Longitudinal MRI Characterization of T1 and T2 Relaxation Times in an Amyloid Mouse Model of Alzheimer's Disease at 11.7 T

open access: yesNMR in Biomedicine, Volume 39, Issue 1, January 2026.
In this study, we systematically characterized the longitudinal evolution of T1 and T2 relaxation times at the early to middle stage of Tg2576 mouse model representing the amyloidosis subtype of Alzheimer’s disease. We found that rates of change in relaxation times within the thalamus, hypothalamus, and piriform cortex may serve as markers for ...

Recursive Training of 2D-3D Convolutional Networks for Neuronal Boundary Detection

open access: yes, 2015
Efforts to automate the reconstruction of neural circuits from 3D electron microscopic (EM) brain images are critical for the field of connectomics. An important computation for reconstruction is the detection of neuronal boundaries.

A receptor-based analysis of local ecosystems in the human brain. [PDF]

open access: yes, 2017
BackgroundAs a complex system, the brain is a self-organizing entity that depends on local interactions among cells. Its regions (anatomically defined nuclei and areas) can be conceptualized as cellular ecosystems, but the similarity of their functional ...

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

open access: yesThe 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 ...

Spatial and temporal evolution of neuronal activation, stress and injury in lithium-pilocarpine seizures in adult rats. [PDF]

open access: yes, 1998
In order to follow the spatial and temporal evolution of neuronal damage, cellular activation and stress responses subsequent to lithium-pilocarpine seizures of various durations in the adult rat, we analyzed the expression of Fos protein and local ...
