Modelling Across Scales of Analysis
This lesson provides an overview of plasticity on many levels, including short-term, long-term, metaplasticity, and structural plasticity. The lesson also provides xamples related to modelling of biochemical networks.

This presentation assumes some familiarity with biochemical networks involved in synaptic plasticity and some knowledge of biochemical network modelling and simulation. Recommended: Cellular Mechanisms of Brain Function, especially lectures 13 on pre-synaptic plasticity and lectures 16-20 on post-synaptic plasticity.
