Excitatory and inhibitory STDP cooperatively shape structured lateral connections | To test this idea, we introduced STDP-type synaptic plasticity in lateral excitatory connections and feedback inhibitory connections and investigated how different STDP rules cause different structures in the circuit. |
Model | We first studied synaptic plasticity at the feed-forward connections (connections from the input layer to the output layer), while fixing lateral connections (i.e., connections from the output layer to the lateral layer and connections from the lateral layer to the output layer). |
Model | Synaptic plasticity . |
Model | For most of this study, we focused on synaptic plasticity in the feedfor-ward connection WX, with fixed lateral synaptic weights WY and W2. |
