Sentences with phrase «generate electrical potentials»

But it takes energy to generate electrical potentials, and, according to biophysics, this energy can come only from cellular metabolism.

One important complication here is that other body organs such as the heart also generate electrical potentials that spread through the body and summate with the potentials from the brain.

Pyroelectricity is the ability of certain materials to generate an electrical potential when they are heated or cooled.

Not exact matches

Electrical potentials are generated throughout the brain.

On Earth, the brightest auroras (the high - altitude glows often called the northern and southern lights) are generated when electrons in outer space near Earth are accelerated by large electrical potentials, or voltages, along the lines in our planet's magnetic field and slam into gas molecules in the upper atmosphere above polar regions.

As the tether moves through the Earth's magnetic field, an electrical potential of several thousand volts will be generated.

It's a unique approach that allows us to stimulate single neurons and monitor the tiny fluctuations in their electrical activity that generate action potentials.

A major challenge in tapping such electrical potential is that the voltage created is tiny — a fraction of that generated by a standard AA battery.

A major challenge in tapping this electrical potential is that the voltage created is tiny — a fraction of that generated by an AA battery.

Fusion, the power that drives the sun and the stars, is the fusing of light elements that produces massive amounts of heat with the potential to generate electrical energy.

The following year, based on experiments in the giant squid axon, British biophysicists Alan Hodgkin and Andrew Huxley described how ion flow across the cell membrane generates the electrical spikes — called action potentials — that constitute these signals.

Sunlight causes the electrons to leap from one band to the next creating an electrical energy potential The energy difference between the bands — the band gap — determines how much solar energy will be absorbed and how much electrical energy is generated.

Or, we could use that hydro - generated electricity to power a pump and pump that water up into a water tower, turning the electrical energy back into potential energy.
