1. We evaluated the feasibility of using a simulated public speaking (SPS) test to assess the activity of anxiolytic drugs. SPS was achieved by requesting subjects to present a speech to an audiocassette recorder. Thirty volunteers were randomly assigned to one of three groups treated with 10 mg diazepam, 10 mg buspirone or placebo, under double-blind(More)
Experiments with a liquid metal alloy, galinstan, are reported and show clear evidence of Alfvén wave propagation as well as resonance of Alfvén modes. Galinstan is liquid at room temperature, and although its electrical conductivity is not as large as that of liquid sodium or NaK, it has still been possible to study Alfvén waves, thanks to the use of(More)
