Not with neither and nor
When a clause with neither or nor is used after a negative clause, we invert the subject and the verb after neither and nor:

He hadn’t done any homework, neither had he brought any of his books to class.

We didn’t get to see the castle, nor did we see the cathedral.

Conjunctions

Neither do I, Nor can she
We use neither and nor + auxiliary/modal verb + subject to mean ‘also not’:

A:
I hate snakes. I can’t even look at a picture of a snake.

B:
Neither can I.

Not: I can’t also.

A:
Jacqueline doesn’t drive.

B:
Nor does Gina.

Not: Gina doesn’t also.

See also:

So am I, so do I, Neither do I

Not … either
We can use not … either to mean ‘also not’, but we do not change the word order of the auxiliary or modal verb and subject:

A:
I haven’t ever tasted caviar.

B:
I haven’t either. (or Neither have I./Nor have I.)

A:
I didn’t see Lesley at the concert.

B:
I didn’t either. (or Neither did I./Nor did I.)

In informal speaking, we often say me neither:

A:
I can’t smell anything.

B:
Me neither. (or I can’t either.)
