The hydrogen-bonded interactions of chloral hydrate and halide ions have been investigated conductometrically at 25.00 degrees C in aqueous solutions. In spite of the strong competing effect of water, the 1:1 associates have relatively high stability constants, in the order of chloride greater than bromide greater than fluoride approximately equal to iodide. The rather low stability of the fluo...

The vast majority of investigations on central auditory processing so far were conducted under the influence of an anesthetic agent. It remains unclear, however, to what extend even basic response properties of central auditory neurons are influenced by this experimental manipulation. We used a combination of chronic recording in unrestrained animals, computer-controlled randomized acoustic sti...
