Table 1 Summary of code slots available in GeNN for user-defined models

Neuron

simCode

Main time step update of the neuron dynamics

thresholdConditionCode

A Boolean expression defining when spikes occur, checked every time step

resetCode

The code that defines a change in neuron variables, employed when a spike occurs

Synapse

simCode

Code that describes the synapse update after a pre-synaptic spike

simCodeEvnt

Code that describes the synapse update after a pre-synaptic spike event

simLearnPost

Code for the synaptic update triggered by a post-synaptic spike

eventThreshold

A Boolean expression that defines synaptic events

synapseDynamics

Update code for internal synapse dynamics applied every time step independent of spiking

Post-Synapse

postSyntoCurrent

Code that describes the transformation of synaptic variables into a post-synaptic current

postSynDecay

Code that describes the shared dynamics of summed synaptic activation, typically decay
