Memory distortion refers to a memory report that differs from what actually occurred. Characteristics. Memory’s fate is determined by factors present at encoding (when the memory is first recorded), storage (how and where the memory is represented in the brain), and retrieval (when the memory is reported).
Memory Distortion and Brain Much work over the past decade has focused on the neural regions supporting true and false memory. In search of a neural signature of true and false memories, researchers have employed a variety of neuropsychological, neuroimaging, and electrophysiological techniques. These include lesion studies, Positron Emission Tomography (PET), functional Magnetic Resonance Imaging (fMRI), electroencephalogram (EEG), eventrelated potentials (ERPs), and more recently transcranial stimulation, and near-infrared spectroscopy. A consensus is beginning to emerge that true and false memories activate different brain regions, leading some investigators to claim that they have located a neural signature of false memories. Specifically, the medial temporal lobe has been implicated in false recognition, while the prefrontal cortex has been implicated in memory monitoring errors [7,10]. Despite these advances, some studies have also found that true and false memories activate similar brain regions, including prefrontal cortex, parietal cortex and medial temporal lobe. There is at present growing excitement in the field of cognitive neuroscience. As this field advances, it should soon be possible to distinguish true from false memories reliably and consistently by observing brain activation. Someday it may even be possible to determine the veridicality of one’s memory for an individual event simply by looking at the person’s overall pattern of brain activity.
