Genetic control of organ shape and tissue polarity.
PLoS Biology, 2010 The mechanisms by which genes control organ shape are poorly understood. In principle, genes may control shape by modifying local rates and/or orientations of deformation.

How entorhinal grid cells may learn multiple spatial scales from a dorsoventral gradient of cell response rates in a self-organizing map. [PDF]
PLoS Computational Biology, 2012 Place cells in the hippocampus of higher mammals are critical for spatial navigation. Recent modeling clarifies how this may be achieved by how grid cells in the medial entorhinal cortex (MEC) input to place cells.

MCN1 neurite size differs across the dorsoventral axis.
, 2015 (A) Volume rendering of MCN1 soma (filled arrow) and smaller neurites (bracket) in the most dorsal portion of the neurite arborization (volume rendering of z-stack: 46 optical slices, 1.0 μm interval). (B) Thicker neurite branches (open arrowheads) occur

Dorsoventral Differences in Intrinsic Properties in Developing CA1 Pyramidal Cells [PDF]
, 2012 The dorsoventral and developmental gradients of entorhinal layer II cell grid properties correlate with their resonance properties and with their hyperpolarization-activated cyclic nucleotide-gated (HCN) ion channel current characteristics.

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.

Xmab21l3 mediates dorsoventral patterning in Xenopus laevis
Mechanisms of Development, 2012 Specification of the dorsoventral (DV) axis is critical for the subsequent differentiation of regional fate in the primary germ layers of the vertebrate embryo. We have identified a novel factor that is essential for dorsal development in embryos of the frog Xenopus laevis.

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical Record, EarlyView.Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

The Anatomical Record, EarlyView.Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.
