TL;DR: A multi-centre comparison of 17 mouse rsfMRI datasets via a common image processing and analysis pipeline is described, reporting the reproducible identification of several large-scale resting-state networks (RSN), including a mouse default-mode network, in the majority of datasets.
Journal ArticleDOI
Physiological effects of a habituation procedure for functional MRI in awake mice using a cryogenic radiofrequency probe
Keitaro Yoshida,Yu Mimura,Ryosuke Ishihara,Hiroshi Nishida,Yuji Komaki,Tomohito Minakuchi,Tomokazu Tsurugizawa,Masaru Mimura,Hideyuki Okano,Kenji F. Tanaka,Norio Takata,Norio Takata +11 more
TL;DR: This method developed head-fixation implements for awake mice that are applicable to fMRI using CryoProbe and would be beneficial for translational research using fMRI in mice and humans because human fMRI is typically performed without anesthetics.
Journal ArticleDOI
Optogenetic astrocyte activation evokes BOLD fMRI response with oxygen consumption without neuronal activity modulation.
Norio Takata,Norio Takata,Yuki Sugiura,Keitaro Yoshida,Miwako Koizumi,Nishida Hiroshi,Kurara Honda,Ryutaro Yano,Yuji Komaki,Ko Matsui,Makoto Suematsu,Masaru Mimura,Hideyuki Okano,Hideyuki Okano,Kenji F. Tanaka +14 more
TL;DR: In this paper, an astrocyte-evoked BOLD signal accompanied oxygen consumption without modulation of neuronal activity, which led to hypothesize the presence of another cellular source for Bold signal generation.
Journal ArticleDOI
Conditions for quantitative evaluation of injured spinal cord by in vivo diffusion tensor imaging and tractography: Preclinical longitudinal study in common marmosets
Tsunehiko Konomi,Kanehiro Fujiyoshi,Keigo Hikishima,Keigo Hikishima,Yuji Komaki,Yuji Komaki,Osahiko Tsuji,Hirotaka James Okano,Yoshiaki Toyama,Hideyuki Okano,Masaya Nakamura +10 more
TL;DR: Findings indicated that DTT analysis might be a versatile non-invasive tool for evaluating the axonal disruption after spinal cord injury (SCI).
Journal ArticleDOI
Diffusion tensor imaging and tractography of the spinal cord: from experimental studies to clinical application.
Kanehiro Fujiyoshi,Tsunehiko Konomi,Masayuki Yamada,Keigo Hikishima,Keigo Hikishima,Osahiko Tsuji,Yuji Komaki,Suketaka Momoshima,Yoshiaki Toyama,Masaya Nakamura,Hideyuki Okano +10 more
TL;DR: The basic principles of diffusion tensor imaging are outlined, the characteristics, limitations, and future uses of DTT to examine the spinal cord are described, and it is described that DTT is routinely performed of the human spinal cord in the clinic.
