The Visual World & The Brain

Research Overview

The brain is a fascinating structure that has evolved over 500+ million years to explore and interact with the environment. Brains capture information through the senses and, in humans, vision dominates sensory perception. To comprehend what we see, our brain parses each image into basic building blocks just as it parses sentences into words and letters to comprehend text. The Alonso laboratory investigates the brain circuits involved in this image parsing process, and their role in visual disorders such as myopia, amblyopia and glaucoma. The laboratory has made major contributions towards understanding the organization and function of two main brain pathways involved in processing light and dark stimuli. These two pathways, called ON and OFF because they respond to light-on or light-off, play a crucial role in vision. They originate in the eye at the very first synapse of the visual system and are present in all species that can form images, from flies to humans.

The Alonso laboratory demonstrated that ON and OFF pathways remain functionally segregated throughout the visual system, but can also converge in the same brain cell and work together. The functional segregation explains why humans do not become blind when genetic mutations inactivate ON pathways. The convergence (ON-OFF edge detectors) explain why humans only require a few lines to accurately identify stimuli such as face sketches. The Alonso laboratory also demonstrated that ON and OFF pathways have different stimulus preferences, with ON pathways responding better to bright stimuli, large surfaces, low contrasts, and slow motion. These preferences are ideal to extract information from a bright visual world that is slowly drifting with self-motion, but also make ON pathways vulnerable to stationary vision in poorly-illuminated environments. Recent work from the Alonso laboratory also indicates that poor stimulation of ON pathways increases the risk of developing myopia (nearsightedness), a visual disorder that blurs vision at far distance and is becoming a global epidemic.
