Detailed Documentation

Spike source array.

A neuron which reads spike times from a global spikes array It has 2 variables:

• startSpike - Index of the next spike in the global array
• endSpike - Index of the spike next to the last in the globel array

and 1 global parameter:

• spikeTimes - Array with all spike times

Methods

virtual std::string getSimCode() const

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.

virtual std::string getThresholdConditionCode() const

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

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

virtual std::string getResetCode() const

Gets code that defines the reset action taken after a spike occurred. This can be empty.

virtual VarVec getVars() const

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

virtual EGPVec getExtraGlobalParams() const

Gets names and types (as strings) of additional per-population parameters for the weight update model.
