IEICE technical report. Neurocomputing   111(96) 61-66   Jun 2011
Two eye movements are involved in the ocular tracking of a moving visual target. One is a fast and ballistic eye movement, referred to as saccade, which brings the retinal image of the visual target onto the fovea, and another is a slow and smooth...

複数の妨害刺激の中で 1 つだけ色が異なる目標刺激があると目立ち (視覚的顕在性が高く),我々の注意を自動的に惹きつける.視覚的顕在性の程度は目標刺激と妨害刺激の色コントラストだけでなく各刺激の背景との輝度コントラストにも依存する.我々はこれら二つのコントラストを組み合わせて,視覚的特徴は全く異なるがサッカード眼球運動潜時が同程度 (視覚的顕在性が同程度) の 2 種類のアレイ刺激を作成し,視覚探索課題を遂行しているサルの後頭頂葉からニューロン活動を記録した.その結果,同一のサッカード眼球...

IEICE technical report. Neurocomputing   108(130) 1-6   Jul 2008
An object differing from its surrounding objects in basic feature dimensions is salient and automatically draws our attention. In theoretical models of visual search or attention, information on stimulus features is separately computed in parallel...
ITEJ Technical Report   20(59) 31-36   Nov 1996
The main purpose of the present study was to investigate adaptive properties in human smooth-pursuit eye movements generated by a peripheral moving target. In adaptation trials, a target appeared in the peripheral visual field and immediately move...

IEICE technical report. Neurocomputing   95(389) 61-68   Nov 1995
In the present work we studied adaptive properties in open-loop pursuit eye movements. Some properties were found in the pursuit adaptation system. positional selectivity: the pursuit adaptation system could give different pursuit gains (pursuit v...

Project Year: 2008 - 2010    Investigator(s): Tadashi OGAWA
We found that a subset of neurons in the posterior parietal cortex (PPC) significantly discriminated the target from other stimuli only when the target was defined by a particular stimulus dimension and had specific stimulus features, such as a sh...

Project Year: 2004 - 2008    Investigator(s): Kenji KAWANO
To investigate the information processing in the brain during visual tracking eye movements, we exposed various moving visual stimuli to human subjects, monkeys and mice, and analyzed their ocular responses. For a further understanding, we recorde...

Project Year: 2002 - 2005    Investigator(s): Minami ITO
This study aimed at revealing the neuronal mechanisms representing angles embedded within contour stimuli in the early visual stages. First, we recorded from the superficial layer of area V2, while monkeys performed the fixation task. Stimuli were...

Discrimination and categorization are two different aspects of our color vision. On the one hand, we can discriminate subtle difference in color; on the other hand, we categorize similar colors into a single group such as 'red'. To study the effec...
