Greater incidence of depression with hypnotic use than with placebo

BACKGROUND Although it has been claimed that insomnia causes an increased risk for depression, adequate controlled trials testing this hypothesis have not been available. This study contrasted the incidence of depression among subjects receiving hypnotics in randomized controlled trials versus those receiving placebo. METHODS The incidence of depression among patients randomized to hypnotic d...

Hypnotic devices may be more than placebo.

The study attempted to assess the effectiveness of two devices in facilitating the induction of hypnosis in subjects preselected as low in hypnotizability. Undergraduates were exposed to no treatment (control) or one of four combinations of devices during the induction phase of being administered the Stanford Hypnotic Susceptibility Scale, Form B of Weitzenhoffer and Hilgard (1959). Analyses re...

Placebo Response Correlates With Hypnotic Suggestibility

Placebo response shares phenomenology and likely overlaps with substrates of cognition and personality. However, inconsistent findings abound regarding the potential link between suggestibility and responding to placebos. Here we directly probe whether suggestibility of the hypnotic type influences placebo response. Fifty healthy undergraduates underwent a standard measure of hypnotic suggestib...

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

Spaces with Conformal Dimension Greater than One

We show that if a complete, doubling metric space is annulus linearly connected then its conformal dimension is greater than one, quantitatively. As a consequence, hyperbolic groups whose boundaries have no local cut points have conformal dimension greater than one; this answers a question of Bonk and Kleiner.
