Encoding Voxels with Deep Learning
We review a recent paper that uses activations in deep neural networks to predict voxel activations during an object viewing task, discussing encoding, decoding, and future directions for both.

[draft] Interhemispheric connectivity endures across species: an allometric expose on the corpus callosum
We show that interhemispheric connectivity is crucial, independent of brain size, by better estimating within- and across-hemisphere connectivity, and factoring in that interhemispheric connectivity is mostly homotopic, regardless of brain size.

Stable long-range interhemispheric coordination is supported by direct anatomical projections
We analyze resting state and anatomical connectivity in a human and macaque brain, and show that the most stable connections in the resting state data correlate with the presence of direct anatomical connections.

Patchy Connectivity and Visual Processing Asymmetries: A Neuro-developmental Hypothesis
In this paper, we summarize our neural network modeling of left/right hemisphere differences in visual processing and how it emerges developmentally.

A Developmental Model of Hemispheric Asymmetries of Spatial Frequencies
Our paper showing that left/right hemisphere differences in visual processing can be explained by the development of long-range lateral connections when left/right hemisphere begin maturing at different times.

Hemispheric asymmetry in perception: A differential encoding account
Our journal publication showing how our model accounts for spatial frequency differences and data from the classic Sergent local/global differences between left/right visual fields.

Ph.D Dissertation: A unified hypothesis of visual asymmetry, interhemispheric communication, and their typical development in humans
Left and right hemispheres process visual information differently. Here I present computational modeling to suggest that the major difference is in shape and contour processing, and interhemispheric connectivity must not be ignored.

Uniquely human developmental timing may drive cerebral lateralization and interhemispheric coupling
Our paper showing that delays in transfer between the hemispheres cannot be as severe as typically stated. We also show that unreliability in delay can lead to decreased communication, and is likely present during development.

Connectivity asymmetry can explain visual hemispheric asymmetries in local/global, face, and spatial frequency processing
My first conference paper, showing that our computational model of long-range lateral connections can account for many types of left/right differences in visual processing.
