Inhibitory control of plasticity promotes stability and competitive learning in recurrent networks
Patricia Rubisch & Matthias Hennig · COSYNE 2023
Current voltage-dependent plasticity models assume that any plastic event needs a postsynaptic action potential and use induction mechanisms that are insensitive to postsynaptic voltage fluctuations. However, experiments have demonstrated that inhibitory inputs can affect plasticity updates, likely through voltage-dependent effects. To address such findings, here we introduce the novel Voltage-Dependent Pathway model (VDP) where the induction variables track the membrane potential, increasing its sensitivity to fast fluctuations. We first confirm that this model produces spike-timing dependent
