Bilateral Basal Ganglia Calcification: The Etiology and Clinical Findings of 17 Patients

open access: yesTürk Nöroloji Dergisi, 2009
OBJECTIVE: Bilateral basal ganglia calcification is a rare disease with symmetrical and bilateral deposition of calcium and other minerals in the basal ganglia, cerebellum, dentate nucleus, and white matter. Clinical findings are variable and can present

Neural electrodes for brain‐computer interface system: From rigid to soft

open access: yesBMEMat, EarlyView.
Here, we review the development trends of neural electrodes in BCI. This paper highlights the critical role of electrodes in BCI systems, analyzes the limitations of rigid electrodes, and introduces various flexible electrodes. Furthermore, we discuss application scenarios and prospects of BCI electrode technology, aiming to provide valuable references

Control of Functional Connectivity in Cerebral Cortex by Basal Ganglia Mediated Synchronization [PDF]

open access: yesarXiv, 2017
Since the earliest electroencephalography experiments, large scale oscillations have been observed in the mammalian brain. More recently, they have been identified not only in the cerebral cortex and thalamus, but pervasively in the healthy basal ganglia.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

open access: yesBMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

A probabilistic atlas of the human thalamic nuclei combining ex vivo MRI and histology [PDF]

open access: yesarXiv, 2018
The human thalamus is a brain structure that comprises numerous, highly specific nuclei. Since these nuclei are known to have different functions and to be connected to different areas of the cerebral cortex, it is of great interest for the neuroimaging community to study their volume, shape and connectivity in vivo with MRI.

Coordinate Network Mapping of Focal Brain Volume Differences in ADHD Reveals Common Patterns That Lack Specificity: A Systematic Review

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Objective Attention‐deficit/hyperactivity disorder (ADHD) has been associated with decreased regional brain volume, yet no consistent localization has emerged across studies. This discrepancy has been attributed to ADHD's diagnostic heterogeneity; however, one alternative is that ADHD is associated with alterations of brain networks, not ...

Learning Hierarchical Information Flow with Recurrent Neural Modules [PDF]

open access: yesarXiv, 2017
We propose ThalNet, a deep learning model inspired by neocortical communication via the thalamus. Our model consists of recurrent neural modules that send features through a routing center, endowing the modules with the flexibility to share features over multiple time steps.
