Sensorimotor transformation and information coding across cortex during perceptual decisions
… for uncovering general principles of neural information processing and cognitive function. While the process of mapping sensory stimuli onto motor actions may appear to be simple, its neural underpinnings are poorly understood. The goal of this thesis is to better understand the neural …

Extraction, processing, and analysis of multineuron data
The work reported considers information coding by a population of neurons. Multineuron data were extracellularly recorded from the ventral nerve cord of the cockroach, Periplaneta americana. The nerve cord contains 14 giant interneurons which mediate the wind-evoked directed escape response. The …

Information processing in a midbrain visual pathway
Visual information is processed in brain via the intricate interactions between neurons. We investigated a midbrain visual pathway: optic tectum and its isthmic nucleus) that is motion sensitive and is thought as part of attentional system. We determined the physiological properties of individual …

Nonlinear dynamics and statistical physics of excitable systems
In the search for the mechanisms of neuronal information coding, attention has recently shifted towards the possible role of neuronal firing correlation. The present thesis addresses the question of how coupled neuronal systems synchronize. Neurons can be described as dynamical systems through the …

Naturalistic Inquiry: An Appropriate Method for Evaluating Customer Training A Case Study of a Computer System Value-Added Reseller
… data analysis included the collection of information, coding of data, categorizing the data, identifying patterns and trends, and drawing conclusions based on these patterns. Research findings suggested that naturalistic inquiry can be both effective and very practical an approach to …

Kernels of learning : tracking the emergence of visual recognition through multivariate approaches
… interpretation is greatly facilitated by prior information about a stimulus. What are the neural sites that exhibit experience dependent changes? Using multivariate decoding techniques, I find pervasive evidence of such changes throughout the visual system. Critically, cortical regions …

Inkjet printing polymerized pcda as a means of serialization
… allowing for the embedding of larger amounts of information than their one-dimensional barcode predecessors. Combining the colorimetric response of PCDA polymer with the information coding powers of Q-R codes, an improved version of the Q-R Code is made, which was used not only for serialization …

Effects of aberrant visuo-vestibular information on higher cognition
… visual systems. The peripheral structures code information pertaining to the spatial relationships and motion of the whole body. The central networks modulate and integrate this ‘space-motion information’. Coding or modulatory disturbances, due to pathology or incongruous environmental …

Effect of Background Synaptic Activity on Excitatory-Postsynaptic Potential-Spike Coupling
<p>Neurons receive large amount of synaptic inputs <em>in vivo</em>, which may impact the coupling between EPSPs and spikes. We mimicked the<em> in vivo</em> synaptic activity of the cell with the dynamic clamp system. We recorded from pyramidal cells in neocortical slices<em> in vitro</em> to …

NANOSTRUCTURED COMPOSITE FILMS FOR BRAIN-MACHINE INTERFACE APPLICATIONS
Biohybrid electronic technologies, fostering information flow and processing between natural and artificial components [1] are essential for developing energy-efficient, compact interfaces that integrate bioelectrical activity for personalized medicine. In this frame, advances in thin-film sensors …
