A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning (扫描) what’s happening in their brains.
When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons (神经元) are responsible for this processing.
The fMRI (functional Magnetic Resonance Imaging) (功能性磁振造影) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientist
