The model presents neurobiologically plausible accounts of sound recognition (including absolute pitch), neural plasticity involved in pitch, loudness and location information integration, and streaming and auditory recall. It is proposed that a cortical mechanism for sound identification modulates the spectrotemporal response fields of inferior colliculus neurons and regulates the encoding of the echoic trace in the thalamus. Identification involves correlation of sequential spectral slices of the stimulus-driven neural activity with stored representations in association with multimodal memories, verbal lexicons, and contextual information. Identities are then consolidated in auditory short-term memory and bound with attribute information (usually pitch, loudness, and direction) that has been integrated according to the identities' spectral properties. Attention to, or recall of, a particular identity will excite a particular sequence in the identification hierarchies and so lead to modulation of thalamus and inferior colliculus neural spectrotemporal response fields. This operates as an adaptive filter for identities, or their attributes, and explains many puzzling human auditory behaviors, such as the cocktail party effect, selective attention, and continuity illusions.
该模型提供了对声音识别（包括绝对音高）的神经生物学上合理的解释，包括涉及音高、响度和位置信息整合的神经可塑性，以及流和听觉回忆。该模型提出，用于声音识别的皮质机制调节下丘脑中神经元的频谱时域响应场，并调节丘脑回声的编码。识别涉及刺激驱动的神经活动的连续频谱片与与多模态记忆、词汇和上下文信息相关联的存储表示之间的相关性。然后，身份信息在听觉短期记忆中得到巩固，并与根据身份的频谱特性进行整合的属性信息（通常是音高、响度和方向）绑定。对特定身份的关注或回忆会激发识别层次结构中的特定序列，从而导致丘脑和下丘脑中的神经频谱时域响应场的调制。这作为身份或其属性的自适应滤波器运行，解释了许多令人困惑的人类听觉行为，例如鸡尾酒会效应、选择性注意和连续性错觉。
