Re: strange section count result

Thanks for the reply. I know this isn't correct because in geometry file I have this two lines of code "create dendrite[109]" and" create user5[77]". So I should have 196 sections in total. Creating only one neuron and using this piece of code I can get the correct index. index = 0 forsec "dendrite"...

strange section count result

Hello there, Using a "Hippo" template, I generated two cells "Hippos ". "dendrite" and "user5" are declared public in the template and I know that each cell has 196 sections. Now I want to group dendrite and user5 of each cell separately into two references "dend1", "dend2" and also count sections f...

Re: Driving synaptic event using vecStim

Hello,

I have a general question on VecStim() and hope this is the right place to post it. Using "new VecStim()" brings up this error "VecStim is not a template". I tested this on several machines and all give me the same error. What I'm doing wrong?

Thanks for your help,

Re: Activating a synapse at recorded or precomputed times

Thank you so much for the thorough answer. Here I pasted a part of the code in the case someone need it and/or for you to check it. However, I got this error saying " if arg 1 is an object it must be a point process or NULLObject". Can you help me on this? Thanks, BEGINSECTION= 0 ENDSECTION= TOTALDE...

Hi Ted, I have a question related to this post Driving a synapse with recorded or precomputed spike events https://www.neuron.yale.edu/phpBB/viewtopic.php?f=28&t=2117 I have 1000 vectors of event time and I want to apply these synapses to 1000 selected points on a dendritic tree. In a for loop I sel...
