Neural dynamics supporting flexible cognition
… EEG (iEEG) recordings in humans to study the neural dynamics of flexible cognition during high-order sensory processing. First, we validated assumptions about the locality of iEEG signals and clarified how electrode type, referencing scheme, and filtered frequency influence electrode listening …

From Intention to Action: Neural Dynamics of Voluntary Action
… However, the field has overlooked whether those neural precursors were predictive of the upcoming actions, a feature expected of a signal indexing a decision. In this thesis, I present four studies addressing whether results in the neuroscience of volition support claims that early decisions are …

Microinvasive probes for the longitudinal interrogation of neural dynamics
… probes are critical to investigating the neural dynamics of functions such as learning, motivation, and movement control over the extended timescales at which they develop. Proven functional lifetimes of over a year are also necessary for eventual clinical use in human patients to help …

Employing Intracranial EEG Data to Decipher Sleep Neural Dynamics
… data recorded allows one to directly observe the neural activity of deep brain structures such as the hippocampus and to detect single unit activity and local field potentials, thus providing a level of physiological detail normally available only in animal studies. In this thesis we employ …

Investigation of Sleep Neural Dynamics in Intracranial EEG Patients
… across labs for use in studies pertaining to neural dynamics during sleep.

Neural Dynamics in the Developing Piriform Cortex of Awake Rats
… These findings indicate that early developmental dynamics observed in piriform cortex activity are highly similar to those previously observed in neocortical sensory areas. This suggests that the principles underlying cortical development are evolutionarily conserved, and that sensory cortical …

Simulating and calibrating stretchable optical fibers for studying neural dynamics
… greatly limited by the materials available for neural probing and optical recording, such as silica, which are stiff and can damage neural tissue with vigorous test subject movement. In this work, we develop a polyvinyl alcohol (PVA) hydrogel optical fiber for photometric recording of neural …

Spatiotemporal Neural Dynamics of Audiovisual Perception and Cross-modal Mental Imagery
… and auditory information. However, how the neural activity and representations unfold during the perception of naturalistic audiovisual stimuli remains less understood. Beyond perception, we often recall past experiences and reconstruct them through mental imagery. The extent to which …

Behavioural and neural dynamics of category learning across the menstrual cycle
… initial behavioural effect and identifies its neural correlates, confirming that activation in brain regions supporting category learning varies across the menstrual cycle and with ovarian hormone levels. Not only does this body of work provide the first evidence of menstrual cycle effects on …

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 …

Neural Dynamics in the Basal Ganglia Underlying Birdsong Practice and Performance
… providing a powerful system to explore how neural ensembles regulate motor variability. Here, I used this system to identify neural mechanisms underlying practice and performance. First, I used deep brain imaging techniques to demonstrate that spiny neurons (SNs) in the basal ganglia (BG) …

Neural dynamics of the anesthetized brain and the control of conscious states
… However, the mechanisms underlying GA at the neural systems level are underexplored and largely not understood. To link neural dynamics to the loss of consciousness, we measured spiking activity and local field potentials (LFPs) from multiple cortical and thalamic regions while monkeys were …

Neural Dynamics of Mental Imagery, Visual Perception, and Rapid Eye Movement Sleep
… deeper understanding of the differences between neural activity during REM sleep and during the awake state. We set out to investigate the temporal directionality of communication and coupling in neural activity between different areas of the brain during REM sleep and awake activities. One …

Examining the Transient Neural Dynamics Underlying Working Memory Maintenance for Complex Visual Stimuli
… maintenance during the delay period, and how neural activity and connectivity are related to memory is critical for advancing both basic knowledge as well as informing declines in memory and cognition related to neurodegenerative diseases and healthy aging. An open question in the field of WM …
