Short Term Plastic Synapses
- We're going to do some exploration of short term plastic synapses.
Get lab6.py or the
text version .
- Run it and print out the output spikes.
- Now, at step 3 in the code, comment in the projection, but make
sure to comment out the projection above.
- 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.
- Is this STP or STD?
- How long does it take to revert back to the original weight?
- Can you change the parameters to make it STP?
- Can you change the parameters to make it revert more quickly?
- If the firing weight is 0.1 the post synaptic neuron never fires.
Why?
- Can you change the parameters to allow it to fire?
