A Comparison of the Physiological and Behavioral Effects of Suvorexant and Zolpidem in Healthy Volunteers: A Randomized, Double-blind, Placebo Controlled Study
The primary objective of this study is to evaluate two pharmacotherapeutic approaches to sleep induction, both of which have been shown to be effective hypnotics, but may have unique side effect profiles. These profiles may have markedly different impacts on performance in a military setting. In this randomized, double-blind, placebo controlled study, the side effects of these drugs will be compared - suvorexant, a dual orexin receptor antagonist and zolpidem, a non-benzodiazepine gamma-aminobutyric acid (GABA) A agonist - in healthy controls comparable in age and gender to the target military population.

Optimizing Volunteer Comfort for Transcranial Electrical Stimulation (TES): An Assessment
Transcranial electrical stimulation (TES) utilizing weak electrical fields (\<5 milliamps of current - as proposed in the present pilot study) is an extremely safe therapeutic technique in use for over 40 years. During that time, TES has never been associated with a serious adverse event in a research setting nor a serious reported adverse event in a clinical setting. The main side effect associated with TES is irritation of the skin beneath the electrodes (as is commonly found from similar preparations used for polysomnography). The purpose of this pilot study is to identify the type of electrode preparation that maximizes subject comfort during transdermal/transcranial electrical stimulation (TES) using the NeuroConn DC Plus Stimulator.

Effect of a New Formulation of Vitamin B12 on Physical and Mental
This clinical study evaluates the effect of acute intake of a new vitamin B12 formulation on anaerobic and cognitive performance variables. One of the limiting factors for the potential beneficial effects of vitamin B12 is its bioavailability. This new formula improves this aspect, so that by improving plasma levels of B12 we will be able to relate whether this situation may be related to improved performance or cognitive tasks.
