Functional specialization is a common characteristic of the cerebral cortex. Globally, regions are specialized to perform particular sensory or motor functions. Within extrastriate visual cortex of humans, monkeys and cats, areas have been identified that are further specialized for spatial, motion, and pattern processing. The behavioural correlate for such functional specializations, or a “division of labour”, within auditory cortex is largely unknown. The long-term goal of our research program is to elucidate the behavioral “division of labour” within cat auditory cortex and determine the relative contributions that the different auditory fields make to acoustically-mediated behaviors. These results, when combined with investigations of underlying neuronal activity and cerebral connections, will provide evidence for, or refute, which hierarchical or network theories best explain processing in auditory cortex.

功能特化是大脑皮层的一个共同特征。在全球范围内，区域专门执行特定的感觉或运动功能。在人类、猴子和猫的纹外视觉皮质内，已经发现了进一步专门用于空间、运动和模式处理的区域。听觉皮层内这种功能性专门化或“劳动分工”的行为相关性在很大程度上是未知的。我们的研究计划的长期目标是阐明猫听觉皮层内的行为“分工”，并确定不同的听觉场对听觉介导的行为的相对贡献。这些结果，当结合调查潜在的神经元活动和大脑连接，将提供证据，或反驳，层次或网络理论最好地解释在听觉皮层的处理。
