A recent report demonstrated that, while fixating a central light, lateral intraparietal area (LIP) neurons are not modulated by the location of auditory stimuli until monkeys learn to saccade to the location of an auditory stimulus. This finding suggests that auditory spatial responses in area LIP are dependent on auditory-saccadic training. We found that, in monkeys that had not been trained to make behavioral responses to auditory stimuli, LIP neurons are modulated by auditory-stimulus location when a central light is not present in the environment. These results indicate that LIP auditory responses are not wholly dependent on behavioral training with auditory stimuli.
最近的一份报告表明，当注视中央光点时，直到猴子学会向听觉刺激的位置进行扫视，顶内沟外侧区（LIP）神经元才会受到听觉刺激位置的调节。这一发现表明，LIP区的听觉空间反应依赖于听觉-扫视训练。我们发现，在尚未训练对听觉刺激做出行为反应的猴子中，当环境中不存在中央光点时，LIP神经元会受到听觉刺激位置的调节。这些结果表明，LIP的听觉反应并不完全依赖于对听觉刺激的行为训练。
