A link between ECM plasticity and synaptic morphological evolution

TL;DR

This paper explores how the plasticity of the extracellular matrix, particularly collagen's mechanical properties, influences synaptic morphological changes following excitation, linking cellular mechanics to neural plasticity.

Contribution

It establishes a novel connection between ECM plasticity and synaptic morphological evolution, integrating mechanical properties with neural plasticity theories.

Findings

ECM plasticity affects synaptic morphology

Collagen's mechanical properties influence synaptic changes

Links between ECM dynamics and neural plasticity are proposed

Abstract

We made a link between Extra Cellular Matrix (ECM) plasticity and the morphologi cal changes in synapses after synaptic excitation. A recent study by Zhang et al \cite{zhang} showed tha t transmembrane voltage causes movement of the cell membrane. Here we will study the relation between th e mechanical properties of collagen which is the major component of the ECM and synaptic morphological c hanges in relation with the theory of DO Hebb \cite{hebb}
