Abstract

Avian nidopallium caudolaterale (NCL), a functional analogue of mammalian prefrontal cortex, is thought to be participated to goal-directed behavior. However, few studies so far investigated local field potential (LFP) properties within this area. In this study, we recorded the LFP activity from the NCL of six pigeons when they performed a goal-directed decision-making task in a plus-maze. Spectral analysis revealed a significant LFP-power increase in the gamma-band (40-60Hz) during the decision-making process. Moreover, the LFP activity in the gamma-band was modulated by the behavioral outcomes of pigeons. It could decode effectively the motion directions of animals. These results indicate that the gamma rhythm of LFP recorded from the NCL correlates with the goal-directed behavior of pigeons.

摘要

禽类尾侧苍白球（NCL）被认为参与了目标导向行为，它是哺乳动物前额叶皮层的功能类似物。然而，到目前为止，很少有研究调查该区域内的局部场电位（LFP）特性。在这项研究中，当六只鸽子在正字迷宫中执行目标导向决策任务时，我们记录了它们 NCL 的 LFP 活动。频谱分析显示，在决策过程中，伽马波段（40-60Hz）的 LFP 功率显著增加。此外，LFP 在伽马波段的活动被鸽子的行为结果所调制。它可以有效地解码动物的运动方向。这些结果表明，从 NCL 记录的 LFP 伽马节律与鸽子的目标导向行为相关。
