A groundbreaking study has shown that as children age, excitatory brain activity decreases while inhibitory activity ...

A new study has shown how aspects of brain function change with age, revealing that excitatory processes in the brain ...

Gulbinaite explains, "I study brain waves and the effect rhythmic lights ... while others oscillate with maximum amplitude. This is exactly what occurred at higher strobe light frequencies ...

As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude ...

During a typical night’s sleep, the brain’s activity fluctuates. The first three stages of sleep are characterised by three types of brainwaves: alpha waves, theta waves and delta waves.

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. The amplitude (\(a\)) of a wave is the distance from the ...
