Should academic experience from other domains be included on a CV? As an undergrad, I was a double-major in neuroscience and music. Now, I'm working on putting together a CV for applications to master's programs in neuroscience. But, my thesis work was done in the music department and unrelated to neuroscience whatsoever. Should I include this on my CV, or would it be seen as irrelevant "padding" of my CV? (I'm not really concerned about shoring up my experience, as I've had several years of directly relevant work experience since I finished my bachelor's degree.)
If your undergraduate program requires a Bachelor's Thesis, graduate school admissions committees might expect to see it on your CV. Completely omitting your thesis in your CV might raise questions.

Your ability to do independent work is also important, even in another field. If your thesis work is not related to your graduate school field, I would mention it but not focus on it. (i.e., include the title and one sentence summarizing what you did). If your Bachelor's Thesis is publicly accessible (and it is a good thesis), citing it in your CV cannot hurt.
