Stereo-electroencephalography identifies N2 sleep and spindles in human hippocampus

Physiological activity and related functions of the hippocampus are clearly modulated by sleep. For example, the sequences of hippocampal neuronal discharges in rats occurring during a space exploration are reactivated during both non-rapid eye movement (NREM) and rapid eye movement (REM) sleep (Wilson et al., 1994; O'Neill et al., 2008). In humans, this so-called hippocampal replay was also highlighted in positron emission tomography (PET) in healthy volunteers during slow-wave sleep (SWS) the night following a mnesic episodic learning task (Peigneux et al., 2004).
