Journal ArticleDOI
Visual fatigue caused by stereoscopic images and the search for the requirement to prevent them: A review
TL;DR: The requirements to prevent visual fatigue and discomfort induced by viewing stereoscopic images were sought, and the careful alignment in the right/left eye images is required for the stereoscopic vision without discomfort.
Journal ArticleDOI
Target spatial frequency determines the response to conflicting defocus- and convergence-driven accommodative stimuli.
Yuuki Okada,Kazuhiko Ukai,James S. Wolffsohn,Bernard Gilmartin,Atsuhiko Iijima,Atsuhiko Iijima,Takehiko Bando +6 more
TL;DR: This is the first evidence that high-conflict conditions are a cause of asthenopia and specifically affect accommodative responses while viewing stereoscopic displays and it is proposed that defocus-driven accommodation becomes weak when the target comprises low spatial frequency components.
Journal ArticleDOI
Intrasulcal electrocorticography in macaque monkeys with minimally invasive neurosurgical protocols.

TL;DR: The novel methodology proposed here opens up a new frontier in neuroscience research, enabling the direct measurement and manipulation of electrical activity in the whole brain.
Journal ArticleDOI
Macaques Exhibit Implicit Gaze Bias Anticipating Others’ False-Belief-Driven Actions via Medial Prefrontal Cortex
Taketsugu Hayashi,Ryota Akikawa,Keisuke Kawasaki,Jun Egawa,Takafumi Minamimoto,Kazuto Kobayashi,Shigeki Kato,Yukiko Hori,Yuji Nagai,Atsuhiko Iijima,Atsuhiko Iijima,Toshiyuki Someya,Isao Hasegawa +12 more
TL;DR: It is found that neuronal activity in the medial prefrontal cortex could have a causal role in FB-attribution-like behaviors in the primate lineage, emphasizing the importance of probing the neuronal mechanisms underlying theory of mind with relevant macaque animal models.
Journal ArticleDOI
Re-evaluation of tropicamide in the pupillary response test for Alzheimer's disease.
Atsuhiko Iijima,Munetaka Haida,Norio Ishikawa,Akinori Ueno,Haruyuki Minamitani,Yukito Shinohara +5 more
TL;DR: It is found that non-AD subjects, including young subjects, showed the same extent of pupil dilation as AD subjects and the most effective cutoff point of 0.005% tropicamide for differential diagnosis was 114.5% of the average pupils dilation rate for 60 min.
