Overview

Yasumasa Okamoto is a researcher affiliated with Hiroshima University in Japan. Their work spans several interconnected fields, primarily focusing on Neuroscience, Medicine, and Psychology. Within these domains, their research often explores subfields such as Cognitive Neuroscience, Experimental and Cognitive Psychology, Radiology, Nuclear Medicine and Imaging, Biological Psychiatry, and Physiology.

The main topics of Okamoto's research include Functional Brain Connectivity Studies, Mental Health Research Topics, Neural dynamics and brain function, Advanced Neuroimaging Techniques and Applications, Advanced MRI Techniques and Applications, Tryptophan and brain disorders, and EEG and Brain-Computer Interfaces.

Key recent publications by Okamoto and collaborators demonstrate a focus on brain imaging and mental health disorders. These include:

  • "A multi-site, multi-disorder resting-state magnetic resonance image database" (2021), published in Scientific Data
  • "Generalizable brain network markers of major depressive disorder across multiple imaging sites" (2020), published in PLoS Biology
  • "Kynurenic acid is a potential overlapped biomarker between diagnosis and treatment response for depression from metabolome analysis" (2020), published in Scientific Reports
  • "Primary functional brain connections associated with melancholic major depressive disorder and modulation by antidepressants" (2020), published in Scientific Reports
  • "Brain/MINDS beyond human brain MRI project: A protocol for multi-level harmonization across brain disorders throughout the lifespan" (2021), published in NeuroImage Clinical

Okamoto frequently publishes in specific scientific venues, contributing multiple papers to:

  • Scientific Reports
  • Molecular Psychiatry
  • bioRxiv (Cold Spring Harbor Laboratory)
  • Psychiatry and Clinical Neurosciences
  • Research Square (Research Square)

Collaboration is an important aspect of Okamoto's work. Frequent co-authors include:

  • Go Okada (49 coauthored papers)
  • Masahiro Takamura (34 coauthored papers)
  • Mitsuo Kawato (24 coauthored papers)
  • Kiyoto Kasai (23 coauthored papers)
  • Naho Ichikawa (21 coauthored papers)

The research carried out by Okamoto combines advanced neuroimaging methodologies with clinical and cognitive perspectives. The focus on mental health, particularly mood disorders such as major depressive disorder, aligns with their contributions to identifying potential biomarkers and brain network markers through multi-site neuroimaging datasets.

Their work supports harmonization efforts across diverse imaging sites and disorders, aiming to standardize protocols and improve data reliability in brain disorder studies throughout the lifespan.
