another usage

[Navi]

Are these both correct:

1-I have talked about some of the functions than the mind performs. These were all performed consciously. Now I want to talk about another, unconscious, function of the mind.
2-I have talked about some of the functions than the mind performs. These were all performed consciously. Now I want to talk about another function of the mind, which is unconscious.

Gratefully,
Navi.

I think you mean '...that the mind performs, not '...than the mind performs'.

If you make that change, then both versions are correct, though personally I prefer the first option.

You don't necessarily need the commas around 'unconscious' in the first sentence, but I think they serve to emphasise the nature of the function you wish to speak about and the fact that it is significantly different from those previously mentioned.

Thank you very much for all your replies Beeesneees.

I am sorry about the typo.

I think if we take away the commas and have:

Now I want to talk about another unconscious function of the mind.

we will be implying that the other functions were also unconscious.
Am I mistaken here?

[Beeesneees]

No, that's correct.
I just didn't explain it very well, sorry. :)
