Involvement of M1-muscarinic acetylcholine receptors, protein kinase C and mitogen-activated protein kinase in the effect of huperzine A on secretory amyloid precursor protein-alpha.

abstract：:Using a guessing paradigm we measured visual sensitivity in the blind and normal half-fields of four cerebrally hemidecorticated patients. In the blind field, sensitivity was reduced by approximately 3 long units. Stimuli which produced significant detection also evoked conscious sensations of light and colour. Contro...
