Hormones are not directly involved in cognition, but are involved in
modulating the activity of neurons. For example, a deficit of
thyroxine can make a person slow, stupid, depressed or psychotic. If
you did have a brain in a vat, you would have to replicate the effects
of the endocrine system as well as the sensory inputs, and you would
have to simulate all this in a computer upload. It makes it more
difficult, but there's no reason why it couldn't in theory be done.
