Short Term Plastic Synapses

  1. We're going to do some exploration of short term plastic synapses. Get lab6.py or the text version .
  2. Run it and print out the output spikes.
  3. Now, at step 3 in the code, comment in the projection, but make sure to comment out the projection above.
  4. What changing the comment does is switch from a static synapse to a plastic one. Notice how there is now only one spike instead of 4.
  5. Is this STP or STD?
  6. How long does it take to revert back to the original weight?
  7. Can you change the parameters to make it STP?
  8. Can you change the parameters to make it revert more quickly?
  9. If the firing weight is 0.1 the post synaptic neuron never fires. Why?
  10. Can you change the parameters to allow it to fire?
