Modelling Across Scales of Analysis

Difficulty level

This lesson discuses forms of neural plasticity on many levels, including short-term, long-term, metaplasticity, and structural plasticity. During the lesson you will also be presented with examples related to the modelling of biochemical networks. 

Topics covered in this lesson
  • Forms of plasticity. Is memory the same as synaptic plasticity? Hebb rule.
  • Pavlovian (classical) conditioning.
  • NMDA receptor role in associativity.
  • Synaptic weight/strength.
  • Network computation.
  • Associative memory.
  • Pattern recognition and completion.
  • Feedback and bistability.
  • Plasticity dependent on input patterns.
  • Equation for synaptic weight.
  • Facilitation/depression.
  • Dendritic protein synthesis.
  • Bistability. Metaplasticity.

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.
