Patricia Churchland neurons movement decision There are many levels of organization in nervous systems. Hence we aim to explain mechanisms at one level in terms of properties and dynamics at a lower level, and to fit that in with the properties at the higher levels.

For some, it was somehow supposed to lead to the truth about these phenomena, not just to tidy things up a bit. Patricia Churchland philosopher analysis ends I used to suspect that in the brain, time is its own representation. I now think the problem is so much more complicated.
