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 the dest with a weight and delay.

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].
