一个受生物学启发的认知架构必须从动物（包括人类）的认知中汲取灵感。这样的架构应该忠实地模拟认知神经科学的高级模块和过程。此外，生物启发的认知架构预计将有助于BICA“创造一个现实生活中的计算相当于人类思维的挑战”。全球工作空间理论（GWT）是一种统一的认知理论，已成为关于意识在认知中的作用的最广泛接受、最有经验支持的理论。最近的实验研究揭示了丰富的皮层连接能够支持一个大规模的动态网络。我们提出，大脑实际上是循环和动态地形成这样一个网络，根据GWT。受生物学启发的利达认知架构在概念上和计算上实现了GWT。在这里，我们认为，利达架构的广度，灵活的动机使用的感觉，明确的注意力机制，以及持续的，增量的和在线学习的几种方式提供了一个重要的第一步，BICA的挑战的方向。我们还测量了利达对BICA表中所列的实现认知架构的架构功能。应用最近的大脑连接的结果，我们继续阐明利达和潜在的和激励神经科学之间的关系，使用非线性动力学的语言。特别是，我们声称，利达的表示对应于流域的吸引力的非线性动力学的神经激活模式。此外，我们声称，节奏的利达的认知周期和其内部的认知元素有明确的心理生理学推论的振荡模式中观察到的人类大脑。(C)2012爱思唯尔有限公司版权所有。
A biologically inspired cognitive architecture must draw its insights from what is known from animal (including human) cognition. Such architectures should faithfully model the high-level modules and processes of cognitive neuroscience. Also, biologically inspired cognitive architectures are expected to contribute to the BICA "challenge of creating a real-life computational equivalent of the human mind". One unified theory of cognition, Global Workspace Theory (GWT) has emerged as the most widely accepted, empirically supported theory of the role of consciousness in cognition. Recent experimental studies reveal rich cortical connectivity capable of supporting a large-scale dynamic network. We propose that brains in fact cyclically and dynamically form such a network according to GWT. The biologically inspired LIDA cognitive architecture implements GWT conceptually and computationally. Here we argue that the LIDA architecture's breadth, flexible motivations using feelings, explicit attention mechanism, and continual, incremental and online learning in several modalities provide a significant first step in the direction of the BICA challenge. We also measure LIDA against the architectural features listed in the BICA Table of Implemented Cognitive Architectures. Applying recent brain connectivity results, we go on to elucidate the relationship between LIDA and the underlying and motivating neuroscience, using the language of non-linear dynamics. In particular, we claim that LIDA's representations correspond to basins of attraction in the non-linear dynamics of neural activation patterns. In addition, we claim that the rhythms of LIDA's cognitive cycle and of its internal cognitive elements have definite psychophysiological corollaries in the oscillatory patterns observed in the human brain.
