies address this gap by examining how perceptions of childhood parental care and overprotection are …

Multi-Scale Modeling for Analysis and Design of Transcranial Electric and Magnetic Brain Stimulation
… of how the stimulation parameters determine the neural response and how these parameters can be manipulated to activate specific neural circuits. This dissertation presents multiscale computational models that predict the neural response to TMS and tES at the single-cell and population levels for …

Cannabis Exposure During Pregnancy and Neural Mechanisms of Parenting: Assessing Neural Responses to Infant Cues and Parenting Outcomes
… use during the prenatal period and functional response to infant related stimuli. Study One examines the association between cannabis use during the prenatal period, functional response to infant cries, and explores behavioral interactions between gestation parent and child. This study found …

Examining the Associations Between Puberty and Social Reorientation at the Neural Level
… towards peer relationships, by reorienting neural responses to prioritize peer social information. However, limited studies have investigated whether puberty predicts social reorientation at the neural level, in terms of neural responses to teens’ own parent and friend. The current study …

Exploring Interactions Between Attention and Perception in Saccadic Eye Movements and Frontal Eye Field Cell Responses
… processes between stimulus appearance and motor response. Conversely, compelled tasks allow the separate assessment of perceptual and motor stages of the behavioral and neural response to targets requiring top-down (CS task) or bottom-up (CO task) selection.

Functional Magnetic Resonance Imaging of Peripheral Neuropathic Pain in the Spinal Cord and Brainstem
To date, most studies investigating the neural signature of pain in humans have focused on the brain, and those studies concerned with more caudal areas (such as the spinal cord (SC) or brainstem) have used only experimental models of pain. The objectives of this study were 1) to determine the …

The Effects of Musical Intervals from Consonant to Dissonant on the Neural Activity of Earthworms
… and dissonant. Studies have shown a greater neural response in human participants to consonant intervals (Bidelman and Heinz 2011, Bidelman and Krishnan 2009). In this study, the ventral nerve cord of <em>Lumbricus terrestris</em> was exposed to six dichotic intervals in the form of …

Neural Dynamics, Adaptive Computations, and Sensory Invariance in an Olfactory System
… systems. What features of these spatiotemporal neural response patterns encode stimulus-specific information (i.e. ‘neural code’), and how they are translated to generate behavioral output are fundamental questions in systems neuroscience. The objective of this dissertation is to examine this …

Decision-making Across Development: The Impact of Ambiguity and Social Context
… magnetic resonance imaging to show that neural response to reward for self and for friend are similar in a sample of young adults (ages 18 to 28), and that neural response to reward linearly decreases with age when participants are watched by their friends but not when they are alone. In …

Normalization Among Heterogeneous Population Confers Stimulus Discriminability on the Macaque Face Patch Neurons
… at a time on a homogeneous background to study neural response properties. It thus remains unclear how face selective neurons respond to multiple stimuli, some of which might be encompassed by their receptive fields (RFs), others not. How is the neural representation of a face affected by the …
