These slides are taken from  Susan Greenfield's presentation  concerning visualization of dynamic processes in the brain and her sweeping new theory of consciousness.  Greenfield tests her model against 5 different ways we think of consciousness, particularly our sense that there are "degrees" of being conscous Greenfield points out that Electrophysiology models the brain at tiny resolution and microsecond time intervals versus the commonly seen fMRI scans with poor resolution and long time scales. There is a huge gap between what these two models can say about what is happening in the brain. Greenfield's method bridges this gap using voltage-sensitive die imaging,  This method shows a mid-range number of cells ( a few million) at short time interval (18 ms in the above slide). This gives a mental model of consciousness that she compares to a stone being thrown in a puddle. In this talk, she extends that model in quite a bit of detail. From 1:34:17 onward, she presen...
