Archaeological Prospection, EarlyView.ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Archaeological Prospection, EarlyView.ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Epilepsia, EarlyView.Abstract Objective Accurate presurgical evaluation should assess not only the location but also the spatial extent of epileptic activity relative to the surgical cavity, a practical approximation of the epileptogenic zone. We evaluated how electromagnetic source imaging (EMSI) and hemodynamic responses to epileptic discharges relate to the surgical ...

Exploring the Sensitivity Limits of Neuronal Current Imaging With MRI and MEG in the Human Brain
Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.Combined spin‐lock fMRI, MEG, BOLD‐fMRI, and phantom experiments reveal that physiological neuronal magnetic fields lie below the in vivo detection threshold of the current spin‐lock implementations at 3T, defining quantitative sensitivity limits for MR‐based neuronal current imaging. ABSTRACT Conventional BOLD‐fMRI relies on hemodynamic responses that

Annals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.We adapted the FREQ‐NESS pipeline to event‐related MEG data from 140 adults during a melody‐recognition task, revealing an age‐related reorganization of frequency‐specific brain networks. Younger adults showed task‐related reduction in the prominence of alpha networks, whereas older adults maintained prominent slower alpha networks (8.6–10.0 Hz) across
