Transmitter types in Auryn determine on which neuronal or synaptic variable a synaptic event has an effect. The following types are currently implemented in auryn_definitions.h (see also the code of Connection):

• GLUT: target glutamatergic receptors at destination neuron
• GABA: target gabaergic receptors at destination neuron
• AMPA: target AMPA receptors only at receiving neuron
• NMDA: target NMDA receptors only at receiving neuron
• MEM: target the membrane voltage directly (for instance to implement current-based synapse models)
• CURSYN: target an auxiliary variable (see default StateVectors or g_cursyn) used to implement current-based synapses with dynamics (e.g. exponential currents in SIFGroup)
