Sometimes it’s hard to understand why scientists do what they do. Why spend a career studying cells, fungus, or flies? Other than being nerdy and wanting to learn about our world, what’s the point?Continue reading
From that evil itch on your arm to torturous diseases such as malaria, Zika, dengue, and yellow fever, mosquito bites can have unpleasant consequences. But have you ever wondered why those skin-diving insects are so good at detecting humans? Not so surprisingly, the answer lies in neuroscience — in a special field called chemosensation, the sensing of chemical stimuli.Continue reading
The octopus almost reaches alien status when it comes to its brain and nervous system. And yet, the differences can help us understand more about the human brain as well as unique solutions nature has come up with for difficult problems like camouflage. Octopuses can see polarized light, but cannot see color. However, their skin changes both color and texture to camouflage with the surroundings.Continue reading
What does eye-witness identification have to do with neuroscience? A lot, actually.Continue reading
Everyone knows sharks are fierce predators. How exactly they hunt so well is in part due to their extra sixth sense: electroreception!Continue reading
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.
Why do they go untreated?
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
“If the doors of perception were cleansed every thing would appear to man as it is, Infinite.” – William Blake
The friendly headlamps and grill of a car. A sly electrical outlet. The full moon gazing back at you. A strangely anthropomorphic cloud. A house with personality.Continue reading
What would the world be like without color? Imagine you are a neurophysiologist, who studies color perception. You know that light is a wave and that humans perceive color according to differential activation of color receptors, known as cones, in the retina. You know that red cones are sensitive to long wavelengths, green cones are sensitive to medium wavelengths, and blue cones are sensitive to short wavelengths. There’s just one issue: your entire life, you have been confined to a dark room where your only access to the outside world is a black and white television monitor. You have never seen color.Continue reading
