Plasticity Dynamics Improves Reservoir Performance on Mixed-Timescale Memory Tasks

This paper introduces synaptic plasticity into recurrent networks to improve their ability to process mixed-timescale signals by enabling simultaneous handling of fast and slow components.

Geometry-based dynamics of the postsynaptic density explain protein capture by an actin-spine-geometry-dependent synaptic tag

The paper models how actin and spine geometry influence synaptic tagging and capture, showing that PSD remodeling and curvature-mediated PRP recruitment underlie late-phase potentiation.

The synaptic tag as an emergent biophysical state depending on the synaptic actin dynamics and the postsynaptic density

The paper develops a computational model linking synaptic actin dynamics and postsynaptic density size to the synaptic tag hypothesis, explaining experimental findings and predicting nonlinear plasticity accumulation.

Stable Actin As Synaptic Tag

The paper investigates whether actin dynamics and spine geometry can serve as a synaptic tag for long-term potentiation (LTP) by combining mathematical modeling and FRAP experiments.

Modeling the shape of synaptic spines by their actin dynamics

The paper develops a biophysical model to link actin dynamics to synaptic spine shape fluctuations, showing that discrete polymerization foci drive membrane changes.
