Optical imaging relies on shining weak lasers through the skull to visualize brain activity. These techniques are inexpensive and relatively portable. They are also silent and safe: Because only extremely weak lasers are used, these methods can be used to study everyone, even infants.

PET is one of the most important techniques for measuring blood flow or energy consumption in the brain. This method of measuring brain function is based on the detection of radioactivity emitted when positrons, positively charged particles, undergo radioactive decay in the brain.

Providing a high-quality, three-dimensional image of organs and structures inside the body without X-rays or other radiation, MRIs are noninvasive and unsurpassed in the anatomical detail they show.

Medical professionals have come to rely on even more specialized forms of the MRI machine, each suited to spotting specific warning signs.

The moment light meets the retina, the process of sight begins. About 60 years ago, scientists discovered that each vision cell’s receptive field is activated when light hits a tiny region in the center of the field and inhibited when light hits the area surrounding the center.
