PyNN 0.9.2 release notes¶
November 22nd 2017
Welcome to PyNN 0.9.2!
Recording injected currents¶
It is now possible to record the injected current from CurrentSource
objects in PyNN, for example:
noise = sim.NoisyCurrentSource(mean=0.5, stdev=0.2, start=50.0, stop=450.0, dt=1.0)
noise.record()
sim.run(500.0)
signal = noise.get_data()
The returned signal object is a Neo AnalogSignal
.
Python 2.6¶
As of this version, PyNN no longer supports Python 2.6.
NEST 2.14.0 and NEURON 7.5¶
PyNN 0.9.1 now supports the latest versions of NEST and NEURON. NEURON 7.4 is also still supported. NEST 2.12.0 should still work in most circumstances, but current recording (see above) requires a more recent version.
native_electrode_type¶
It has been possible for some time to use native (NEST-specific) neuron and synapse models with pyNN.nest
.
It is now also possible to use native current generator models, e.g.:
noise = sim.native_electrode_type('noise_generator')(mean=500.0, std=200.0, start=50.0,
stop=450.0, dt=1.0)
Bug fixes¶
A number of bugs have been fixed.
