Spreading depolarization is followed by seizure-like activation of the hippocampus: potential mechanism of migraine-aura triggered seizures [PDF]

The Journal of Headache and Pain
Background Propagation of spreading depolarization (SD), a wave of transient cellular depolarization, over the cerebral cortex drives migraine aura symptoms.

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.

Dorsoventral patterning in plants [PDF]

Genes & Development, 1999
Although mutations affecting dorsoventral patterning in plants have been known for centuries (Linnaeus 1749), the underlying mechanisms controlling this process have remained mysterious. Recent papers by Sawa et al. (1999b) and others have begun to shed light on this subject through the isolation and characterization of genes responsible for ...

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,

Understanding Dorsoventral Topography [PDF]

Neuron, 2002
Retinal axons project to their central targets along two orthogonal topographic axes, anterior-posterior (A-P) and dorsal-ventral (D-V). While ephrin-A/EphA signaling determines A-P topography, little has been known about the molecular mechanisms guiding axons along the D-V axis. Two papers by Mann et al. and Hindges et al.

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.

Generation of dorsoventral human spinal cord organoids via functionalizing composite scaffold for drug testing

iScience, 2023
Summary: The spinal cord possesses highly complex, finely organized cytoarchitecture guided by two dorsoventral morphogenic organizing centers. Thus, generation of human spinal cord tissue in vitro is challenging. Here, we demonstrated a novel method for
