I've spent a few years studying biological modelling and simulation (of plants) but I've never heard of this distinction. Is it specific to neuroscience? What exactly is the "bottom" in a bottom-up approach?

Great question (to which I have no idea what the answer is). It seems to me that the various attempts are trying to simulate sets of emergent behaviours at different levels of the brain's "stack". I guess, one way of determining the success of a "lower level" simulation/emulation, is the emergence of known "higher level" behaviours?

It's a distinction that physicists have brought into the field, the bottom refers to the lowest level of detail, usually cellular but sometimes molecular.
