Re: Programming Long-Term Potentiation

Hi Ted. I incorporated the hebbian plasticity mod file that is represented with STDP into my model. I also read Bi and Poo's 2001 paper on Synaptic Modification by Correlated Activity so that I could understand how the mechanism in this mod file should behave. I am still not observing LTP as I am ex...

Re: Programming Long-Term Potentiation

Thank you Ted. Chapter 10 was very helpful. I used the event-driven mechanism that has stream-specific saturation and got the AMPA point process to work, however, I am not seeing the LTP behavior that I was expecting. I set the transmitter duration to 50ms. I fired neuron 1 at neuron 3 at t = 1000ms...

Programming Long-Term Potentiation

Using hoc, I created a network of neurons to represent a reward circuit. Each soma has a dendrite and an axon. I included biologically realistic diameters and lengths from http://www.neuromorph.org . I also used mammalian equilibirum potential values from http://www.anc.ed.ac.uk/school/neuron/tutori...

Cell behavior driven by "if" statements

I created 3 neurons (Neuron_1, Neuron_2 and Neuron_3). When Neuron_1 is stimulated with an IClamp, Neuron_1 depolarizes Neuron_2. When Neuron_3 is stimulated with an IClamp, Neuron_3 also depolarizes Neuron_2. I am trying to create the following conditional statement: If Neuron_1 fires at Neuron_2, ...

Connecting 2 neurons

Hello, I am new to programming on Neuron. I am trying to create 2 neurons (each with 1 soma, 1 dendrite and 1 axon). I connected axon1 with dend2 and then I connected axon2 with dend1. I also put an IClamp to stimulate soma1. I am expecting that initial stimulation to produce a continuous closed-loo...
