I believe the answer is:

idealist

I'm a little stuck... Click here to teach me more about this clue!

'no pragmatist' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'a catalogue of brain waves' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
'catalogue' could be 'list' (a catalogue is a list of items) and 'list' is found in the answer.
The remaining letters 'ide' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'producing' acts as a link.

Can you help me to learn more?

(Other definitions for idealist that I've seen before include "One seeking perfection" , "Detail is about person with aspirations toward perfection (8)" , "One sees things as they should be rather than how they are" , "Sail tide (anag.)" , "One who aspires to perfect standards" .)
