Is "for 'i' in target_pop" an error in this code occured in Model.py

[lepodl]

 for target_area, source_area in product(area_list, area_list):
        if source_area != target_area:
            for target_pop, source_pop in product(population_list, population_list):
                if 'I' in target_pop:
                    synapse_weights_mean[target_area][target_pop][
                        source_area][source_pop] *= cc_weights_I_factor
                    synapse_weights_sd[target_area][target_pop][
                        source_area][source_pop] *= cc_weights_I_factor

Is "for 'i' in target_pop" an error in this code in Model.py? Inhibitory weights are enhanced by factor cc_weights_I_factor, but you choose the inhibitory target_pop as maniuplating object.

Hey @lepodl,

Thanks for reporting here! As far as I can see, the implementation is consistent with the desired behavior. From the second-to-last paragraph of the materials and methods section in (Schmidt et al. 2018): "Therefore, we introduce two factors chi and chi_I to scale the weight of synapses onto excitatory neurons by chi and onto inhibitory neurons by chi_I [emphasis added]."

In the above code, cc_weights_I_factor is precisely this factor chi_I. Do you agree that the implementation is consistent with the manuscript or am I missing something here? Maybe it is important to mention here that a small fraction of cortico-cortical projections in the model target inhibitory neurons.

Cheers, Alex

PS: Larger blocks of code can be enclosed by ``` to make them better legible, see e.g. here.

Hi, I agree with @AlexVanMeegen , I think the implementation is in line with the manuscript. To make the code snippet more readable, I edited @lepodl 's comment to add syntax highlighting and proper code formatting.

Okay, it looks like I made a mistake, thank you！！

Most welcome! Thanks again for reporting, certainly better to double check than having a bug. I'll go ahead and close the issue.
