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 model

    of 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.
