Hallo @ Sidra,
in order to enrol for an M.Sc. in Neuroscience you'll need a Bachelor degree in a related field, e.g. in medicine, pychology, biology or even linguistics, depending on the design of the study course.
I found an English-instructed programme at the University of Oldenburg, which requires a Bachelor's degree in the fields of neuroscience, biology, or in another related field (e.g., psychology) or in natural sciences and mathematics (e.g., engineering, informatics).
You will find the full information here: https://www2.daad.de/deutschland/studienangebote/international-programmes/en/detail/4672/#tab_university
I hope my answers were helpful and I’ll be very pleased if you contact me again with further questions. I'm a member of the mbeon-staff and I‘ll be glad to guide over a longer period of time. mbeon is an online advisory service for migrants via the mbeon-app, which you can download on your smartphone for free. You'll find me in the mbeon-app under my location „München” and then my name “Frau Müller“ and get confidential one-to-one advice in a safe virtual room where nobody can read messages.
