Title: Do we have the tech to erase a human memory, with the INUMAC MRI machine, and

...the Gamma knife machine.
I think it is currently possible to erase a human memory in today's current technology, and this is why below.
Standard hospital scanners have a spatial resolution of about 1 millimeter, covering about 10 000 neurons, and a time resolution of about a second.
The INUMAC will be able to image an area of about 0.1 mm, or 1000 neurons, and see changes occurring as fast as one-tenth of a second.
But it is just the BOLD signal your seeing, but it could be accurate enough, if the INUMAC can magnify 1000 neurons.
The Gamma knife could be modified to be able to ionize neurons at smaller then micron scales, just the ball lenses would have to be worked on.
Remember a gamma wave can pass through something as small as an atom.
So ionizing a group of neurons at micron, or smaller levels should be no problem.
After studying neuroscience, I realized the you do not have to ionize ALL the neurons that hold a specific memory, and it does not matter how much the specific memory is distributed around the brain, with some neurons holding part of the  whole memory in one place in the brain, and another part of the memory in another place in the brain.
Just ionizing SOME of the neurons that hold the memory is enough to disrupt the whole memory.
You do not need to ionize ALL the neurons that hold the bad memory.
Which is good news, because trying to find all the neurons in the brain that hold that specific memory would be a VERY difficult task, almost like finding a needle in a forest difficult.
Combine these two technique's with latest MEG, EEG, and PET equipment, and you could have a fully functioning memory erasing machine
Electroshock treatment is not specific enough to erase certain memories, and ZIP (Zeta Inhibitory Peptide) used to erase memories in mice is not specific.
Just think for a minute how dangerous electro shock treatment is, I think it can induce seizure's, or brain damage, and you are erasing good memories that the person wants to keep.
With a modified gamma knife machine you would be ionizing small groups of neurons, in smaller than micron areas, so as you ask the person to recollect the specific memory, you see where it is located in the brain in the neuronal connections, and you would just keep ionizing small amounts of groups of neurons,  with the modified gamma knife, and just keep asking the person to keep recollecting the memory, and eventually the memory will become hazy, and he won't be able to recall the bad memory anymore, thus the bad memory has been erased.
So the person is now happy, better he can not piece together what is making him upset, than be unhappy, and depressed, and this was all done safely, more safe the electroshock treatment.
All this was achieved without erasing ALL the memories that were holding that specific bad memory.
The point is you do NOT have to erase ALL the memories that hold a bad memory.
Is just even if it did work, nobody care enough to build it to help people, get rid of their bad memories.
If everybody got rid of their bad memories  the whole world would be happier, FACT.
Do you think it is possible with current technology right now to build this.
I am grateful for your help, anything helps even a few words

The gamma knife is a bit blunt for zapping individual neurons. You might do better with a cyberknife, but even then, we don't know how memory is distributed. Given the known process of slow recall with gradually increasing detail, it is more likely to be retained in k-space rather than real space so you might end up with a hugely detailed picture but no idea what it signifies or why it matters.

I think you'd have better results using chemical means to prevent memory reconsolidation (
