Pigeons were trained to detect auditory and vibratory stimuli in two separate experiments using an instrumental conditioning procedure. The discriminative stimuli became effective as the subjects grasped a probe with the beak. The pigeons learned to suppress responding upon this grasp-contingent stimulation. Bilateral lesions of the nucleus basalis prosencephali (Bas), known to be involved in the motor control of pecking and to receive short latency input of cochlear and trigeminal origin, eliminated the behavioral stimulus detection. The performance of a control color discrimination was not affected by the Bas lesions, demonstrating that these had a specific effect. The processing of peck-related feedback by the nucleus basalis during the normal food uptake of pigeons is discussed.
在两项独立实验中，利用工具性条件反射程序训练鸽子检测听觉和振动刺激。当鸽子用喙抓住探针时，辨别性刺激开始起作用。鸽子学会在这种与抓握相关的刺激下抑制反应。已知参与啄食运动控制并接收来自耳蜗和三叉神经起源的短潜伏期输入的前脑基底核（Bas）双侧损伤，消除了行为刺激检测。对照颜色辨别任务的表现不受Bas损伤的影响，表明这些损伤具有特定作用。本文讨论了鸽子正常进食过程中基底核对与啄食相关反馈的处理。
