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.

Physical Mechanisms Shaping the Drosophila Dorsoventral Compartment Boundary [PDF]
Current Biology, 2012 Separating cells with distinct identities and fates by straight and sharp compartment boundaries is important for growth and pattern formation during animal development. The physical mechanisms shaping compartment boundaries, however, are not fully understood.We combine theory and quantitative experiments to investigate the roles of different ...

Calcium mediates dorsoventral patterning of mesoderm in Xenopus [PDF]
Current Biology, 2001 Calcium signals participate in the differentiation of electrically excitable and nonexcitable cells; one example of this differentiation is the acquisition of mature neuronal phenotypes. For example, transient elevations of the intracellular calcium concentration have been recorded in the ectoderm of early embryos, and this elevation has been proposed ...

Full transcriptome analysis of early dorsoventral patterning in zebrafish.
PLoS ONE, 2013 Understanding the molecular interactions that lead to the establishment of the major body axes during embryogenesis is one of the main goals of developmental biology. Although the past two decades have revolutionized our knowledge about the genetic basis

A role for neural determination genes in specifying the dorsoventral identity of telencephalic neurons [PDF]
Genes & Development, 2000 Neurogenin1 (Ngn1), Neurogenin2 (Ngn2), and Mash1 encode bHLH transcription factors with neuronal determination functions. In the telencephalon, the Ngns and Mash1 are expressed at high levels in complementary dorsal and ventral domains, respectively. We

Dorsoventral Patterning: A Serpin Pinned down at Last [PDF]
Current Biology, 2004 Dorsoventral patterning in Drosophila has long been known to involve a cascade of proteases, held in the inactive zymogen state prior to signaling. At long last, the prediction that a protease inhibitor is involved in this pathway has been shown to be true, with the identification of a serpin that plays a key part in Drosophila embryonic patterning.

Brain Sciences, 2023 A common neurobiological mechanism in several neurodevelopmental disorders, including fragile X syndrome (FXS), is alterations in the balance between excitation and inhibition in the brain. It is thought that in the hippocampus, as in other brain regions,

bioRxiv, 2022 The general understanding of hippocampal circuits is that the hippocampus and the entorhinal cortex (EC) are topographically connected through parallel identical circuits along the dorsoventral axis. Our anterograde tracing and in vitro electrophysiology

Wireless closed-loop optogenetics across the entire dorsoventral spinal cord in mice
Nature Biotechnology, 2021 Optoelectronic systems can exert precise control over targeted neurons and pathways throughout the brain in untethered animals, but similar technologies for the spinal cord are not well established.
