Cortical Dynamics of Language
… the dynamical mechanisms supporting cortical network behavior will significantly advance the understanding of how both focal and disconnection injuries yield neurological deficits, informing the development of therapeutic approaches.</p>

Modeling Integrated Cortical Learning: Explorations of Cortical Map Development, Unit Selectivity, and Object Recognition
… of simple and complex cells within each cortical visual area. The Deep Convolutional Neural Networks (DCNN) architecture is the most computationally successful implementations of HTC, and has been adopted as a tool for linking cognition to neural processes. However, DCNNs are exceedingly …

The Diversity of Cortical Interneurons
… discrimination, and memory consolidation. The cortical interneurons are key elements of the cortical system. These interneurons stabilize networks, but at the same time they also add non-linear effects to the excitatory system to make the cortical network more dynamic. To achieve this, cortical …

Cholinergic Control of Cortical Circuit Activity
… role in the moment-to-moment control of ongoing cortical state transitions that occur during periods of wakefulness. Yet, the underlying circuit mechanisms of synaptic cholinergic function in the neocortex remain unclear. Moreover, acetylcholine continues to be widely viewed as a slow and diffuse …

Population Coding In Laminar Cortical Circuits
… of neuronal networks is organized according to cortical layers raises the possibility that sensory information could be processed differently in distinct layers. The goal of my thesis research is to understand how laminar circuits encode information in their population activity, how the …

TIMING RELATIONSHIPS IN HUMAN CORTICAL PROCESSING
… cardiac cycle reflect temporal relationships in cortical processing, these studies are not conclusive. The reason is that almost all of these suggestions have been based upon the demonstration that a measure of visual processing varies with the phase of the alpha cycle or the cardiac cycle at …

Computational studies of cerebellar cortical circuitry
… cortex. For a large majority of cerebellar cortical neurons the optical oscillations reflect the oscillations present in their spontaneous activity. The oscillations appear to be intrinsic to the cerebellar cortex and in the awake animals increased oscillatory cerebellar activation becomes …

Subcortical Inputs Governing Cortical Network Activity
… characterizes the nature and mechanisms of awake cortical network dynamics, as well as the sources of sensory inputs in different cortical layers of the rat somatosensory system. Mammalian brains generate internal activity independent of environmental stimuli. Internally generated states may bring …

Frontal cortical asymmetry and impulsive aggression.
… outbursts and measures resting frontal cortical activity. Impulsive aggression (IA) is described as a reactive or emotionally charged aggressive response characterized by a loss of behavioral control. Previous physiological studies have found IAs have sensory and informational processing …

Cortical structure: Linking MRI and cytoarchitecture
… the problem of linking microscale post mortem cortical cytoarchitecture with millimeter-scale measures of cortical anatomy accessible through in vivo MRI. Chapter 1 introduces the problem and previous work done to address it. The following two chapters apply classical atlases of cortical …

Cortical recording with conducting polymer electrodes
The ability to record from the same neuron for extended periods of time is essential to understanding how the brain reorganizes during motor learning. Conventional chronic recording microelectrodes are made from metal or silicon. However, the large stiffness mismatch between the electrodes and …

Cortical Responses to Illusory and Surface Color
In order to see the world as we do our visual system constantly performs many amazingfeats that are largely unknown to us, the viewers. In order to create and update a seamless andcoherent representation of the world, our eyes and brain have to deal with many obstacles thatcould interfere with …

Hierarchy and invariance in auditory cortical computation
… pattern of behavioral errors, and predicts cortical responses, as measured with fMRI. The multi-task optimization procedure we introduce produces separate music and speech pathways after a shared front end, potentially recapitulating aspects of auditory cortical functional organization. …
