conge I dont want to make any noise. So I think it would be good to answer u in the other tongue.
Since I got a master degree in US, maybe some of my experience would be a good fit for u.
I am not sure if the brain science background you mentioned is something like PHD or research projects in some labs with big name. If not, only an online CS master probably leads you to some positions we call code monkey. If you have time and money, one more CS PHD would be a better choice. If you like to be code monkey instead of researcher, thats another story.
If you have remarkable exp of your field, then just take some courses and go enjoy your job.
Good luck.
