Is There Any Electrical Activity in the Brain?

Pigs were revived to some extent, but their brains did not show any electrical activity. This could be because of two reasons: the solution they had injected and an anaesthetic also in that solution. So maybe in future, they could tweak the parameters, keep the maybe a, remove the anaesthetic component from the fluid and maybe elevate the fluid to the average normal pig blood temperature. Ad maybe that could possibly even demo trate some activity, electrical activity, in the brain. In this experiment, they were able to see heightened celular activity and organic activity,. They also observed the involuntary twitching of pigs necks and various other muscles whenThis happened, when they injected the solution.
