Brain after (electrical) blackout I was wondering what happens if we lose all electrical impulses in our nervous system for a minimum amount of time. So first of all it is obvious that we will break together, as we are dead while we are in black out state, but I am interesting in the "afterwards".
I could also put it this way: 
Is our brain like a RAM or a Harddrive? 
So, if we have a complete elec. blackout, is our memory erased?
Or is our consciousness based soly on the synapsis in our brain and does not care about the electrical state?

If "we" includes other animals down to frogs, then the answer may be that the structure could survive.

  Preparations with chronically implanted electrodes showed that there
  are periods during which no electrical activity is present in the
  brain of intact, non-anesthetized frogs sitting unconstrained in water
  in a jar. The activity appeared immediately upon stimulation.
  
  The results obtained confirm the suggestion of I. M. Sechenov that the
  electrical activity of the brain occurs either reflexly, or is due to
  direct effects on the brain. Without such effects, there is no
  electrical activity.


As in a flash drive, there should be a distinction between "electrical potential" and "electrical activity"

An "older" part of our brain is named reptilian and extrapolation from the frog would be tempting. I have no background in biology, but since animal models are generally accepted, would say that we may well be the same unless evidence shows us to be different. 

To support this intuitively:  an instant view of electrical state of our brain would contain many fewer bits of information than the topology of its whole network. paul_wi11iams
