Quantitative Electroencephalographic Biomarkers for Repetitive Transcranial Magnetic Stimulation Treatment Response Prediction in Mild Cognitive Impairment: A Pilot Study Protocol for Multi‐Center, Assessor‐Blinded, Open‐Label Clinical Trial

Brain and Behavior, Volume 15, Issue 11, November 2025.
Repetitive transcranial magnetic stimulation (rTMS) enhances neural plasticity in mild cognitive impairment (MCI), but treatment success varies across individuals. In this pilot multicenter trial, quantitative EEG (QEEG) signals recorded before therapy are analyzed to identify predictors of clinical response.

From Speech Semantics to Brain Activity—Timescales Are Key in Their Information Transfer

Human Brain Mapping, Volume 46, Issue 16, November 2025.
We analyzed sentence similarity (SBERT) and word depth (WordNet) from the HCP 7 T MOVIE2_HO1.mp4 using dynamic ACW analysis. Brain activity in A1, TA2, and PSL regions was similarly analyzed. Transfer Entropy measured the information flow between semantic and brain timescales.

Wideband Millimeter‐Wave Balun‐Diplexer Based on a Novel Coupled Marchand Architecture for Compact Footprint and Phased‐Array Integration

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...

Precise Electrode Co‐Alignment in Deep Brain Stimulation Fusing Neuroimaging and Electrophysiology

European Journal of Neuroscience, Volume 62, Issue 10, November 2025.
ABSTRACT We present a multimodal framework to improve the precision of electrode placement in deep brain stimulation (DBS) by fusing preoperative neuroimaging with intraoperative electrophysiology for accurate electrode co‐alignment. The workflow integrates automated subthalamic nucleus (STN) segmentation from preoperative MRI using a two‐step ...

Enhancing CMRR in Fully Differential Amplifiers via Power Supply Bootstrapping

Chips
Fully differential amplifier circuits are well suited for instrumentation front ends and signal-conditioning applications. They offer high common-mode rejection ratios (CMRRs) regardless of the passive component tolerances but remain sensitive to ...

The Human Claustrum Activates Across Multiple Cognitive Control Tasks

European Journal of Neuroscience, Volume 62, Issue 9, November 2025.
We show that the claustrum activates during conditions and trial timepoints requiring increased cognitive demand, and this corresponds to activations in cortical networks consistent with goal‐directed task execution. These findings enhance our comprehension of the role of the claustrum in cognition.
