Diffusion and concentration gradient

I think this is the result of neural regulation. Transport and the distribution of related molecules is completed under the control of the brain via some specific receptor proteins .

Recently I got a weird-shaped band on my western blot. It is like an upside-down of smiling face in each lane. I use the same loading ...
