electric shock and memory

[Abu Anzar]

it is proved that all data in our memory are stored in wired network of neuron,

neurons are charged particle and v can say biological electron that carry ionic current (impulses) from 1 part to another

now the question arises here is that
q1) when one is subjected to current normally his memory do not disturbed why?? even that part may become worthless
q2) mentally disordered patients are subjected to high tension electric shock for settling their brain why? (it is showing that their is some relation b/w brain and electricity)

With regards

[david23]

electrical shock damages short term memories but not long term. ECT used for mental patients are I think considered inhumane, or I guess no longer used that much.

[Abu Anzar]

why not long term is there any system in brain that prevents long term?

[david23]

oooh man ok ok neurology is not my area, but my friend recently did something related to long term memory and behavior. Ok ok lets see long term memory has been known to be the generation of new peptides, so I believe those peptides remain the way they are after a shock.
I think short term memory is stored temporary, so a shock somehow destroys it. Wikipedia says it has to do with temporary potential in a neuron, which could make sense if a shock destroys or alters it.
Also it's been known there are no significant damages to the brain after a shock.

I hope that little helped

[Abu Anzar]

yeah!
its helped and I cover some stairs towards the goal,
if it is possible do mention wiki link here!

[david23]

yeah sure http://en.wikipedia.org/wiki/Short-term_memory

It doesnt explain the biological pathways, just general definitions though.

Actually, EST is used mostly on people with depression nowadays. It came into fashion around the time of the lobotomy, if I have heard correctly. The point of EST is to elicit a seizure, I think somewhere along the reasons of 'people seem to be more sedated after a seizure'.
There have been some really interesting experiments done in the past involving EST. Donald Ewan Cameron carried out some interesting tests where he shocked a person so much that he could no longer get any seizures out of the patient, and then kept them in a coma while playing repeating tapes of looping sound (from statements to just sounds), which he theorized would completely wipe their minds of any mental disorders.

One my friend said that most of his memory came back over many years but he can't remember things in sequence. Events are remembered in a disjointed manner after electric shock therapy

[Kinky]

Wow. I have never known about these facts. This is really amazing:)

It affects short-term memory because it is stored as transient neural excitations in the hippocampus or amygdala (for emotional memory). Long-term memory, on the other hand, is stored in some form of synaptic plasticity, such as long-term potentiation or long-term depression and therefore is not affected by electrical shock. LTP and LTD involve the number of receptors (AMPA receptors).
