Role of Mouse Visual Cortex in Perception of Stimulus Features
… To understand the computation that transforms sensory encoding to decision choice, I next use visual adaptation as a tool to determine a decoder adopted by the mouse to discriminate orientation (target versus. distractor orientation) via a combination of in vivo calcium imaging and modeling …

Investigation of Dynamic Ultrasound Reception in Bat Biosonar Using a Biomimetic Pinna Model
… evolutionary success. They rely on parsimonious sensory inputs provided by echolocation, yet are able to master lives in complex environments. The outer ears (pinnae) of bats are intricately shaped receiver baffles that encode sensory information through a diffraction process. In some bat species …

Neuromast Optogenetics Reveals Rules of Spatial Encoding in the Zebrafish Lateral Line
… respond effectively to their environment, their sensory circuits must learn to distinguish between similar patterns of sensory information. A lingering question in neuroscience is how neuronal circuits achieve this performance. In this study, I use the posterior lateral line (pLL) of larval …

Growing synfire chains with triphasic spike-time-dependent plasticity
… of behaviours including motor responses and sensory encoding. There have been many previous computational studies which address the development of synfire chains. However, they have all required either initial sparse connectivity or strong topological constraints in addition to any synaptic …

Sensory representations optimized for the natural environment
… can impact and determine perceptual behavior and sensory representation in both biological and artificial systems. In Chapter 1, I provide a brief review of the theory of efficient coding, models of natural image statistics, and the interplay between these two fields. In Chapter 2, based on a …

On the High-Dimensional Geometry of Neuronal Population Dynamics
… behavioral variability. We found that the visual encoding of object size is robust at the population level, despite the highly variable activity of single neurons. This robustness despite variability was due to the multi-dimensional geometry of the neuronal population dynamics: trial-to-trial …
