Monitoring brain activity of human subjects during delayed matching to sample tasks comparing verbal and pictorial stimuli with modal and cross-modal presentation: an event related potential study employing a source reconstruction method.

abstract：:We isolated nardosinone as a neuritogenic substance from Nardostachys chinensis. Nardosinone did not exhibit the neurotrophic activity but caused a marked enhancement of the nerve growth factor (NGF)-mediated neurite outgrowth from PC12D cells. Nardosinone-induced enhancement of the NGF-action was completely blocked b...
