Our sense of sight is arguably our most important sense. Imagine how different your life would be if soon after birth, you lost the ability to see. For over 1.4 million children worldwide, that is their life. Being blind in developing countries like India has a costly impact: over 90% of blind children do not go to school, less than 50% make it to adulthood, and for those that do, only 20% are employed. But the real tragedy is that many of these cases of childhood blindness are completely avoidable and even treatable.
Have you ever wondered if you experience the world like everyone else? We assume that our senses tell us what’s going on in the world, but they’re far from perfect. Synesthesia is a cool example of when our senses have a mind of their own.Continue reading
Our eyes contain millions of color-sensitive cells, called cones, which maximally respond to red, green, and blue light. With just these three types of color receptors, we can see the full rainbow of our world.Continue reading
When we see the world, there is a huge amount of processing that occurs in the neural circuits of the retina, thalamus, and cortex before we can even begin to comprehend our environment. And all of this computation happens very quickly! In this interview with Dr. Botond Roska, Senior Group Leader at the Friedrich Miescher Institute for Biomedical Research in Basel, Switzerland, we discuss his research on the elements of the visual system that compute visual information as well as how this knowledge can be used to help blind patients. Dr. Roska was inspired by the work and scientific approach of David Hubel (more about this on Wednesday!), and continues to follow his example: “Listen to the experiment, and not your colleagues,” says Dr. Roska. But what would he be, if not a neuroscientist? Find out in my conversation with Dr. Roska, who also shares his story of transition from musician, to medicine, to mathematics and to neuroscience!Continue reading
