Can a human memory be erased?

    Your brain is constantly removing memories, it's a natural process.

    Stress, lack of sleep, and even diet have major effects on sleep

    it sure can - but a lot depends on whether you want them to be still alive after the process

    Yes. As others have said. Memory (though intangible) is stored in a tangible way, through physical -extremely complex- means in specific parts of your brain. In theory one could literally pluck one of these memories from your brain.... in THEORY. In practice however, it's impossible. 

    Through emotional trauma, physical trauma, or even through natural processes (in which your brain does 'maintenance' to be healthy), you lose memories. Loss of memory is both a natural and not-natural part of life.

    Nam-Myoho-Renge-Kyo.

    Yes, ill explain:

    Neuroimaging techniques:

    1. The just recently built INUMAC MRI machine (for imaging Neuro disease Using high-field MR, And Contrastophores) can image a area of about 0.1mm, or 1000 neurons, and see changes occurring as fast as one-tenth of a second.

    It would allow much more precise functional imaging of the brain at work, than is currently available.

    Where normal hospital scanners can see down to resolution of about a cubic millimeter (roughly 10,000 neurons per pixel), INUMAC will be able to see roughly ten times more acutely, with a resolution of 0.1 mm, or 1000 neurons, and observe changes inside the living brain occurring at 1/10 of a second.

    This will be a huge leap forward for brain researchers, allowing them to learn more about how the brain functions.

    Functional imaging, which follows brain activity by watching neuron excitation, could be taken to a whole new level of detail and reveal structural complexities we currently cannot see.

    2. Combine the INUMAC MRI machine with Jack Gallant's work at Berkeley where he can deduce what images someone is looking at from their brain activity. (you can see Ted Talks on YouTube of Jack Gallant's work)

    3. Also now there is a technique to detect whether or not a person posses a specific memory.

    Stanford Professor of psychology, and neuroscience Anthony Wagner has come up with a technique using a FMRI machine, and a computer algorithm detecting blood flow in the brain.

    The computer algorithm looks at this blood flow to detemine whether or not it reperesents a memory, or a novel experience.

    So the FMRI machine scanned the brains of the people, looking at the 2000 photographs, and the algorithm studied the blood flow, and tried to detemine ehich ones represented memories Versus new experiences, and the technique was right 75 to 95% of the time.

    4. So combine the INUMAC, Jack Gallant, and Anthony Wagner's work, with the latest CT scanners with Magnetoencephalography (MEG), and Electroencephalogram (EEG) all together, to see the electro signals, happening in real time, and to get a complete picture of what is going on in the brain.

    Ionizing techniques:

    5. Then modify a Gamma Knife machine to be able to ionize neurons at micron scales using gamma waves, or X-Rays (gamma waves can pass through something as small as an atom).

    6. You do not need to find, and ionize neurons all neurons to erase a bad memory, 10, to 25% of ionizing the neurons that hold a bad memory could be enough.

    7. Ask the person about the bad memory, then locate the bad memory, then ionize the bad memory, then repeat the steps 1, 2, and 3, over, and over, till the bad memory is gone.

    8. Erase the most recent bad memories to avoid confusing the person, if lots of bad memories have to be erased.

    I have talked to neuroscientists who have said this technique is not impossible it just has to be built, and tested.

    Yes. It can be erased completely or selectively. Brain injury can do it. In fact our own body does it. Short term memory is routinely erased. Only the important memories, important to us personally or for survival, are stored as long term memory.
