I am working on an assignment for my neuroscience course, and I'm running into a problem with one question which requires me to rewrite an equation into its nondimensionalized form. The equation is given below. and I need to convert it to the form by rescaling and shifting the given variables in the equation as I have already attempted to follow the nondimensionalization procedure given in the Wikipedia article on it, but however I do it, there are some variables on the R.H.S that simply refuse to go away to give me the form required. I'd be grateful for any help. Thanks!
