Brain activation during the fist-edge-palm test: a functional MRI study (2002)
Umetsu, A., Okuda, J., Fujii, T., Tsukiura, T., Nagasaka, T., Yanagawa, I., ...
The purpose of our study is to clarify, using functional MRI, brain regions activated during the fist-edge-palm task (FEP) compared to relatively simple hand motor tasks using either the right or the...
Fujii, T., Okuda, J., Tsukiura, T., Ohtake, H., Miura, R., Fukatsu, R., ...
Human lesion data indicate that the basal forebrain or orbitofrontal cortex, or both, as well as medial temporal and diencephalic structures, is important for normal memory and that its disruption...
Tsukiura, T., Fujii, T., Fukatsu, R., Otsuki, T., Okuda, J., Umetsu, A., ...
The aim of this study was to identify the neuroanatomical basis of the retrieval of people's names. Lesion data showed that patients with language-dominant temporal lobectomy had impairments in their...
Tsukiura, T., Fujii, T., Takahashi, T., Xiao, R., Inase, M., Iijima, T., ...
We used functional magnetic resonance imaging (fMRI) to investigate neural correlates of processes concerning store and manipulation in verbal working memory. We prepared a revised lag 1 digit span,...
Judging semantic and episodic incongruity: a magnetoencephalographic study (2001)
Suzuki, K., Okuda, J., Otsuka, Y., Sugawara, A., Hatanaka, K., Nakasato, N., ...
Evoked magnetic fields over the entire head were measured during a semantic judgment task, in which conditions of the pre-test learning session were manipulated. Subjects learnt related and unrelated...
