Is Perruchet's dissociation between eyeblink conditioned responding and outcome expectancy evidence for two learning systems?

30 Mar 2009 P. Perruchet (1985b) showed a double dissociation of conditioned responses (CRs) and expectancy for an airpuff unconditioned stimulus (US) in a 50% partial reinforcement schedule in human eyeblink conditioning. In the Perruchet effect, participants ... Read more...

[Antioxidant activity of different phenolic fractions separated from Euphrasia rostkoviana Hayne]

30 Dec 2008 Euphrasia rostkoviana Hayne (Eyebright) is a valuable part of the traditional folk medicine as an anti-inflammatory herb since centuries. Since oxidative stress may underlie as a key feature of inflammatory process, the methanolic extract ... Read more...

Iridoids from Euphrasia genargentea, a rare Sardinian endemism.

30 Dec 2008 The phytochemical study of Euphrasia genargentea, a rare species only present in Sardinia, led to the identification of iridoid glucosides, i.e. aucubin, catalpol, mussaenosidic acid and melampyroside, which allowed chemotaxonomic considerations on ... Read more...
