...Each subsequent recital yields less and less activation of these areas of the brain. The best way to learn it is to space out learning trials...
...asked what the brain was doing differently during experiences which were remembered," Wagner says. "The scan showed greater activation in the left frontal and left temporal region when people paid attention to the semantic meaning of words...
...left frontal region is the area of the brain behind the temple. The left temporal lobe is the area behind that. Previous neuroimaging studies have identified the parahippocamal cortex, the inner wall of the left temporal region, as particularly important in memory formation. Due to advances in MRI techniques, the activated regions can now be localized with greater precision than previously possible...
Does this mean that the left frontal and left temporal regions of the brain are responsible for memory formation? A similar study done by James Brewer of Stanford University showed that different areas of the brain are responsible for remembering (and possibly retrieving, although that was not studied) different types of events. In Brewer's experiment, subjects were shown pictures, not words, and greater activity was concentrated in the right frontal and right temporal regions of the brain...
...scans to isolate particular regions of the brain responsible for memory encoding has important implications for medicine. An early symptom of Alzheimer's disease, for example, is the inability to learn and remember new experiences...
