    ### Pictures are not stored as 2D images. The ability to recognize
    previously seen images is distributed over a wide range of cortical fields,
    including the exastriate cortices, parietal and even frontal cortex. The
    engram is probably a pattern of synaptic strength modifications, similar to
    LTP and LTD, as well as synaptic neogenesis and pruning.
