Can I change the pressure amount of a brush line –drawn by mouse pen- after I drew it?

I am using Illustrator for doing some calligraphy, and I am not really experienced with this program.

I am using a mouse pen with pressure to draw/write calligraphy. My question is: Can I change the pressure amount after I drew lines using brush tool?

Let’s say I drew a line, it is good but still not satisfactory. I just want to do a little change in pressure amount in some segments –not all the line- on line. Does Illustrator give me this option?
