Cortical activation during menopausal hot flashes.

Objective: To determine regions of brain activation associated with menopausal hot flashes and sweating.

Design: Controlled laboratory study.

Setting: University medical center.

Cognitive avionics and watching spaceflight crews think: generation-after-next research tools in functional neuroimaging.

Confinement and isolation have always confounded the extraordinary endeavor of human spaceflight. Psychosocial health is at the forefront in considering risk factors that imperil missions of 1- to 2-yr duration. Current crewmember selection metrics restricted to behavioral observation by definition observe rather than prevent performance degradation and are thus inadequate when preflight training cannot simulate an entire journey.

Learning-related fMRI activation associated with a rotational visuo-motor transformation.

The unique ability to learn transformed or altered visuo-motor relationships during motor learning (visuo-motor transformation learning) has engaged researchers for over a century. Compared to other forms of motor learning (e.g.
