Neural correlates of delayed episodic memory in patients with mild cognitive impairment--a FDG PET study.

abstract：:Schisandra chinensis is commonly used for food and as a traditional remedy for the treatment of neuronal disorders. However, it is unclear which component of S. chinensis is responsible for its neuropharmacological effects. To answer this question, we isolated α-iso-cubebene, a dibenzocyclooctadiene lignin, from S. ch...

However, it remains to be determined whether or not IL-6 rescues hippocampal CA1 neurons from lethal ischemia and prevents ischemia-induced learning disability.
