声音交流是在社会影响下发展起来的，它可以增强注意力，这是记忆形成和知觉调节的重要因素。在鸣禽中，社会条件可以延迟敏感时期的发展，克服学习抑制，使特殊学习或诱导选择性学习。然而，我们不知道社会环境是如何影响大脑中的听觉处理的。本研究在不同社会条件下饲养幼年椋鸟，在相同的成人歌曲听觉体验下，比较不同社会条件对听觉皮层类似物发育的影响。社会经验影响了听觉神经元位点的比例和神经元的选择性。与成人模型的身体和社会隔离改变了听觉区域的发展，同时也改变了声音发展。据我们所知，这是第一个证明社会剥夺对神经元反应的影响与感觉剥夺一样大的证据。
Vocal communication develops under social influences that can enhance attention, an important factor in memory formation and perceptual tuning. In songbirds, social conditions can delay sensitive periods of development, overcome learning inhibitions and enable exceptional learning or induce selective learning. However, we do not know how social conditions influence auditory processing in the brain. In the present study, we raised young naive starlings under different social conditions but with the same auditory experience of adult songs, and we compared the effects of these different conditions on the development of the auditory cortex analogue. Several features appeared to be influenced by the social experience, among which the proportion of auditory neuronal sites and the neuronal selectivity. Both physical and social isolation from adult models altered the development of the auditory area in parallel to alterations in vocal development. To our knowledge, this is the first evidence that social deprivation has as much influence on neuronal responsiveness as sensory deprivation.
