For some migraine sufferers, the pain is preceded by visual artefacts called aura, which can include seeing wavy lines, flashes of light or blind spots. These are triggered by a wave of electrical ...

A surprising new function of essential hearing proteins may explain why some genetic mutations and common antibiotics lead to permanent deafness.

No body, no dopamine, no problem. Scientists have successfully coached lab-grown brain tissue to solve a classic robotics challenge, proving that the will to learn is hardwired into our neurons.

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut.

Researchers at UT San Antonio have uncovered new details about electrical signals happening within nerve cells, deepening scientists' understanding of the brain. Their work appears in the study, ...

Human beings and other animals send electrical signals via the central nervous system. The Venus flytrap, which lacks such a nervous system, also sends rapid electrical impulses, which are generated ...

Researchers have created an improved method for turning genes on and off using electrical signals. Researchers, led by experts at Imperial College London, have developed a new method that allows gene ...

Like human nerves, bacteria in biofilms can communicate using electrical signals. Now, studies show that other species can also tune in to these pulses. Bacillus subtilis swarm. In Gürol Süel’s lab at ...

Researchers have developed a new acoustic fabric converts audible sounds into electrical signals. They designed a fabric that works like a microphone, converting sound first into mechanical vibrations ...

Epithelial conversation An epithelial cell-coated microelectrode array with 60 precisely placed electrodes detects the minute electric signals generated when the cells are injured. (Courtesy: UMass ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...
