    Neural correlates for perception of 3D surface orientation from texture gradient (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-10-12
    Description: A goal in visual neuroscience is to reveal how the visual system reconstructs the three-dimensional (3D) representation of the world from two-dimensional retinal images. Although the importance of texture gradient cues in the process of 3D vision has been pointed out, most studies concentrate on the neural process based on binocular disparity. We report the neural correlates of depth perception from texture gradient in the cortex. In the caudal part of the lateral bank of intraparietal sulcus, many neurons were selective to 3D surface orientation defined by texture gradient, and their response was invariant over different types of texture pattern. Most of these neurons were also sensitive to a disparity gradient, suggesting that they integrate texture and disparity gradient signals to construct a generalized representation of 3D surface orientation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsutsui, Ken-Ichiro -- Sakata, Hideo -- Naganuma, Tomoka -- Taira, Masato -- New York, N.Y. -- Science. 2002 Oct 11;298(5592):409-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Nihon University School of Medicine, Tokyo 173-8610, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12376700" target="_blank"〉PubMed〈/a〉

    Cognitive neurophysiology of the motor cortex (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-04-02
    Description: A major challenge of current neuroscience is to elucidate the brain mechanisms that underlie cognitive function. There is no doubt that cognitive processing in the brain engages large populations of cells. This article explores the logic of investigating these problems by combining psychological studies in human subjects and neurophysiological studies of neuronal populations in the motor cortex of behaving monkeys. The results obtained show that time-varying psychological processes can be visualized in the time-varying activity of neuronal populations. Moreover, the functional interactions between cells in the motor cortex are very similar to those observed in a massively interconnected artificial network performing the same computation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Georgopoulos, A P -- Taira, M -- Lukashin, A -- NS17413/NS/NINDS NIH HHS/ -- PSMH48185/PS/NCHHSTP CDC HHS/ -- New York, N.Y. -- Science. 1993 Apr 2;260(5104):47-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉American Legion, Minneapolis, MN.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8465199" target="_blank"〉PubMed〈/a〉

    The motor cortex and the coding of force (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-06-19
    Description: The relation of cellular activity in the motor cortex to the direction of two-dimensional isometric force was investigated under dynamic conditions in monkeys. A task was designed so that three force variables were dissociated: the force exerted by the subject, the net force, and the change in force. Recordings of neuronal activity in the motor cortex revealed that the activity of single cells was directionally tuned and that this tuning was invariant across different directions of a bias force. Cell activity was not related to the direction of force exerted by the subject, which changed drastically as the bias force changed. In contrast, the direction of net force, the direction of force change, and the visually instructed direction all remained quite invariant and congruent and could be the directional variables, alone or in combination, to which cell activity might relate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Georgopoulos, A P -- Ashe, J -- Smyrnis, N -- Taira, M -- NS07226/NS/NINDS NIH HHS/ -- NS17413/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1992 Jun 19;256(5064):1692-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brain Sciences Center, Department of Veterans Affairs Medical Center, Minneapolis, MN 55455.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1609282" target="_blank"〉PubMed〈/a〉
