Some questions about the functionality of memory

[GreenDestiny]

Hi everyone!

 

On http://en.wikipedia.org/wiki/Karl_H._Pribram I read that "Drastic lesions can be made in animal brains which reduce, but do not extinguish memories (training), as demonstrated by Karl Lashley in the 1920s."

 

Does anyone know about these experiments? How is this seen today in neuroscience? Can memories be extinguished by brain lesions?

 

Another question I have refers to a different Wikipedia article: http://en.wikipedia.org/wiki/Memory#Physiology

 

It it you can read: "Other scientists who have investigated the nature of memory, namely neurologists John Carew Eccles and Wilder Penfield and biologist Rupert Sheldrake, have suggested that memories are a field phenomenon and are not stored in the brain at all, but rather accessed through neurological structures."

 

Does anyone know anything about these theories? If memories and the mind are not part of the brain, what is the brain good for in the context of memorizing things then? Is the brain actually needed for the functionality of memory according to these theories or could the mind theoretically access them without having or using a brain?

Memories are stored in the brain, but once the action is complete that the thought refers to, the brain stores the thought.
