They vary according to the source and the region stimulated, if I recall
correctly. You can gently press the sides of your eyeballs with your
eyes closed to generate phosphenes if you like. Somehow I suspect you
already know that, though.
Your choice of verbs is a little obscure, but the subject stimulated
over MT with the appropriate latency were unable to reliably indicate if
a stimulus was moving or not. It's years since I read it though - have
learned a lot since then, perhaps I should dig it out ... !
