如何在 NEURON 中创建突触？

Question

How can I create a synapse in the NEURON simulator using its Python interface? I would like to create 2 Sections and connect them with a synapse, but there aren't any functions for it on the Section API or in the Section docs :

from neuron import h

src = h.Section(name="source")
dest = h.Section(name="destination")

Answer 1

In NEURON synapses are of the family of PointProcess es . You can insert a PointProcess into a Section by accessing it on the HocInterpreter and giving it a Segment on the Section . You then have to create a NetCon from a voltage pointer on the presynaptic Section ( src(x)._ref_v ) to the target point process:

from neuron import h

dest = h.Section(name="destination")
synapse = h.ExpSyn(sec(0.5))
src = h.Section(name="source")
connection = h.NetCon(src(0.5)._ref_v, synapse)
