Optical extracellular stimulation and xtra
Posted: Tue Mar 29, 2016 2:51 am
Hello,
I've been recently going through the implementation of ostim.mod from https://senselab.med.yale.edu/modeldb/s ... /ostim.mod and as such have also been learning about extracellular stimulation from older posts on the forum and the extracellular_stim_and_rec demo.
In the model linked, an xtra.mod is included however I also noticed that the corresponding pointers are not set and both xtra and extracellular mechanisms don't seem to be actually implemented into the cell (second guessing myself since why else would it be included in the modeldb entry but can't find any evidence in the code).
If my observations are correct, what is the difference in how ostim.mod works that allows it to stimulate extracellularly without the usage of the xtra and extracellular mechanisms?
I am assuming it is due to the drastic difference of ostim being based on photons, irradiance, and flux instead of traditional stimulation units. Which in that case brings up the question of why xtra.mod is included in the model?
Any point in the right direction of thinking would be greatly appreciated.
