Hello,

I want to ask basic question how to translate the equation of alpha function.

When we think alpha function below;

![image|365x63]

Then differentiate g(t) with respect to t,

Then, define x = t/tau, resulted dx/dt=1/tau.

However, it looks incorrect since the result doesn’t match the example of Brian2 website.

How can we introduce the equation used in Brian implement??

Thank you very much for your kindness for me in advance!
