Webb6 sep. 2024 · At the frontal level, frontal sharp transients (FSTs), first described by Monod as “encoche frontale” ( Monod et al. 1960 ), are recorded on neonatal electroencephalogram (EEG) during a very specific period, at the very end of gestation, just before the physiological transition from in to ex utero life ( Lamblin et al. 1999; Bourel … 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…
