Sorry that I didn´t mention that. For the weight of the synapses I varied the value of course. I tried following weights: weight = 0.7 weight = 0.9 weight = 10 weight = 100 Now the last two values may be unrealistic but It was on purpose. I think the there exists synapses resp. there is connectivity...

Hello, Iḿ working on a network model of cells of one template. Each cell is connected by gaps and synapses. Then a part of the cells will be stimulated in order to make the whole network firing synchronously. The way of connecting with synapses is shown in the code above: nZellen = 100 // number of ...

Hello, I've got a question setting random numbers. If I use s.th. like this startcell = int(r.uniform(0,100)) This code is inside a for loop so it selects as many random numbers as I want the for loop to do. Is there a possibility the set the first random number of the random number generation proce...

Hello Ted, there is another question. My stim is now Ihw.. is there a possibility to change the amp but of course keeping the frequency? When i use an IClamp I can use this: nStimuli= 3 // would give me three stim nStim = 30 // would stimulate 30 cells each three times Frequenz = 80 // Hz T=(1/Frequ...

Thanks Ted for your quick response.

I plan to do this many times. That´s why I don´t want to click so much in the Print & File Manager Window on Select -> Move -> Print -> and so on.

Hello Ted, i wanted to ask if it is possible to write s.th. in my .hoc file so that the graphs that will be plotted, while the hoc file runs, will be saved automatically. i mean I know that I can save data from the run like explained in the Tutorial: http://www.anc.ed.ac.uk/school/neuron/ But is the...

To explain my problem , I think it`s better to post this here. [Moderator's comment: This thread started as a post to a different thread that addressed a very different topic. It was split off into a new thread for the sake of clarity, which is ill served if each thread is free to wander all over co...

In my hoc file I managed to write a .dat file to save the Information. Everything worked when I runned the hoc-file. After three runs with different frequencies, I runned it again with higher frequency. schreibe_dat() // is the proc to write the dat and worked The terminal said: /Applications/NEURON...

Hello,

if I want to plot voltage over time, I select Neuron Main Menu -> Graph-> Voltage axis and there pops up a window. V: -80 mV to +40 mV t: 0s to tstop.

Is there a easy way to change the limits of the y-Axis. V: -120 mV to +40 mV e.g..

Thank you again. Now there is one more thing... I want to use a control variable j. j is the number of stimuli or the peaks of current. Therefore I need Pi π to do s.th. like this.... dur = 200 // Duration of Stimulation (ms) Frequenz= 30 // frequency (Hz) f= Frequenz*(2*???Pi???) // frequency (radi...

Hello, I have following problem. I have an kalium.mod file (I use Mac OS X Lion): TITLE ich versuch mich mal...

Thanks again, it´s checked now... Is it possible to change the gap between two pulses of ihw? Like in the example i can change the distance between two square pulses by adding s.th. to the delay and multiplying it with the control variable j: for j = 0, nStimuli-1 { for i = 0, nStim-1 Zellen[i].soma...

Hello Ted,

thank you very much for responding that early. I thought I would get an email whenever someone answers so I´m late. I will try it.

Hello, I have a working network of 500 cells. I want to test synchrony of firing in the network. For that I want to stimulate about 20 % (100 cells) ore more to test the network. I already can do this by putting an IClamp on a random chosen cells, stimulating with a square pulse (see example above)....
