Local field potential oscillations induced by goal-directed behavior of pigeon

In mammals, prefrontal cortex (PFC) plays an important role in goal-directed navigation task. The avian nidopallium caudolaterale (NCL) and the mammalian PFC are similar in many aspects, such as anatomical connectivity, functional characteristics, and so on. However, it is unclear that whether the avian NCL plays the same or similar role in the goal-directed navigation. In this study, based on the plus-maze device, we recorded and analyzed local field potential (LFP) signals in the NCL when the pigeons performed a goal-directed decision-making task. And the LFP properties in the NCL during the goal-directed behavior of pigeons were studied. The results have shown that the LFP power in gamma-band (40–60 Hz) has significantly difference between the turning begin and the turning end. Moreover, it can effectively decode the behavioral outcomes of pigeons (i.e., the left-turning, the forward, and the right-turning). These results imply that the NCL may be an important brain region for the goal-directed navigation of pigeons.
