PyNN 0.9.1 release notes¶
May 4th 2017
Welcome to PyNN 0.9.1!
Stochastic synapses¶
This release adds three new standard synapse models, available for the NEST and NEURON simulators. They are:
SimpleStochasticSynapse
- each spike is transmitted with a probability p.StochasticTsodyksMarkramSynapse
- synapse exhibiting facilitation and depression, implemented using the modelof Tsodyks, Markram et al., in its stochastic version.
MultiQuantalSynapse
- synapse exhibiting facilitation and depression with multiple quantal release sites.
There are some new example scripts which demonstrate use of the synapse models - see Example of simple stochastic synapses and Example of facilitating and depressing synapses in deterministic and stochastic versions.
Note that the new models require building a NEST extension; this is done automatically during installation (when running pip install or setup.py install).
Bug fixes¶
A number of bugs have been fixed.
