Well I'm not sure, but I tend to think that if conciousness is transmitted such that could transfer past life memories for example then it would mean that conciousness is kind of like the cloud where memories are stored.
If only we had a means to turn the receiver off keeping it in tact then able to restore its link to its conciousness then its conciousness should be able to transmit the missing memories of our concious experiences that occurred while the receiver was turned off.
Well the good news is we can turn the brain (alleged reciever) off using anaesthetic (i have been under anaesthesic myself during a hospital procedure), the bad news is that except for where only a partial state of anaesthetic has been achieved patients will have no recollection of what happened or even of the passage of time while they were under anaesthetic.
Personally I think this may count as evidence against the idea that brains are merely the passive recipient of conciousness.
Then there is the research on how memory is actually stored in the brain;
Memories are formed by changing the connections between neurons.

It could be that brain memory is redundant, but one wonders why this redundancy evolved if there was no selection pressure in favour of it (which I wouldn't expect there to be if we could rely on transmitted memory for survival).
I'm personally open minded to the existence of concious spirits, I'm just not convinced that there is clear evidence of their existence for what its worth.
