The role of the nucleus basalis prosencephali (Bas), a frontal forebrain structure peculiar to birds, in the control of forage pecking and apomorphine-induced pecking was investigated. In a quasi-natural grit-grain selection task bilateral coagulations of the Bas and the associated neostratum frontolaterale (Nfl) caused a marked fall in grain per peck uptake and a simultaneous increase in grit per peck uptake. Bas lesions also had a reducing effect on the compulsive pecking elicited by systemic injections of apomorphine. This confirms that the Bas is involved in the control of forage pecking and dopaminergic pecking of birds.
研究了鸟类特有的额叶前脑结构——前脑基底核（Bas）在控制觅食啄食和阿扑吗啡诱导的啄食中的作用。在一项类似自然的砂砾-谷物选择任务中，双侧损毁Bas和相关的额叶外侧新纹状体（Nfl）导致每次啄食摄取的谷物显著减少，同时每次啄食摄取的砂砾增加。Bas损伤对全身注射阿扑吗啡引起的强迫性啄食也有抑制作用。这证实了Bas参与了鸟类觅食啄食和多巴胺能啄食的控制。
