Interconnectivity¶
-
class
connection
¶ Describes a connection between two cells, defined by source and destination end points (that is pre-synaptic and post-synaptic respectively), a connection weight and a delay time.
-
connection
(source, destination, weight, delay)¶ Construct a connection between the
source
and thedest
with aweight
anddelay
.
-
source
¶ The source end point of the connection (type:
arbor.cell_member
).
-
dest
¶ The destination end point of the connection (type:
arbor.cell_member
).
-
weight
¶ The weight delivered to the target synapse. The weight is dimensionless, and its interpretation is specific to the type of the synapse target. For example, the expsyn synapse interprets it as a conductance with units μS (micro-Siemens).
-
delay
¶ The delay time of the connection [ms]. Must be positive.
An example of a connection reads as follows:
import arbor # construct a connection between cells (0,0) and (1,0) with weight 0.01 and delay of 10 ms. src = arbor.cell_member(0,0) dest = arbor.cell_member(1,0) w = 0.01 d = 10 con = arbor.connection(src, dest, w, d)

class
gap_junction_connection
¶ Describes a gap junction between two gap junction sites. Gap junction sites are represented by
arbor.cell_member
.-
local
¶ The gap junction site: one half of the gap junction connection.
-
peer
¶ The gap junction site: other half of the gap junction connection.
-
ggap
¶ The gap junction conductance [μS].
