The 7-tesla acquisitions, facilitated by the use of a customized radiofrequency coil configuration and cardiac gating, achieved isotropic resolution of 6 mm, reported researchers from the Berlin Ultrahigh Field Facility (BUFF) in Berlin, along with co-authors from other institutions including Charité University Medicine in Berlin, the German Cancer Research Center in Berlin, and the University ...

AIMS Cardiac voltage-gated sodium channels control action potential (AP) upstroke and cell excitability. Intracellular calcium (Ca(i)(2+)) regulates AP properties by modulating various ion channels. Whether Ca(i)(2+) modulates sodium channels in ventricular myocytes is unresolved. We studied whether Ca(i)(2+) modulates sodium channels in ventricular myocytes at Ca(i)(2+) concentrations ([Ca(i)(...

BACKGROUND The issue of how differences in timbre are represented in the neural response still has not been well addressed, particularly with regard to the relevant brain mechanisms. Here we employ phasing and clipping of tones to produce auditory stimuli differing to describe the multidimensional nature of timbre. We investigated the auditory response and sensory gating as well, using by magne...
