Someone will give a more intelligent answer than me, but I think that the biggest lag
is at the level of the retina, where receptors take a long time to accumulate before
providing a potential strong enough to generate an action potential (how much more
cursory can you get?). In the cochlea, all that happens is a travelling wave that
propagates up the cochlea (2-3 ms) and a transduction in the inner hair cells, which
takes a ms or so.
