Spike Timing Dependent Plasticity

• There is some pretty solid evidence for Spike Timing Dependent Plasticity (STDP).
• The idea is if the pre-synaptic neuron fires before the post-synaptic neuron, the weight goes up.
• If the post-synaptic neuron fires first it goes down.
• The closer to firing simultaneously, the more the change.
• 
• There are also a lot of simulations using a lot of variants of this rule.
• Some of the work is in machine learning.
• PyNN and Nest have several rules.
