Abstract
Previous microelectrode recordings in the putamen of monkeys have revealed a class of tonically active neurons without apparent behavioral correlates. The present study shows that such neurons have responses to stimuli that trigger movement but that these responses disappear when motor responses to the stimuli are extinguished. The short latency of the responses (less than for other putamen neurons) suggests that they may play a role in linking conditioned stimuli and responses.
摘要
先前在猴子壳核中的微电极记录显示，存在一类持续活动的神经元，它们与明显的行为并无关联。本研究表明，这类神经元对触发运动的刺激有反应，但当对这些刺激的运动反应被消除时，这些反应就会消失。这些反应的潜伏期较短（比其他壳核神经元的潜伏期短），这表明它们可能在将条件刺激与反应联系起来方面发挥作用。
