I tried to modify the weight into negative How? but the effect is still excitatory So presumably the target is an artificial spiking cell, not a synaptic mechanism attached to a section. If this inference is correct, what kind of artificial spiking cell is the target, and what happens to its activa...

I tried to modify the weight into negative, but the effect is still excitatory

I built a network with 200 neurons in it. But with "Netcon", one cell can only trigger the connected cell to fire. Is there any way to make the connection "inhibitive" (build interneurons' function)?

Thanks

I've built a small network, trying to train it. Is that possible Yes. What learning rule do you have in mind? I don't whether NEURON is a dynamic or not? What do you mean by "dynamic"? Can Neuron support synaptic plasticity or changing the weight adaptively? If you can describe the rule f...

Can Neuron support synaptic plasticity or changing the weight adaptively?

You could just use as many IClamps as you need pulses. If the pulses are periodic, you could use one of the mechanisms defined by ipulse1.mod or ipulse2.mod (see periodic stimulation? http://www.neuron.yale.edu/phpBB/viewtopic.php?f=8&t=137). If they are completely arbitrary in duration and tim...

here is my stimulation:

neuron[0].soma {
stim = new IClamp(0.5)
stim.del = 5
stim.dur = 50
stim.amp = 1
}

I want the cell to receive stimulation two or more times, so how can I set the parameters to complete this?

Thank you!
