Modulation of Visual Contrast Perception Associated With Dorsal Attention Network Connectivity Assessed by Magnetoencephalography

Human Brain Mapping, Volume 47, Issue 8, June 1, 2026.
Magnetoencephalography was used to identify the impact of spatial attention on primary visual cortical responses to stimuli of varying contrast levels. Enhancement of the maximal response of the visual cortex to high contrast stimuli was associated with synchronous communication between the dorsal attention network and visual cortex within the alpha ...

Validating Numerical Simulations to Support Experimental Testing of MRI Gradient‐Induced Heating of Passive Implants

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3584-3593, June 2026.
ABSTRACT Purpose Numerical simulations can be adopted to aid the evaluation of the interaction between switched gradient fields and metallic implants and estimate the possible temperature increase. Anyway, an analysis of the consistency of their prediction with experiments is lacking, differently from what can be found for exposure to radiofrequency ...

Magnetic and Electromagnetic signals related to tectonic activity: updates and new analyses on measurements in Central Italy [PDF]

Natural Hazards and Earth System Sciences, 2005
Tectonomagnetic field observations from absolute magnetic field levels have been collected in Central Italy since 1989 by means of a network of four absolute magnetometer stations, including the geomagnetic observatory of L'Aquila (42°23 N, 13°19 E) used

Influence of Solar Sails on Magnetic Field Measurements in Space Plasmas

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Solar sail technology is ready to be deployed in a satellite mission carrying a science‐grade magnetometer. In preparation for such a mission, it is essential to characterize the interactions between the sail and the ambient plasma that could affect the magnetometer readings.

Long‐Term Trends in the Calibration of the Cluster Fluxgate Magnetometer Instruments

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The calibration parameters of the Cluster mission's fluxgate magnetometer instruments have been determined and updated on a per‐orbit basis throughout the 24 years of the mission. Since there is no absolute field reference for vector measurements in‐flight, various spacecraft‐to‐spacecraft and instrument‐to‐instrument comparisons have been ...
