Connecting components¶
Connecting sections¶
To other sections¶
Connecting sections together is the basic way of constructing cells in NEURON. You can
do so using the Section.connect
method.
Patch
from patch import p
s = p.Section()
s2 = p.Section()
s.connect(s2)
NEURON
from neuron import h
s = h.Section()
s2 = h.Section()
s.connect(s2)
Network connections¶

In parallel simulations¶
In Patch most of the parallel context is managed for you, and you can use the
interpreter.PythonHocInterpreter.ParallelCon()
method to either connect an
output (cell soma, axons, …) to a GID or a GID to an input (synapse on postsynaptic
cell, …)
Patch
Detecting the spikes of a Section and connecting them to GID 1:
from patch import p
gid = 1
s = p.Section()
nc = p.ParallelCon(s, gid)
Connecting the spikes of GID 1 to a synapse:
from patch import p
gid = 1
syn = p.Section().synapse(p.SynExp)
nc = p.ParallelCon(gid, syn)
NEURON
Detecting the spikes of a Section and connecting them to GID 1:
from neuron import h
gid = 1
h.nrnmpi_init()
pc = h.ParallelContext()
s = h.Section()
nc = h.NetCon(s(0.5)._ref_v, None)
pc.set_gid2node(gid, pc.id())
pc.cell(gid, nc)
pc.outputcell(gid)
Connecting the spikes of GID 1 to a synapse:
from neuron import h
gid = 1
h.nrnmpi_init()
pc = h.ParallelContext()
s = h.Section()
syn = h.SynExp(s)
pc.gid_connect(gid, syn)
