Task-dependent activations of human auditory cortex during pitch discrimination and pitch memory tasks.

19 Oct 2009 The functional organization of auditory cortex (AC) is still poorly understood. Previous studies suggest segregation of auditory processing streams for spatial and nonspatial information located in the posterior and anterior AC, respectively ... Read more...

Heart rate variability in novice pilots during and after a multi-leg cross-country flight.

29 Sep 2009 BACKGROUND: A pilot's workload induces autonomic nervous system modulations which could be related to a decrease of vigilance that could impair safety. Kinetics during flight and recovery are not well known. OBJECTIVE: The aim of this study was to ... Read more...

The relationship between body mass index and cardiopulmonary exercise testing in chronic systolic heart failure.

29 Sep 2009 BACKGROUND: Cardiopulmonary exercise testing (CPX) in patients with systolic heart failure (HF) is important for determining HF prognosis and helping guide timing of heart transplantation. Although approximately 20% to 30% of patients with HF are ... Read more...
