This project asks how the statistical mechanics of critical processes such as avalanches underpin mammalian cognition. This is important because self-organising criticality has been proposed as a general explanation of the architecture and operating point of brain circuitry, however until now it has not been possible to relate it to cognitive function itself. We bring an inter-disciplinary approach to bear upon this problem, simulating neuronal mechanisms at scales from sub-cellular to brain-wide, and employing a new mesoscopic neuroimaging technology to detect avalanches and measure distance to criticality in very large (~10,000) populations of neurons during a cognitive task. This will bring new insight into system-wide brain function during health and disease states.

该项目询问关键过程的统计力学，例如雪崩等哺乳动物认知的基础。这很重要，因为已经提出了自我组织的临界性作为对脑电路的结构和操作点的一般解释，但是到目前为止，不可能将其与认知功能本身联系起来。我们为这个问题带来了一种跨学科的方法，模拟了从细胞细胞到大脑的尺度上的神经元机制，并采用一种新的介质神经影像学技术来检测雪崩并测量非常大的（〜10,000）在认知任务中的神经元种群中的距离（约10,000个）。这将为健康和疾病状态期间对系统范围的大脑功能带来新的见解。
