Normal, physiologic, autoregulated blood flow to the brain is central to essentially all aspects of human health, and when it goes wrong, the results can be catastrophic. However, due to our thick skulls and the array of vascularized tissues in the head, monitoring blood flow in the brain proves challenging and can sometimes require time-consuming procedures in situations where time is not in abundance. To provide a solution to this problem, a multidisciplinary team of researchers (left) has developed a device dependent on speckle contrast optical spectroscopy to plug this gap. Here, we speak to Charles Liu – Director of the...
