Damn oxygen regulators centred around me (8)

I believe the answer is:

amygdala

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

'me' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?

'damn oxygen regulators centred around' is the wordplay.
'damn oxygen regulators' becomes 'amygdal' (I can't justify this - if you can you should give a lot more credence to this answer).
'centred' becomes 'centralized' (synonyms).
'around' says to take the centre.
The central letter of 'centralized' is 'a'.
'amygdal'+'a'='AMYGDALA'

Can you help me to learn more?
