Thalamic connectivity mirrors spatial maps of network dysfunction in nonlesional focal epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Focal epilepsy is increasingly conceptualized as a network disorder, yet the extent to which network dysfunction reflects a shared phenotype remains unknown. Spatially conserved patterns of network dysfunction may implicate a centralized mechanism underlying widespread impairment.

Selective Modulation of Evidence Accumulation by Hippocampal Theta Oscillations During Mnemonic Decision‐Making

open access: yesHuman Brain Mapping, Volume 47, Issue 7, May 2026.
Hippocampal theta power during memory retrieval predicts evidence accumulation in a mnemonic similarity task. Trial‐level MEG signals were integrated with a linear ballistic accumulator model, revealing that theta oscillations modulate decision dynamics, linking neural variability to memory‐based discrimination performance.

Responsitivity Measurement of a Lorentz Force Transducer for Homogeneous and Inhomogeneous Magnetic Fields

open access: yesProceedings, 2018
This paper reports a MEMS gradiometer consisting of two independent, laterally oscillating masses on a single chip with integrated optical readout featuring a responsitivity of 35V/T at resonant operation.

Compact Magnetic Gradiometer and its Astatization

open access: yesProcedia Engineering, 2015
AbstractWe present a compact (10-cm head size, 3-cm base) axial magnetic gradiometer with a method of its astatization (i.e. suppression of false response to homogeneous field). For astatization, we use two integrated orthogonal sensors and a second-order polynomial correction; after astatization the gradiometer error is suppressed more than 1000×. The

Sub-femtotesla scalar atomic magnetometer using multipass cells

open access: yes, 2012
Scalar atomic magnetometers have many attractive features but their sensitivity has been relatively poor. We describe a Rb scalar gradiometer using two multi-pass optical cells.

Atypical Change Detection in Sound Sequences: A Behavioral and Magnetoencephalography Study in Congenital Amusia

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 9, May 2026.
When passively listening to oddball sequences during magnetoencephalography recordings, individuals with congenital amusia show abnormalities of mismatch negativity for frequency deviants in the right temporal and right frontal cortices, whatever the stimulus onset asynchrony and change size.

Oscillatory Markers of Interoceptive Attention: Beta Suppression as a Neural Signature of Heartbeat Processing

open access: yesPsychophysiology, Volume 63, Issue 5, May 2026.
ABSTRACT Interoceptive attention refers to selectively attending to internal bodily signals to guide perception and behavior. Cardiac interoception, in particular, has been proposed to play a key role in self‐regulation and emotional awareness, yet the neural dynamics underlying attention to cardiac signals remain incompletely understood.

Quantum test of the equivalence principle for atoms in superpositions of internal energy eigenstates

open access: yes, 2017
The Einstein Equivalence Principle (EEP) has a central role in the understanding of gravity and space-time. In its weak form, or Weak Equivalence Principle (WEP), it directly implies equivalence between inertial and gravitational mass.
