Slow potential topography

Topography of the human motor potential.

Inflaton potential reconstruction without slow-roll

We describe a method of obtaining the inflationary potential from observations which does not use the slow-roll approximation. Rather, the microwave anisotropy spectrum is obtained directly from a parametrized potential numerically, with no approximation beyond linear perturbation theory. This permits unbiased estimation of the parameters describing the potential, as well as providing the full ...

The "slow pathway" potential: fact or fiction?

The exact electroanatomic circuit responsible for atrioventricular nodal reentrant tachycardia (AVNRT) remains poorly understood. Initially, the pathological substrate was thought to be a small reentry circuit within the compact AV node (AVN).1 However, through a series of detailed histological studies,2 computer modeling,3 optical mapping,4 and uniquely insightful observations of tachycardia b...

Scalar Potential Topography can Simplify Interpretation of 2D Vector Fields

We demonstrate a new visualization technique to help researchers answer specific questions about 2D vector fields. Rather than directly display the vector field, the visualization isolates the integrable part of the field, integrates it to find a scalar potential, and displays the scalar potential as a height field. Scalar potential representation can be combined with direct field representatio...

The Steady State Visually Evoked Potential Topography and Vigilance

We report data which demonstrates a correlation between the magnitude of the Steady State Visually Evoked Potential (SSVEP) and visual vigilance. The SSVEP was recorded from 64 scalp sites and elicited by a 13 Hz uniform visual flicker presented while subjects undertook a visual vigilance task. Fifteen right-handed males were required to view three times a 180 second series of geometrical shape...
