Detailed Description

Poisson neurons.

It has 1 state variable:

• timeStepToSpike - Number of timesteps to next spike

and 1 parameter:

• rate - Mean firing rate (Hz)

Note

Internally this samples from the exponential distribution using the C++ 11 <random> library on the CPU and by transforming the uniform distribution, generated using cuRAND, with a natural log on the GPU.

Member Function Documentation

getDerivedParams()

virtual DerivedParamVec NeuronModels::PoissonNew::getDerivedParams ( ) const

inlineoverridevirtual

Gets names of derived model parameters and the function objects to call to Calculate their value from a vector of model parameter values

Reimplemented from Snippet::Base.

getInstance()

static const NeuronModels::PoissonNew* NeuronModels::PoissonNew::getInstance ( )

inlinestatic

getParamNames()

virtual StringVec NeuronModels::PoissonNew::getParamNames ( ) const

inlineoverridevirtual

Gets names of of (independent) model parameters.

Reimplemented from Snippet::Base.

getSimCode()

virtual std::string NeuronModels::PoissonNew::getSimCode ( ) const

inlineoverridevirtual

Gets the code that defines the execution of one timestep of integration of the neuron model.

The code will refer to for the value of the variable with name "NN". It needs to refer to the predefined variable "ISYN", i.e. contain , if it is to receive input.

Reimplemented from NeuronModels::Base.

getThresholdConditionCode()

virtual std::string NeuronModels::PoissonNew::getThresholdConditionCode ( ) const

inlineoverridevirtual

Gets code which defines the condition for a true spike in the described neuron model.

This evaluates to a bool (e.g. "V > 20").

Reimplemented from NeuronModels::Base.

getVars()

virtual StringPairVec NeuronModels::PoissonNew::getVars ( ) const

inlineoverridevirtual

Gets names and types (as strings) of model variables.

Reimplemented from NewModels::Base.
