我们的目的是揭示什么是编码在国内小鸡的基底神经节。在水强化的“去”任务中，小鸡学会了有选择地啄一个彩色珠子，以获得一滴水。在获得的38个单位中，有7个单位特别在奖励期间表现出兴奋性活动。在食物强化去/不去的任务，小鸡学会了区分两种颜色，以获得糊状食物后延迟一段时间。他们还学会了忽略另一种与奖励无关的颜色。在获得的27个单位中，有4个单位在提示期内表现出兴奋性活动，特别是当预期食物奖励时。LPO神经元可能编码获得的奖励的质量，以及小鸡对即将到来的奖励的预期。NeuroReport 12：1431-1435（C）2001 Lippincott威廉姆斯和威尔金斯。
We aimed to reveal what is coded in the basal ganglia of domestic chicks. In the water-reinforced 'go' task, chicks learned to peck selectively at a colored bead in order to obtain a drop of water. Out of 38 units obtained, seven showed excitatory activities specifically during the reward period. In the food-reinforced go/no-go task, chicks learned to discriminate two colors to obtain mash food after a delay period. They also learned to ignore another color, which was not associated with a reward. Out of 27 units obtained, four showed excitatory activities during the cue period, specifically when a food reward was anticipated. LPO neurons may code qualities of the obtained rewards, and also chick's anticipation of the forthcoming rewards. NeuroReport 12:1431-1435 (C) 2001 Lippincott Williams & Wilkins.
