Sentences with phrase «electrical impulses travel»

In the 19th century, the pioneering neuroanatomist Santiago Ramón y Cajal theorized that information was processed in our heads each time an electrical impulse traveled across a synapse, the gap between one nerve cell and the next.

Not exact matches

Electromagnetic waves travel over vast distances, so perhaps there is some way the electrical impulses that generate thoughts could be transmitted from one person to another.

There, they modulate the electrical impulses that travel between our brain and our organs.

The cells respond to vibrations by producing electrical impulses that travel via nerves to the brain.

A small area of special tissue in the right atrium called the sinoatrial (SA) node starts an electrical impulse (it's like the heart's spark plug) that will eventually travel down special electrical tracts (AV node, Bundle Branches, Purkinje Fibers — the heart's «wiring») within the heart and cause the heart muscle to contract (see Figure 2 below).

Only a fraction of the electrical impulses are able to travel across the AV node and down through the heart's normal conduction system (the «wiring») to make the ventricles contract.

These cells help translate air vibrations caused by sound into electrical impulses that travel to the brain.

From the AV node, the electrical impulse then travels through a common bundle of specialized fibers that then divides into branches to the left and right ventricles and then further branch into many tiny fibers embedded between the muscle cells.

Curiously, cold showers seem to leave many feeling happy (I'd be more inclined to cry), and research suggests this comes from the surge in electrical impulses that travel from the nerve endings to the brain.
