Learning and Visual Hallucination
It is generally recognized that learning is a useful tool for solving vision problems. However, at present time, neither learning nor vision is a well understood problem. It is even less clear how one might be able to put the two together. In this paper I will attempt to study one small aspect of this problem of using learning in vision. In particular I will study how learning might be used for...
متن کاملVisual Hallucination For Computational Creation
Research on computational painters usually focuses on simulating rational parts of the generative process. From an art-historic perspective it is plausible to assume that also an arational process, namely visual hallucination, played an important role in modern fine art movements like Surrealism. The present work investigates this connection between creativity and hallucination. Using psycholog...
متن کاملTransient cortical excitation at the onset of visual fixation.
Primates actively examine the visual world by rapidly shifting gaze (fixation) over the elements in a scene. Despite this fact, we typically study vision by presenting stimuli with gaze held constant. To better understand the dynamics of natural vision, we examined how the onset of visual fixation affects ongoing neuronal activity in the absence of visual stimulation. We used multiunit activity...
متن کاملthe role of visual aids and translation in teaching vocabulary in est
the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...
15 صفحه اولAction of brain-derived neurotrophic factor on function and morphology of visual cortical neurons
Brain-derived neurotrophic factor (BDNF) is known to play a role in experience-dependent plasticity of the developing visual cortex. For example, BDNF acutely enhances long-term potentiation and blocks long-term depression in the visual cortex of young rats. Such acute actions of BDNF suggested to be mediated mainly through presynaptic mechanisms. A chronic application of BDNF to the visual cor...
