I caught your point, but I was correcting your strawman of the state of play - i.e. I wanted to make clear that neuroscience is not at the point where it can fully make claims to that extent.
IMO, the most interesting phenomenon is consciousness. It is relatively straight forward to demonstrate how functional properties, such as might be performed by a computer (e.g. information processing, input/output, and so forth), may be instantiated by chemical structures. However, things quickly become difficult if you try to work out how consciousness can be explained in such terms. Some would maintain that there is an 'explanatory gap' which can never be bridge by empirical science. I am undecided myself, but it is certainly a fascinating theoretical issue.
