Cursed complexity. Computational properties of subcortical neuronal microcircuitry in sensorimotor control
One of the big obstacles for understanding the nervous system is its inherent complexity. It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. Since there exist problems …

Modularity of the microcircuitry of the lateral cortex of the mouse inferior colliculus
… modules, and to understand how this particular microcircuitry might subserve acoustic and multisensory processing. In Chapter 2, we sought to better characterize the modules in the mouse inferior colliculus and determine if the connectivity of other neural structures with the lateral cortex is …

Development and plasticity of the functional laminar mesoscale organization of the primary auditory cortex
… the underlying laminar-specific differences in microcircuitry changes, and indicating an overall dissociation of plasticity of single-cell, mesoscale, and macroscale network properties.

Cellular and Circuit Level Responses to Neural Stem Cell Transplantation in the Rodent Cortex
… current threshold required to activate cortical microcircuitry by ten-fold. Conversely, moderate levels of engraftment (<15%) preserved network properties and induced only subtle changes in facilitation during repetitive stimulation. A binning analysis of cortical activity showed that deep …

Learning image segmentation and hierarchies by learning ultrametric distances
… The cortical column, a basic unit of cortical microcircuitry, will produce a single 3d electron micrograph measuring many 100s terabytes once imaged and contain neurites from well over 100,000 different neurons. It is estimated that tracing the neurites in such a volume by hand would take …

The Mechanisms And Roles Of Feedback Loops For Visual Processing
… neural feedback loops work in terms of synapses, microcircuitry, and systems dynamics, we developed a chick midbrain slice preparation to study and characterize one important feedback loop within the avian visual system: isthmotectal feedbackloop. The isthmotectal feedback loop consists of the …

Selective Neuronal Vulnerability in Neocortices from Patients with C9ORF72-related Neurodegeneration
… which in turn reinforces the notion of microcircuitry being predictive of vulnerability (rather than spatial proximity or developmental origin). I also cross-examined the biological pathways highlighted in the snRNA-seq analysis with findings from literature (Chapter 5). Identified …

Genetic Modulation of the Neonatal Neural Processing of Speech at High and Low Familial Risk for Developmental Dyslexia
… associated with abnormalities in the cortical microcircuitry, as hence in the functional connectivity and brain-to-speech (B2S) synchrony at birth. Identifying potential neonatal neural markers in association with dyslexia would be important for the understanding and supporting phonological …

Songbird Brain Organization and its Molecular Convergence with Humans for Vocal Imitation Learning
… for vocal imitation. The existence of analogous microcircuitry utilized by songbirds and humans for vocal production learning confirms the value of the songbird as an invaluable model for speech-motor dysfunction. Overall, this work offers important insights into the evolution of the brain and …
