Increased spine PIP3 is sequestered from dendritic shafts
Molecular Brain, 2022 Phosphatidylinositol 3,4,5-trisphosphate (PIP3) is a lipid second messenger that is crucial for the synaptic plasticity underlying learning and memory in pyramidal neurons in the brain. Our previous study uncovered PIP3 enrichment in the dendritic spines

SpineTool is an open-source software for analysis of morphology of dendritic spines
Scientific Reports, 2023 Dendritic spines form most excitatory synaptic inputs in neurons and these spines are altered in many neurodevelopmental and neurodegenerative disorders.

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

Spiny and Non-spiny Parvalbumin-Positive Hippocampal Interneurons Show Different Plastic Properties
Cell Reports, 2019 Summary: Dendritic spines control synaptic transmission and plasticity by augmenting post-synaptic potentials and providing biochemical compartmentalization.

Modeling Maintenance of Long-Term Potentiation in Clustered Synapses, Long-Term Memory Without Bistability [PDF]
, 2015 Memories are stored, at least partly, as patterns of strong synapses. Given molecular turnover, how can synapses maintain strong for the years that memories can persist?

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.

Hippocampal structural plasticity accompanies the resulting contextual fear memory following stress and fear conditioning [PDF]
, 2013 The present research investigated the resulting contextual fear memory and structural plasticity changes in the dorsal hippocampus (DH) following stress and fear conditioning. This combination enhanced fear retention and increased the number of total and
