Diffusion tensor imaging reveals sex differences in pain sensitivity of rats
Frontiers in Molecular Neuroscience, 2023 Studies on differences in brain structure and function according to sex are reported to contribute to differences in behavior and cognition. However, few studies have investigated brain structures or used tractography to investigate gender differences in

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery
Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

Abnormal connectional fingerprint in schizophrenia: a novel network analysis of diffusion tensor imaging data [PDF]
, 2016 The graph theoretical analysis of structural magnetic resonance imaging (MRI) data has received a great deal of interest in recent years to characterize the organizational principles of brain networks and their alterations in psychiatric disorders, such ...

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives Obsessive–compulsive disorder (OCD) is a psychiatric disorder with alterations of cortico‐striato‐thalamo‐cortical loops and impaired performance monitoring. Electrophysiological markers such as conflict‐related medial frontal theta (MFT) and error‐related negativity (ERN) may be altered by clinically effective deep brain ...

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives Central poststroke pain (CPSP), a neuropathic pain condition, is difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) targeted to the primary motor cortex (M1) can alleviate the condition, but not all patients respond. We aimed to assess a promising alternative rTMS target, the secondary somatosensory cortex (S2),

CTtrack: A CNN+Transformer-based framework for fiber orientation estimation & tractography
Neuroscience Informatics, 2022 In recent years, multiple data-driven fiber orientation distribution function (fODF) estimation algorithms and automatic tractography pipelines have been proposed to address the limitations of traditional methods. However, these approaches lack precision
