The data is a binary white noise signal whose power spectrum rolls of at 2hz. I have got that program in a hoc file and stored the data in a vector.

synaptic input

Hii, I have a set of data which is my input, in a vector and i want to connect it to the cell through a synapse. I have my vector say v3 in a hoc file named say input.hoc Now i want to give the data from the vector v3 as an input to the cell through the synapse in the other hoc file say main.hoc. I ...

If its not a problem can you also tell me how we can get a mechanism to get the copy of the membrane potential( just curious and may be that can help me)

Thank you

Sorry if i am not clear. I wanna record the time elapsed for the voltage level to reach from the -70mV level to -30mV level for a single duty cycle(My input is a sinusoidal signal of frquency 2hz for about 30sec). It may cross the -30mV level to spike in that duty cycle or it may not. I wanna note t...

I used the 2 thresholds for the same source of the netcon events as in the code below as per the suggestions you made. This is making the 2nd threshold to override the first one. I can say this because when i saw the values in the t0, it is always zero. Is it because i am using the same source in th...

If i am not wrong by using the 2 thresholds the output may change and i may not get any threshold crossing for the -30mV level I tried it in the following code(a part from the main code) of mine where i am to measure the times in the newcell[1] at both the -30mV and -70mV levels. From those times i ...

finding time at instantaneous voltage level

Hii, I am trying to record the times at a particular voltage level say -70mV and also at an another voltage level of say -30mV for a particular cell output. If i am right the netcon class record records only the spike timings not the time at a paticular instant of voltage. Sorry if i got that wrong....

Thank you for your reply. This helps.
But i am curious though is there any way to just output the data in a format
which i can use in other programs, as i mentioned the way i did it did not work well.

Thanks

Thank you for the prompt reply. I tried capturing the spike timings using the vector classes record and to bin my spikes i used the spikebin command. well i dint yet get the psth graph as of now. So i am trying to import my spike timings to a seperate program, first by capturing the data into a file...

Hii

I am also trying to get a Peri stimulus time histogram for the output i have got with the trigger being my time of the input where the signal rises above a particular level (My input signal is a sine wave ). Is there a particular method in order to do it.

calculation

Hello, I just had few questions. I have to run the simulation for a long time for around 3min, but the problem is it was taking too long for the entire simulation to be completed by standard run tool.So i have used the variable step control and run the simulation which helped in speeding up the simu...

net_send and net_receive

Hello I am new to this forum as well as the neuron software and i had a question regarding the net_send and net_receive blocks, llike how does these blocks actually work in neuron software. I want to use it for making a pulse train for my input to the neuron. If anybody could help me out in this reg...
