    Narrow- and broad-band spectral changes after hemispherotomy in an awake representative patient, displaying marked electroencephalography (EEG) slowing of the isolated cortex. by Michele Angelo Colombo (22446342)

    Published 2025
    “…In the middle panel, the topographies of Slow Delta Power, indexing the power spectral density (PSD) of low-frequency activity (0.5–2 Hz, hereby estimated under average reference for display purposes), show a marked inter-hemispheric asymmetry post-surgery. <b>(C)</b> The EEG PSD, averaged by geometric mean across intrahemispheric bipolar derivations, reveal an increase of slow frequency activity (<2 Hz) and a broad-band steepening of the PSD over the disconnected hemisphere post-surgery, which is evidenced in the inset graph by the linear fit of the PSD under double logarithmic axes (power-law fit). …”

    Group-level narrow- and broad-band spectral changes after hemispherotomy reveal a marked EEG slowing of the isolated cortex, robust across patients. by Michele Angelo Colombo (22446342)

    Published 2025
    “…<b>(B)</b> The PSD in the Slow Delta band (0.5–2 Hz) was significantly larger in the disconnected (Discon) than in the contralateral (Contra) cortex, only in the session after surgery. <b>(C)</b> Following surgery, slow wave activity increased in the disconnected cortex, as indexed by a significant pre to post increase of the Slow Delta PSD in the disconnected cortex (i.e., positive post-pre differences in the disconnected cortex). …”
