Combined role of seizure-induced dendritic morphology alterations and spine loss in newborn granule cells with mossy fiber sprouting on the hyperexcitability of a computer model of the dentate gyrus. [PDF]
PLoS Computational Biology, 2014 Temporal lobe epilepsy strongly affects hippocampal dentate gyrus granule cells morphology. These cells exhibit seizure-induced anatomical alterations including mossy fiber sprouting, changes in the apical and basal dendritic tree and suffer substantial ...

Early intervention combined with targeted treatment promotes cognitive and behavioral improvements in young children with fragile x syndrome. [PDF]
, 2012 Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability due to an expansion in the full mutation range (>200 CGG repeats) of the promoter region of the FMR1 gene leading to gene silencing.

Small, smaller… dendritic spine [PDF]
The EMBO Journal, 2014 Spines are highly motile protrusions emerging from the dendritic shafts of neurons. The dynamics of these post‐synaptic structures are ruled by actin filament turnover. However, our understanding of the mechanisms of actin polymerization in dendritic spines is quite ambiguous.

Reaction–Diffusion Model-Based Research on Formation Mechanism of Neuron Dendritic Spine Patterns
Frontiers in Neurorobotics, 2021 The pattern abnormalities of dendritic spine, tiny protrusions on neuron dendrites, have been found related to multiple nervous system diseases, such as Parkinson's disease and schizophrenia.

Dendritic cable with active spines: a modeling study in the spike-diffuse-spike framework [PDF]
, 2005 The spike-diffuse-spike (SDS) model describes a passive dendritic tree with active dendritic spines. Spine-head dynamics is modelled with a simple integrate-and-fire process, whilst communication between spines is mediated by the cable equation. Here we

Sleep deprivation causes memory deficits by negatively impacting neuronal connectivity in hippocampal area CA1 [PDF]
, 2016 Brief periods of sleep loss have long-lasting consequences such as impaired memory consolidation. Structural changes in synaptic connectivity have been proposed as a substrate of memory storage.

Signaling in dendritic spines and spine microdomains [PDF]
Current Opinion in Neurobiology, 2012 The specialized morphology of dendritic spines creates an isolated compartment that allows for localized biochemical signaling. Recent studies have revealed complexity in the function of the spine head as a signaling domain and indicate that (1) the spine is functionally subdivided into multiple independent microdomains and (2) not all biochemical ...
