In the present study, we investigated whether rats (Rattus norvegicus) could be trained to use tools in an experimental setting. In Experiment 1, we investigated whether rats became able to choose appropriate hook-shaped tools to obtain food based on the spatial arrangements of the tool and food, similar to tests conducted in non-human primates and birds.(More)
Previous studies have reported that lesions of the orbitofrontal cortex (OFC) in rats induce impulsive choices in delayed reinforcement tasks. However, some studies have suggested that the OFC is not related to impulsivity but instead to compulsivity. In this study, we investigated the effects of OFC lesions on choice in a T-maze. First, 14 rats were(More)
Tool-use behaviour has been observed in nonhuman animals in the wild and in experimental settings. In the present study, we investigated whether rats (Rattus norvegicus) could manipulate a tool according to the position of food to obtain the food in an experimental setting. Eight rats were trained to use a rake-shaped tool to obtain food beyond their reach(More)
