The part about shuffling around salamander brains and memory returning is particularly fascinating as it runs contrary to Crick's "Astonishing Hypothesis" where he asserts that mind (including the soul) is fully contained within the physical brain. Your linked article said:
It happens all the time due to accidents and cerebrovascular accidents. It's also possible to study localization of function with real-time MRI scans. Non-locality of memory has been known for decades. It is one of the reasons I believe artificial intelligence is beyond my lifetime, because no one knows how it works.
None of this argues for any non-physical property of the mind. Just because memories are spread out doesn't mean they aren't embodied.
From the standpoint of ID vs evolution, I find it interesting that the level of redundency in the brain is staggering, compared, say to the redundency of the space shuttle's heat shield.
