A projection causing direct conductance changes in the post-synaptic population.
Like the spiking projections, the connectivity may be one-one, one-all or random. In the latter case, the probability of any tow items being connected should be specified as p_connect.
Conductance projections may be made between any vector provider, including a population of cells, and a population of components able to receive conductance inputs. There are therefore two possible sorts of inputs: vectors which represent membrane potential, and vectors which are dimensionless, typically ranging between zero and one. For the latter type, the rescale flag should be set. This causes vector elements which are zero to add a conductance G0 with reversal potential V0 to the receiving component. Elements of value one give conductance and potential G1 and V1 and other values are scaled linearly.
One common use of this is to stimulate a population of cells with binary vectors. In this case, G0 might be zero, making V0 irrelevant. Non-zero elements of the vector would then open a conductance G1 at reversal potential V1.
