The study tests a new type of neuroimaging device designed to easily record brain activity in real time.

The new technology uses existing neuroimaging techniques. The most common form of this technology is called continuous-wave fNIRS, but recently a more detailed and accurate iteration has been developed, called time-domain (TD-fNIRS) fNIRS.

The problem with visualizing the second version of fNIRS is that it often requires large, heavy and expensive machinery. The new device called Kernel Flow has been in development for several years to make TD-fNIRS cheaper in nature, more compact and easier to use.

A study published earlier this year demonstrated Kernal Flow’s ability to provide data on brain activity equal to that recorded by bulky, stationary TD-fNIRS systems. The device is currently being used in a feasibility study to test how effectively Kernal Flow measures the effects of certain substances on the brain.
