Magnetoencephalography (MEG) is a tool used to assess brain activity. It works by measuring the magneticfields present within the human brain, these fields are causally altered by electrical currents in the brain. Thesecurrents originate from flow within the neurons, the core cell present within the brain. There are at present alarge user base of researchers and clinicians that utilize MEG to assess theories of action perception, to thediagnosis of concussion. The current technology uses a sensor type called a SQUID, which requires a cryogenvessel. In this project we wish to explore other types of sensor technology that do not require SQUIDs.

脑磁图(MEG)是一种用于评估大脑活动的工具。它的工作原理是测量人脑中存在的磁场，这些磁场会因大脑中的电流而发生变化。这些电流来自神经元内部的流动，神经元是大脑中存在的核心细胞。目前有大量的研究人员和临床医生利用脑磁图来评估动作知觉理论，用于脑震荡的诊断。目前的技术使用一种名为鱿鱼的传感器类型，它需要一个低温容器。在这个项目中，我们希望探索不需要SQUID的其他类型的传感器技术。
