For the first time, the team has provided compelling evidence that the brain's characteristic rhythmic patterns play ... we propose that the brain uses waves to perform computations in a highly ...

A research team has discovered a surprising phenomenon that could revolutionize how we think about signal amplification. Just two tiny vibrating units can, when connected with a delay, amplify their ...

Distant quasars may hold the key to spotting elusive gravitational waves—and revealing hidden dimensions of the universe.

Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node, or SA node. This results in an upright P wave in lead II on the ECG.

Ocean Waves Men have always been fascinated, and sometimes awed, by the rhythmic motions of the sea's surface. A century of observation and experiment has revealed much about how these waves are ...

When faster, it is referred to as an accelerated junctional rhythm. Because the electrical activation originates at or near the AV node, the P wave is frequently not seen; it can be buried within ...
