Re: Implementing extracellular stimulation

Hi Ted, back with more questions. I got the stimuli code to work pretty well on a simple model and working to size it up. On top of that, I am trying to find positions of each sections relative to the soma so that I can know their relative (x,y,z) position to a point source with known distance (x,y,...

Re: Implementing extracellular stimulation

Here is a sketch of what I meant by single point of stimuli in a segment: https://imgur.com/tU9v8sB I believe what we meant as a "bolus" is that single point of voltages is on/off for a specific period of time as if it was clamped (VClamp at that middle point) (I think this is the right te...

Re: Implementing extracellular stimulation

From further discussions and coding, we have concluded that we want (for now) a singular point where the voltage is in each segment as our wave form as a bolus (in the future a time varying voltage will be implemented). We have values that we want to apply to the middle of x,y,z coordinates (i.e. ce...

Re: Implementing extracellular stimulation

I talked to my PI and the lambda rule is what we'll progress forward with. Makes more sense to use something already widely accepted. the range values that correspond to segment midpoints are available as a simple function call at any time--no need to calculate and store those values in advance. Sec...

Re: Extracellular stimulation and recording

Apologies for the double post, tried to edit and messed it up. Thank you for your response. By "put in an electrode", I meant apply an extracellular stimulus. The reason for trying to get a different segment division of the model due to the amount of voltage values I would be inputing into...

Re: Extracellular stimulation and recording

Hi, I am working on a code where I extract small compartments of a model cell and put in an electrode (could be an IClamp? unsure about it) in each of the compartment. i am struggling with the implementing aspect of it (doing so with an arbitary value to get syntax before putting realistic values in...

Re: Extracellular stimulation and recording

I think by grid I meant that I have a matrix of voltage values that I already know from a specific simulation that I run. The values come out of multiple electrodes and seeing what is the minimum voltage for activation is in that specific area therefore with all the possible outputs forming some sor...

Implementing extracellular stimulation

(In response to Extracellular stimulation and recording https://www.neuron.yale.edu/phpBB/viewtopic.php?t=168) my step of the project is to have that extracellular stimulation as a grid superposed on the model Not sure what you mean by this. Do you mean that you know the values of extracellular pote...
