How would it look if I put online courses on my CV?

[warm-valley]

At my university we aren't allowed to take classes outside from what the department has pre-approved, so I didn't have many opportunities to take other classes. My undergrad field and what I'm planning to pursue in grad school are different (computer science -> neuroscience), would it look bad if I mentioned some MOOC neuroscience courses under a "other classes / workshops" section in my CV? Or would it not have much of an effect anyway?
