Physicists have shown for the first time that electrical signals in the human brain are amplified by noise. This effect is called ‘stochastic resonance’ and is well known in a wide range of systems, ...

Studying how brain cells respond to signals from their neighbors can aid the understanding of cognition and development. However, experimentally measuring the brain's activity is complicated. Neuron ...

Researchers at AppliedPhysics.org have published an exploratory study in Biosystems examining whether mathematical acoustic signal ...

Even in the best designs, noise and interference sneak in to reduce the signal-to-noise ratio (SNR), obscure desired signals, and impair measurement accuracy and repeatability. Digitizing instruments ...
