The term "recent" in science is a kind of moving target, since new things are happening every day. But one technology that has developed in the past few years is the fMRI. The "f" stands for "functional." This relatively new kind of MRI is able to detect oxygen uptake in the brain, thus allowing great imaging of the brain's activity in real time. This allows us to better see what the brain is doing as we are presented with different stimuli while the fMRI is occurring. The possibilities for insight into how our brains really work are endless. There are researchers looking into what a brain does when making connections among words, and researchers looking into whether this technology can function as a lie detector. In some ways, the brain is the least understood organ in the body, and this powerful new technology will provide us with great information.
