WebSep 21, 2024 · Also, personalized detection criteria related to individual spindle power and peak frequency cannot be taken from the full data of the same sleep recording but have to be derived from “baseline” sleep data, that is, a separate period of sleep EEG data recorded either during the beginning of the same sleep session or during a previous sleep session … WebThe papers collected in this volume have the aim of integrating the contributions from two disciplines: psychoanalysis and neuroscience. Recent great developments in the latter offer the opportunity to build a bridge to psychoanalysis, providing an anatomo-functional basis for some of the functions in which the psychoanalytic theories of the mind are rooted.
