Prediction of the information processing speed performance in multiple sclerosis using a machine learning approach in a large multicenter magnetic resonance imaging data set

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 186-202, January 2023., 2023
We developed an advanced machine learning pipeline to identify brain structural magnetic resonance imaging (MRI) volumes that, along with demographic and clinical data, predict information processing speed (IPS) performance, assessed with the Symbol Digit Modalities Test (SDMT), of patients with multiple sclerosis (MS).

Unraveling schizophrenia replicable functional connectivity disruption patterns across sites

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 156-169, January 2023., 2023
This study reported that ComBat harmonization was most robust in detecting aberrant connectivity while controlling for the false discoveries for schizophrenia. Besides, the identified three subnet‐specific composite functional connectivity measures might be considered replicable neuroimaging markers for schizophrenia.

The complexity of spontaneous brain activity changes in schizophrenia, bipolar disorder, and ADHD was examined using different variations of entropy

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 94-118, January 2023., 2023
The flowchart of the complexity of spontaneous brain activity by using multi‐types entropies. The raw rs‐fMRI images of the MSC dataset and UCLA dataset underwent preprocessing, time‐series extraction and then were used to compute entropy values using seven entropy methods.

MicroRNA binding site variation is enriched in psychiatric disorders

open access: yesHuman Mutation, Volume 43, Issue 12, Page 2153-2169, December 2022., 2022
Abstract Psychiatric disorders have a polygenic architecture, often associated with dozens or hundreds of independent genomic loci. Most associated loci impact noncoding regions of the genome, suggesting that the majority of disease heritability originates from the disruption of regulatory sequences.

下顎後方偏位時における前頭前野の賦活 [PDF]

open access: yes, 2016
The objective of this study was to evaluate occlusal condition by assessing brain activity in the prefrontal cortex, which is associated with emotion. Functional near-infrared spectroscopy (fNIRS) was used to detect changes in cerebral blood flow in the ...
