HEMISPHERIC SPECIALIZATION IN VISION AND AUDITION

描述：本提案中检验的主要假设是， 左半球专门处理高频刺激， 视觉和听觉，右半球专门负责 处理两种模式下的低频刺激。 半球 提出了视觉中不同空间频率的特化 调查人员和他的合作者提供了 证据表明，一个平行的专业化可能存在的声音频率。 这一建议进一步探讨了不对称半球的性质， 高频和低频信息专业化， 通过检查正常受试者的听觉不对称性， （实验1和2），听觉和视觉不对称的患者， 局灶性病变（实验3和4），正常对照组的跨模态比较 受试者（实验5，6和7），和听觉不对称的讲话 正常组和患者组的感知（实验8-11）。 此外，本发明还提供了一种方法， 视觉和听觉半球不对称的联结主义模型 本文提出

DESCRIPTION: The main hypothesis examined in this proposal is that the left hemisphere is specialized for processing high-frequency stimuli in vision and in audition, and that the right hemisphere is specialized for processing low-frequency stimuli in both modalities. Hemispheric specialization for different spatial frequencies in vision was proposed by Sergent, and the investigator and his collaborators have provided evidence that a parallel specialization may exit for sound frequencies. This proposal further examines the nature of asymmetric hemispheric specialization for high-frequency and low-frequency information in audition & in vision by examining auditory asymmetries in normal subjects (Experiments 1 and 2), auditory and visual asymmetries in patients with focal lesions (Experiments 3 and 4), crossmodal comparisons in normal subjects (Experiments 5, 6 and 7), and auditory asymmetries for speech perception in normal and patient groups (Experiments 8-11). In addition, a connectionist model of hemispheric asymmetries in vision and audition is proposed.
