鹦鹉和鸣鸟从同种导师那里学习发声，就像人类婴儿获得口语一样。鹦鹉可以学习人类的语言，有人认为它们可以用它们来与人类交流。鹦鹉脑中的尾内侧软腭与鸣禽的类似，类似于人类的听觉联合皮层，参与语音处理。在这里，我们研究了神经元的激活，立即早期基因ZENK的蛋白质产物的表达，在听觉学习的虎皮鹦鹉（Melopsittacus undulatus），鹦鹉。雄性虎皮鹦鹉成功地学会了区分另一个雄性同种所说的两个日语单词。再次暴露于这两个discriminanda导致增加神经元激活的尾内侧palaleums，但不是在海马体，相比未经训练的鸟类，暴露于相同的话，或没有暴露的话。实验鸟尾内侧腭板神经元的激活与辨别任务中正确反应的百分比显著正相关。这些结果表明，鹦鹉的尾内侧大脑皮层参与了听觉学习。因此，在鹦鹉、鸣禽和人类中，类似的大脑区域可能包含听觉学习和记忆的神经基质。
Parrots and songbirds learn their vocalizations from a conspecific tutor, much like human infants acquire spoken language. Parrots can learn human words and it has been suggested that they can use them to communicate with humans. The caudomedial pallium in the parrot brain is homologous with that of songbirds, and analogous to the human auditory association cortex, involved in speech processing. Here we investigated neuronal activation, measured as expression of the protein product of the immediate early gene ZENK, in relation to auditory learning in the budgerigar (Melopsittacus undulatus), a parrot. Budgerigar males successfully learned to discriminate two Japanese words spoken by another male conspecific. Re-exposure to the two discriminanda led to increased neuronal activation in the caudomedial pallium, but not in the hippocampus, compared to untrained birds that were exposed to the same words, or were not exposed to words. Neuronal activation in the caudomedial pallium of the experimental birds was correlated significantly and positively with the percentage of correct responses in the discrimination task. These results suggest that in a parrot, the caudomedial pallium is involved in auditory learning. Thus, in parrots, songbirds and humans, analogous brain regions may contain the neural substrate for auditory learning and memory.
