Webb23 feb. 2024 · Spike waves happen when one or more brief spikes are followed by a slow wave, and this happens three times per second. Sharp waves happen over 80-200 milliseconds. What does it all mean? So EEGs show what is happening in the brain during the test, but why is this helpful in epilepsy? Sharp waves and ripples (SWRs) are oscillatory patterns produced by extremely synchronised activity of neurons in the mammalian hippocampus and neighbouring regions which occur spontaneously in idle waking states or during NREM sleep. They can be observed with a variety of imaging methods, such as EEG. They are composed of large amplitude sharp waves in local field potential and produced by tens of thousands of neurons firing together within 30-100 ms window…
