A slice of pi : an exploratory neuroimaging study of digit encoding and retrieval in a superior memorist.

abstract：:A deficit of declarative memory is a common sequela after a hypoxic episode. While the role of gray matter changes (i.e., atrophy of hippocampal formation) as mainly responsible for memory loss has been emphasized, the role of the white matter damage has so far been neglected. The present study was aimed at evaluating...
