Some principles of somatosensory cortical organization in rats and humans
… research elucidated principles of somatosensory cortical al organization at the level of the receptive field, cortical map, and cortical area in the rat and human. throughout these studies, a central focus was on the connection between each level of organization and the capacity for cortical …

Interrogating the infant mind with fMRI
… research focused on uncovering the functional organization of higher-level perceptual and cognitive processes in infants’ brains. For two decades scientists have attempted to use functional magnetic resonance imaging (fMRI) to study infant perceptual and cognitive function. However, it remains …

Anatomical Bases for Auditory Projections to Suprasylvian Visual Areas in the Cat Cerebral Cortex
… from one to another is an unexplored issue of cortical organization. The present experiments addressed this problem by examining auditory projections to the lateral suprasylvian visual area (LSS) of the cat using neuroanatomical tract tracing methods. Injections of tracer (Biotinylated Dextran …

Neural computation of depth from binocular disparity
… humans, we revealed systematic and reproducible cortical organization for stereoscopic depth in dorsal visual areas V3A and V3B/KO. Within these regions, depth selectivity was inversely related to depth magnitude — a key characteristic of stereoscopic perception. Finally, we report evidence for a …

Abnormal cell patterning at the cortical gray-white matter boundary in autism spectrum disorders
… research on neuronal spacing and columnar organization indicates the presence of cell patterning alterations within the cerebral cortex of individuals with autism spectrum disorders (ASD). These patterning abnormalities include irregularities at the gray-white matter boundary and may …

Sex differences in the cortex of the rat: The cellular basis
… rats at 90 days of age. Sex differences in cortical size were found to be widespread across the cortical mantle; however, the expression of sex differences was specific to region and lamina. Asymmetries in cortical thickness were found in a few areas but did not vary with the sex. The …

Effects of Temporal and Spatial Context Within the Macaque Face-Processing System
… machinery, and if so, what that machinery's organization might be. To address these questions, we monitored the brain activity of macaque monkeys while they viewed low- and high-level motion and form stimuli. We found that, beyond classical motion areas and the known face patch system, moving …

Normalization Among Heterogeneous Population Confers Stimulus Discriminability on the Macaque Face Patch Neurons
… discriminability by virtue of the modularity of cortical organization, heterogeneity within the population, and systematicity of the neural response.</p>

Exploring the functional organization of cerebral cortex using data from the Human Connectome Project
… a non-invasive window to look at the macroscale organization of cerebral cortex. Despite monumental efforts to map the structure and function of cerebral cortex, our understanding has been limited due to insufficient sample sizes, low-resolution imaging, and suboptimal volume-based analyses. In …

Modeling Cognition by Pruning and Topography-Learning in Deep Neural Networks
… we study the capability of capturing cortical organization, and the computational properties of topographic regularizers that encourage correlated representations. This part includes two studies. In Study 2.1, we evaluate whether a current leading state-of-the-art topographic model can …

The Long-Term Teratogenic Effect of Prenatal Alcohol Exposure on the Somatosensory and Motor Cortex of Rats
… components of the sensorimotor system are the cortical input to layer IV primary sensory cortex (SI) and output from layers V and VI primary motor cortex (MI). Therefore, the focus of this dissertation is on PAE-related anatomical and physiological deficits in SI and MI that are likely to play …
