The Development of Hippocampal‐Cortical Functional Connectivity in Infants and Toddlers

Human Brain Mapping, Volume 47, Issue 4, March 2026.
This study traces the early maturation of hippocampal‐cortical coupling along the hippocampal long‐axis across the first 2 years of life, revealing early increases with canonical memory regions followed by prolonged fine‐tuning with memory, salience, and attention networks. These developing interactions may support evolving long‐term memory capacity in

Comparison of ultrasensitive and mass spectrometry quantification of blood-based amyloid biomarkers for Alzheimer’s disease diagnosis in a memory clinic cohort

Alzheimer’s Research & Therapy, 2023
Background Alzheimer’s disease (AD) is a complex neurodegenerative disorder with β-amyloid pathology as a key underlying process. The relevance of cerebrospinal fluid (CSF) and brain imaging biomarkers is validated in clinical practice for early ...

High CMRR GaAs single-input to differential convertor

, 1996
In this paper a new topology for Single Input to Differential convertors is presented. Among the capabilities of convertors realised with this topology, 6 dB of extra conversion gain respect to a single differential cell and suppression of the common mode can be mentioned.

A Tree-Based Architecture for High-Performance Ultra-Low-Voltage Amplifiers

Journal of Low Power Electronics and Applications, 2022
In this paper, we introduce a novel tree-based architecture which allows the implementation of Ultra-Low-Voltage (ULV) amplifiers. The architecture exploits a body-driven input stage to guarantee a rail-to-rail input common mode range and body-diode ...

Enhanced ICMR amplifier for high CMRR biopotential recordings

2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019
This paper presents an integrated biopotential preamplifier architecture targeting applications that simultaneously require high common-mode rejection ratio (CMRR), low noise, high input common-mode range (ICMR), and current-efficiency (low Noise Efficiency Factor or NEF).

Current-Efficient Preamplifier Architecture for CMRR Sensitive Neural Recording Applications

IEEE Transactions on Biomedical Circuits and Systems, 2018
There are neural recording applications in which the amplitude of common-mode interfering signals is several orders of magnitude higher than the amplitude of the signals of interest. This challenging situation for neural amplifiers occurs, among other applications, in neural recordings of weakly electric fish or nerve activity recordings made with cuff

Rapid Nasal Breathing as a Biometric Trigger: High‐Accuracy Electroencephalogram‐Based Authentication for Clinical Applications

The Clinical Respiratory Journal, Volume 20, Issue 1, January 2026.
Our study demonstrates rapid nasal breathing‐evoked EEG signals enable high‐accuracy (98.3%) biometric authentication via a hybrid ResNet‐Swin Transformer model. This noninvasive approach eliminates external stimuli, offering secure patient identification for critical respiratory care settings, such as ventilator access and continuous monitoring ...

Quantifying multimodal longitudinal brain changes in presymptomatic C9orf72 disease

Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION The presymptomatic phase of frontotemporal dementia and amyotrophic lateral sclerosis associated with C9orf72 repeat expansion features widespread structural brain changes. We aimed at fulfilling the unmet need of quantitative magnetic resonance imaging (MRI)‐derived measures suitable for disease tracking.
