Depth perception from moving cast shadow in macaque monkey

Saneyuki Mizutani, Nobuo Usui, Takanori Yokota, Masato Taira, more

Behavioural Brain Research > 2015 > 288 > Complete > 63-70

In the present study, we investigate whether the macaque monkey can perceive motion in depth using a moving cast shadow. To accomplish this, we conducted two experiments. In the first experiment, an adult Japanese monkey was trained in a motion discrimination task in depth by binocular disparity. A square was presented on the display so that it appeared with a binocular disparity of 0.12 degrees (initial...

Orthodontic Waves > 2015 > 74 > 1 > 10-14

To evaluate the effectiveness of cognitive behavioral therapy (CBT) for subjects with experimental orthodontic pain.Thirty-two healthy adult volunteers (mean age of 24.8 years) were recruited and randomized into two groups: CBT intervention group (CBT group; n=16) and no intervention group (control group; n=16). Subjects had no spaces in a row of teeth, and contact between the second bicuspid tooth...

Neural enhancement and attenuation induced by repetitive recall

Teruo Hashimoto, Nobuo Usui, Masato Taira, Shozo Kojima

Neurobiology of Learning and Memory > 2011 > 96 > 2 > 143-149

Learning is the process of accumulating information. Repetition can make the process of retrieving information more efficient. The mechanisms by which repetition facilitates the retrieval process, however, are not yet clear. Here, we used event-related functional magnetic resonance imaging to investigate the effects of repetition on cued recall. In this study, participants were asked to encode visually...

Perception of object motion in three-dimensional space induced by cast shadows

Narumi Katsuyama, Nobuo Usui, Izuru Nose, Masato Taira

NeuroImage > 2011 > 54 > 1 > 485-494

Cast shadows can be salient depth cues in three-dimensional (3D) vision. Using a motion illusion in which a ball is perceived to roll in depth on the bottom or to flow in the front plane depending on the slope of the trajectory of its cast shadow, we investigated cortical mechanisms underlying 3D vision based on cast shadows using fMRI techniques. When modified versions of the original illusion, in...

Cortical areas related to performance of WAIS Digit Symbol Test: A functional imaging study

Nobuo Usui, Tomoki Haji, Masakazu Maruyama, Narumi Katsuyama, more

Neuroscience Letters > 2009 > 463 > 1 > 1-5

Many neuropsychological studies have shown that the Digit Symbol Test (DST) of the Wechsler Adult Intelligence Scale (WAIS) is useful for screening for dysfunctions of the brain. However, it remains unclear which brain areas are actually involved in the performance of DST and what brain functions are used for executing this test. In this study, we examined the cortical areas related to cognitive aspects...

Is Broca's area involved in the processing of passive sentences? An event-related fMRI study

Satoru Yokoyama, Jobu Watanabe, Kazuki Iwata, Naho Ikuta, more

Neuropsychologia > 2007 > 45 > 5 > 989-996

We used functional magnetic resonance imaging (fMRI) to investigate whether activation in Broca's area is greater during the processing of passive versus active sentences in the brains of healthy subjects. Twenty Japanese native speakers performed a visual sentence comprehension task in which they were asked to read a visually presented sentence and to identify the agent or the patient in the sentence...

The neural mechanism associated with the processing of onomatopoeic sounds

Teruo Hashimoto, Nobuo Usui, Masato Taira, Izuru Nose, more

NeuroImage > 2006 > 31 > 4 > 1762-1770

This event-related fMRI study was conducted to examine the blood-oxygen-level-dependent responses to the processing of auditory onomatopoeic sounds. We used a sound categorization task in which the participants heard four types of stimuli: onomatopoeic sounds, nouns (verbal), animal (nonverbal) sounds, and pure tone/noise (control). By discriminating between the categories of target sounds (birds/nonbirds),...

Suspected sagittal sinus thrombosis in a patient receiving continuous ambulatory peritoneal dialysis

Jiro Arita, Tomohiro Gen, Yoichiro Nakae, Hiroshi Mochizuki, more

Brain and Development > 1995 > 17 > 6 > 446

The patient was a 14-year-old boy with chronic renal failure. He had been treated by continuous ambulatory peritoneal dialysis for 2 years.He developed the status of convulsions abruptly and had consciousness disturbance with spastic paralysis. Brain CT revealed low density areas on the bilateral parietal lobes. Therefore, we suspected him to have sagittal sinus thrombosis. He recovered rapidly...
