Bilateral lesions of the nucleus accumbens in cat elicited the following changes: preservation in tests requiring focused attention, with difficulty to shift to other targets; paucity of movements, animals displaying moderate hypokinesia and loss of reaction to changes in the environment. These symptoms were accompanied by a significant increase in the amount of beta rhythms, an activity that has been shown to be concomitant with the development of focused attentive behavior. The observed behavioral and electrocortical modifications are opposite those that have been previously obtained in the same species after lesions of the ventral tegmental area.
在需要集中注意力的测试中表现正常，但难以转移到其他目标；运动减少，动物表现出中度运动迟缓以及对环境变化失去反应。这些症状伴随着β节律数量的显著增加，这种活动已被证明与集中注意力行为的发展相伴。观察到的行为和皮层电活动变化与之前在同一物种中腹侧被盖区损伤后所获得的变化相反。
