Discrete and differentiated encoding of distinct components of spatial experience occurs within the proximodistal subfields of the dorsoventral axis of the hippocampus [PDF]

Frontiers in Behavioral Neuroscience
A multitude of studies have confirmed the essential role of the hippocampus in the acquisition and updating of associative experience. In rodents, spatial memories are dependent on hippocampal information processing and encoding.

Hippocampal-Medial Entorhinal Circuit Is Differently Organized Along the Dorsoventral Axis in Rodents

Cell Reports, 2023
Summary: 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.

Developmental system drift in dorsoventral patterning is linked to transitions to autonomous development in Annelida [PDF]

Nature Communications
The Bone Morphogenetic Protein (BMP) pathway is the ancestral signalling system patterning the dorsoventral axis in bilaterally symmetrical animals. However, in Spiralia, a large bilaterian clade including molluscs and annelids, BMP’s axial function ...

Modifying Factors of Adult Hippocampal Neurogenesis: A Dorsoventral Perspective in Health and Disease [PDF]

Cells
Adult hippocampal neurogenesis (AHN) is a dynamic process that sustains neural plasticity and contributes to cognition, emotion, and stress resilience. While its functional significance in humans remains debated, growing evidence suggests that AHN plays ...

Horizontal Boundary Cells, a Special Group of Somitic Cells, Play Crucial Roles in the Formation of Dorsoventral Compartments in Teleost Somite

Cell Reports, 2019
Summary: Establishment of robust gene expression boundary is crucial for creating elaborate morphology during development. However, mechanisms underlying boundary formation have been extensively studied only in a few model systems.

Transcriptome Reveals Multi Pigmentation Genes Affecting Dorsoventral Pattern in Avian Body

Frontiers in Cell and Developmental Biology, 2020
Certain animals exhibit a special dorsoventral pattern with a lighter ventral side compared to the dorsal one and this phenomenon was preserved in the long-term evolution process. Birds also retain this trait. Recently, Inaba et al.

Rescue of sharp wave-ripples and prevention of network hyperexcitability in the ventral but not the dorsal hippocampus of a rat model of fragile X syndrome

Frontiers in Cellular Neuroscience, 2023
Fragile X syndrome (FXS) is a genetic neurodevelopmental disorder characterized by intellectual disability and is related to autism. FXS is caused by mutations of the fragile X messenger ribonucleoprotein 1 gene (Fmr1) and is associated with alterations ...

Deep learning-based feature extraction for prediction and interpretation of sharp-wave ripples in the rodent hippocampus

eLife, 2022
Local field potential (LFP) deflections and oscillations define hippocampal sharp-wave ripples (SWRs), one of the most synchronous events of the brain.

Increased Inhibition May Contribute to Maintaining Normal Network Function in the Ventral Hippocampus of a Fmr1-Targeted Transgenic Rat Model of Fragile X Syndrome

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,

The asymmetric photosynthetic characteristics of the isobilateral sorghum leaves under the illumination of the diffuse light

Frontiers in Plant Science, 2023
The difference between photosynthesis on the two leaf sides (dorsoventral asymmetry) of photosynthesis is important for light-use patterns, but the asymmetry is environment dependent.
