Personality, Affect and EEG: An Integration of Three Models to Predict Neural Patterns of Activity
This research assessed whether individual differences in frontal and posterior electroencephalogram (EEG) alpha were associated with basic dimensions of personality, extraversion and neuroticism. A theoretical model proposed that extraversion and neuroticism (measured by the NEO-PI-R) were related …

Computational Framework Enabling an EEG-based BCI for Neurofeedback in Language Disorders: The case of dyslexia
… applied to the child EEG datasets to identify neural patterns associated with atypical speech processing and dyslexia in children. This statistical modelling was informed by the neuroscience of speech literature and the temporal sampling theory of dyslexia and two potential neural patterns to …

Decoding the emotional modulation of memory encoding: a multivariate fmri study of arousal and valence
… and arousal (calm/exciting) to the neural patterns supporting memory encoding are not fully understood. We leveraged multivariate pattern analysis (MVPA) to dissociate these influences. We analysed fMRI data from a large cohort of participants during an emotional picture encoding …

Sensory modulation of muscle synergies for motor adaptation during natural behaviors
… algorithm. But to what extent synergies are neural constraints, or merely structures reflecting experimental constraints, has remained an open question. I address this question with the hypothesis that, muscle synergies are robust neural patterns constraining motor outputs. The strategy …

Remembering the past : multimodal imaging of cortical contributions to episodic retrieval
What is the nature of the neural processes that allow humans to remember past events? The theoretical framework adopted in this thesis builds upon cognitive models that suggest that episodic retrieval can be decomposed into two classes of computations: (1) recovery processes that serve to …

Individual Differences in Preschool Aged Children's Inhibitory Control: Adding Borders to the Day/Night Task
… electroencephalogram (EEG) illuminated the neural patterns of the task in children at age four. This study demonstrated that the borders condition of the day/night task is an appropriate executive function task that can be used with preschool aged children.

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 …

The Neural Processing of Face-like Stimuli
… emotional and social information, yet the neural mechanisms underlying their perception across different types of face-like stimuli remain incompletely understood. This dissertation will report an EEG - multivariate pattern analysis (MVPA) study that investigated how emotional expressions …

A social neuroscience approach to understanding adolescent delinquency and bullying
… comparing their performance (both behavioral and neural) to their normatively developing peers. In study 1, I examined how emotion regulation difficulties in adolescence were often contextual, as actively delinquent adolescents show differential behavioral and neural patterns corresponding to …

Art as a Generator of New Mental Patterns: From an epistemological perspective of Modern Physics, Neuroscience and the Buddhist system of thought.
… argument, I draw upon notions like Damasio’s “neural patterns”, Chalmer’s “information spaces” and the “ego tunnel model” defined by Metzinger. Attempting to interpret the interdependence between subject and object, it can be taken out the existence of a gap between complex, abstract scientific …

The neural and psychophysical bases of memorability
… I describe the first characterization of the neural and psychophysical bases of memorability. First, I show that memorability is highly consistent in the domain of face images, despite their similar perceptual features and same basic-level category, and examine what facial attributes are …

Modelling resting-state neural oscillations to uncover circuit mechanisms of aging and rTMS response in late-life depression
… Resting-state oscillations are rhythmic neural patterns observed when the brain is not engaged in a specific task, measurable via magnetoencephalography (MEG) or electroencephalography (EEG). Alpha rhythms, a prominent feature of these oscillations, are altered in several psychiatric and …

An electrophysiological basis for human memory
… temporal lobe in order to examine if temporal patterns of activity may serve as a general neural code that is replayed during memory retrieval. We found that verbal memories corresponded to item-specific sequences of cortical spiking activity, these sequences replayed during memory retrieval, …

Thinking in patterns : representations in the neural basis of theory of mind
… Yet, we have little insight into how these neural substrates function at a computational level. This thesis lays the groundwork to address that question, both empirically and theoretically, first by demonstrating that functional neuroimaging can find behaviorally relevant features of mental …

Origins of empathy development in infancy
… individual differences in 8-month-old infants’ neural responses to peers’ emotional non-verbal vocalizations by using event-related potential (ERP) method and parental reports of infants’ temperament. Results showed that infants responded differently to peers’ laughing and crying vocalizations, …

Towards a Better Understanding of Facial Movements: Computational Models for Perception, Characterization, and Neural Production
… interactions. Despite their significance, the neural mechanisms governing facial movements remain poorly understood, hindered by the complexity of muscle coordination and the limitations of traditional, subjective, and labor-intensive analysis methods. To objectively understand facial motor …
