Sharp wave
Webb13 sep. 2009 · Sharp wave–ripple (SPW-R) complexes in the hippocampus-entorhinal cortex are believed to be important for transferring labile memories from the hippocampus to the neocortex for long-term storage. WebbEncoches frontales is a normal graphoelement of the neonatal EEG, marked by biphasic and synchronous frontal sharp waves. As seen very well in this page, encoches frontales classically have a small initial negative phase, then a slower positive phase with overall amplitude up to 150 microvolts. They usually resolve by 46 weeks PMA.
