  2. Age-related decline in sleep-dependent memory consolidation
    Rebecca Spencer; Fiscal Year: 2007
    ..In doing so, treatments for memory decline can be more appropriately targeted: if the lack of sleep benefit is related to decreased sleep quantity or quality, therapies which enhance sleep may improve age-related decreases in memory. ..
