We have discovered an unexpected correlation between the operational temperature of the brain and cognitive abilities across a wide variety of animal species. This correlation is extracted from available data in the literature of the temperature range ΔT at which an animal’s brain can operate and its encephalization quotient EQ, which can be used as a proxy for cognitive ability. In particular, we found a power-law dependence between ΔT and EQ. These data support the theory that the brain behaves as a critical system where temperature is one of the critical parameters, tuning the performance of the neural network.

大脑中的关键性：神经形态计算的证据和意义

我们发现大脑的操作温度与多种动物物种的认知能力之间存在出乎意料的关联。这种相关性是从文献中动物大脑可以工作的温度范围ΔT及其脑电商EQ的可用数据中提取的，该脑电商EQ可以用作认知能力的代理。特别是，我们发现了ΔT与EQ之间的幂律相关性。这些数据支持理论，即大脑是一个关键系统，其中温度是关键参数之一，可调节神经网络的性能。
