我们检查了顶叶到达区（PRR）神经元在到达听觉或视觉刺激的记忆位置时的反应。我们发现 PRR 神经元的放电率包含有关听觉和视觉刺激位置的信息。对于用视觉刺激测试的神经元，信息量在整个任务中保持恒定。相比之下，对于用听觉刺激测试的神经元，目标位置信息的数量随着试验的进展而增加。在任务到达期间，听觉刺激测试的神经元携带的信息量与视觉刺激测试的神经元携带的信息量没有统计学差异。我们对这些数据的解释表明，PRR 神经元编码的信息类型在整个任务中不断演变。 NeuroReport 13:891-894 (C) 2002 Lippincott Williams Wilkins。
We examined the responses of neurons in the parietal reach region (PRR) during reaches to the remembered locations of auditory or visual stimuli. We found that the firing rate of PRR neurons contained information about the location of auditory and visual stimuli. For neurons tested with visual stimuli, the amount of information remained constant throughout the task. In contrast, for neurons tested with auditory stimuli, the amount of target-location information increased as the trial evolved. During the reach period of the task, the amount of information that was carried by neurons tested with auditory stimuli was not statistically different from the amount carried by neurons tested with visual stimuli. We interpret these data to suggest that the type of information that PRR neurons encode evolves throughout a task. NeuroReport 13:891-894 (C) 2002 Lippincott Williams Wilkins.
