When should scientific disciplines be capitalized?

Question

When writing motivation letters like SoP, or any other formal text, I don't know whether I have to capitalize sciences or areas of research.

For example:

I have been introduced to Neuroscience.
  I have been introduced to neuroscience.

Are there any criteria for capitalization?

Kris · Answer

When they are specific scientific disciplines. Words can also be used otherwise.
"This is not rocket science."
"I did not study Rocket Science."
