本综述指出无尾动物的视运动功能是可改变的，并提供提示前脑调节功能的神经生理学数据。视网膜-tecto/被盖-球髓/脊髓序列处理流在捕食行为的刺激-反应调解中是足够的。然而，如果没有它与前脑结构的调节连接，这些处理流就不能管理感知任务、定向注意力、学习表现和运动技能。(1)视觉上的猎物/非猎物区分是基于这一加工流与前额丘脑的相互作用，涉及神经递质神经肽- y。(2)多巴胺激动剂阿波啡结合2DG作图和单神经元记录的实验表明，捕食和等待猎物的捕捉策略依赖于视网膜、前顶盖、基底神经节、边缘和中边缘结构参与的神经宏观网络中的剂量依赖性多巴胺能调节。(3)纹状体输出神经元的视觉反应特性支持腹侧纹状体参与定向注意的观点。(4)包括腹侧内侧苍白质在内的各种调节回路在视觉或视觉嗅觉学习（联想学习）过程中改变猎物识别，或负责刺激特异性习惯化（非联想学习）。(5)神经宏观网络的标准方案强调了前脑调节功能的基础电路。这些为将来的决定性实验提供了合适的概念。(C) 2001爱思唯尔科学公司版权所有。
The present review points out that visuomotor functions in anurans are modifiable and provides neurophysiological data which suggest modulatory forebrain functions. The retino-tecto/tegmento-bulbar/spinal serial processing streams are sufficient for stimulus-response mediation in prey-catching behaviour. Without its modulatory connections to forebrain structures, however, these processing streams cannot manage perceptual tasks, directed attention, learning performances, and motor skills. (1) Visual prey/non-prey discrimination is based on the interaction of this processing stream with the pretectal thalamus involving the neurotransmitter neuropeptide-Y. (2) Experiments applying the dopamine agonist apomorphine in combination with 2DG mapping and single neurone recording suggest that prey-catching strategies in terms of hunting prey and waiting for prey depend on dose dependent dopaminergic adjustments in the neural macronetwork in which retinal, pretecto-tectal, basal ganglionic, limbic, and mesolimbic structures participate. (3) Visual response properties of striatal efferent neurones support the concept that ventral striatum is involved in directed attention. (4) Various modulatory loops involving the ventral medial pallium modify prey-recognition in the course of visual or visual-olfactory learning (associative learning) or are responsible for stimulus-specific habituation (non-associative learning). (5) The circuits suggested to underlie modulatory forebrain functions are accentuated in standard schemes of the neural macronetwork. These provide concepts suitable for future decisive experiments.
