Working memory are closely related to everyday cognition (such as remembering the conversation and characters). Studies with hearing, vision stimulation have always been carried out, but studies using tactile stimulation are very little. However, tactile working memory is the ability to reproduce the functionality of the somatosensory system. It is very relevant to elucidation of the somatosensory system and intellectual impairment of tactile. Moreover, Visual and Auditory task have possibilities affect education and living environment, such as number, language and so on. On the other hand, tactile stimulation task can research human cognition without the problem. However, tactile stimulation is presented by hand, so study of tactile working memory does not consider pressure information and influence result. Moreover, Active region of brain is changed from time to time in working memory, it must be considered too. Memory in order to investigate the tactile working memory, device for considering the pressure information and to present the tactile stimulation on constant conditions is indispensable. In this Study, we developed and evaluated a device for tactile spatial research in high magnetic field environment. Consideration to advanced research on fMRI environment in the future, we developed device in High magnetic field environment.

In present paper, we described a novel wide-view visual presentation system for fMRI studies. To achieve a wide field view, a translucent spherical screen with a curvature radius of 30 mm was placed 30 mm away from the subjects' eyes. The subjects wore contact lenses that enabled them to focus on the screen, and the resulting visual field reached 120 degrees. Then, high resolution computer-generated images were projected onto the translucent hemispheric screen inside the MRI bore. Signal-to-noise ratio valuation experiment was performed to evaluate the clarity and quality of the MRI images. In addition, we successfully applied this visual presentation system to studies of visual retinotopic mapping and object perception neural function in the peripheral visual field. Our study demonstrated that the system is compatible with the MRI environment. Moreover, this system was more effective at mapping checkerboard stimuli in V1-V3, and successfully located several classical category-selective areas, including the face-selective area (FFA), occipital face area (OFA), house-selective area (PPA), transverse occipital sulcus (TOS), lateral occipital complex (LOC) in higher-level visual areas. In conclusion, the wide-view visual presentation system within the MRI environment can be applied to many kinds of fMRI studies of peripheral vision.

J024014 Tactile Working Memory Capacity in Elder and Young Subjects using N-back Task

Working memory has important role in daily life and a lot of research was done in visual or auditory information. However, tactile working memory was unclear indeed. So we did research for tactile working memory capacity using n-back task for young and elder subjects. The experimental stimulus was raised shape of four directions 'V'. The subjects recognized these shapes by index finger. Next, subjects compared the current stimuli with the n times back stimuli. Subjects then responded whether the direction of a stimulus is the same or different. As a result, there was a significant difference between young and elder subjects in accuracy. We presume that these results depend on aging effect of a working memory capacity and decline of the recognition capability. The next step to find property is measurement of brain activity for tactile n-back task.

Differential sensitivity for house pictographs and Chinese logographs in the 'parahippocampal place area'

Geqi Qi, Bin Wang, Satoshi Takahashi, Seiichiro Ohno, Susumu Kanazawa, Jinglong Wu

2013 ICME International Conference on Complex Medical Engineering, CME 2013 2013

Language：English

The 'parahippocampal place area, PPA' within parahippocampal cortex is generally implicated in perceiving the local visual environment. This region responds selectively and automatically in functional magnetic resonance imaging (fMRI) to house images. Previous studies have indicated that the house-selective response in the PPA can be explained by selectivity for low-level features of the visual stimuli, such as geometric structure and high special frequency (SF). However, it remains unclear which of the two visual features of stimuli contributes more to the house-selective response in the PPA. To address this issue, we compared the PPA response to house pictographs and Chinese logographs with two different levels of white noise. fMRI was used to record the subjects' PPA activation during category discrimination task between house and word. As a result, the PPA showed significant main effect of category but not noise level. The results suggest that the PPA is more tuned to geometrical structure of visual stimuli than their high SF features. © 2013 IEEE.
