accessing "low-level" parameters from the Channel

[Brad]

Is it possible to access from hoc the "low-level" parameters in the Channel Builder? For example, when using a channel model with a HH-style scheme, is there a way to reference A, k, and d from

Code: Select all

A*x/(1 - exp(-x)) where x = k*(v - d)

or

Code: Select all

A*exp(k*(v-d))

etc, for each of the gating variables?

I want to construct a channel whose activation v_half and slope varies with location. The most apparent thing to me would be to manipulate the parameter values for alpha_m and beta_m in a forall/for(x) construct, but I haven't found documentation that suggests how to do this. I've looked through some session files, but nothing jumps out at me as the answer.

You need to enable, and exploit, the ChannelBuilder's "aliases" feature.

Thanks for the quick reply, Ted. That looks like exactly what I need. I scanned through most of the posts in the "Adding new mechs..." forum category. I must not have thought "nsingle" (the title of that particular post) was relevant to my topic, and I didn't know to search for "alisases."
