    Sorry, but it's fairly well established, even scientifically, that
    without a brain, memories don't happen. Recall is verifiable. Absence
    of signal is falsifiable. Perhaps someone here will post the
    seventeen thousand pages of studies that have already been done....

    And we have 'seen' memories happen, with fMRI and with stimulation of
    specific areas of the, gee, the brain.

    And hey, here's one I found in three seconds-


      "Magnetic Resonance Imaging Volumes of the Hippocampus and the
    Amygdala in Women With Borderline Personality Disorder and Early
    Driessen M, Herrmann J, Stahl K, et al
    Arch Gen Psychiatry. 2000;57:1115-1122

    Previous research indicated that decreased hippocampal volume has
    been found in patients with post-traumatic stress disorder (PTSD) as
    well as in females who are survivors of early sexual or physical
    abuse. The authors attempted to look at possible volumetric brain
    differences in patients with borderline personality disorder (BPD), a
    disorder that is often associated with early childhood trauma. They
    compared 21 female patients who were diagnosed with BPD with 21
    matched controls and looked at MRI volumetric measurements of the
    hippocampus, amygdala, temporal lobes, and proencephalon.
    Neuropsychological testing examining memory function was also
    administered to both cohort groups. The authors found that the
    females with BPD had a 16% reduction in hippocampal volume and an 8%
    reduction in amygdalal volume bilaterally. No differences in
    neuropsychological testing were detected between the 2 groups.
    However, within the BPD group, no significant difference in volume
    measurements was seen in those who reported traumatic experiences
    compared with those who did not."


    Where else _you_ gonna look?

    Like I said, your rainbow ain't got a pot at its end.
