Do simple or complex cells dominate the output of V1?

I’m trying to learn more about visual processing in the brain and had a quick question.

Is the output from V1 primarily influenced by simple or complex cell responses in V1? Or perhaps it is an even mix of both? Or perhaps it differs depending on whether the output is targeting the dorsal or ventral streams? I’m sure science has an answer…

Thanks for your help.

I don’t know the answer but I suggest reading this:

The Thousand Brains Theory predicts the answer will likely be the same in V1 and other regions as well.
