Abstract

The interaction of listening to words and watching sign language in short-term and long-term cochlear implant (CI) users who have learned sign language after becoming deaf was measured using PET. In short-term CI users the auditory cortex was inactive while in long-term CI users it was fully activated with the simultaneous presentation of auditory and visual input. The result suggests the possibility that the interference of rival modalities may be diminished with experience and the preference switchover from the visual input to the auditory input could be accomplished by means of the neural plasticity persisting in the mature human auditory cortex.

利用PET检测短期和长期人工耳蜗使用者的神经可塑性。

用PET测量了短期和长期人工耳蜗使用者在失聪后学习手语的听词和看手语的相互作用。短期CI使用者的听觉皮层不活跃，而长期CI使用者的听觉皮层在听觉和视觉输入同时呈现时完全激活。结果表明，竞争模态的干扰可能随着经验的增加而减少，从视觉输入到听觉输入的偏好转换可能是通过成熟的人听觉皮层中持续存在的神经可塑性来完成的。

期刊介绍： NeuroReport is a channel for rapid communication of new findings in neuroscience. It is a forum for the publication of short but complete reports of important studies that require very fast publication. Papers are accepted on the basis of the novelty of their finding, on their significance for neuroscience and on a clear need for rapid publication. Preliminary communications are not suitable for the Journal. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool. The core interest of the Journal is on studies that cast light on how the brain (and the whole of the nervous system) works. We aim to give authors a decision on their submission within 2-5 weeks, and all accepted articles appear in the next issue to press.
