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
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 . However, their skin
When babies are born, they cannot see very well, but their vision vastly improves as they continue to develop. Sometimes, the eyes don’t communicate well with the brain, and vision disorders like amblyopia result. What are the neural mechanisms that allow normal visual development? What happens when things go amiss? And how can these disorders
What does eye-witness identification have to do with neuroscience? A lot, actually. Tom Albright is Professor and Director of the Vision Center Laboratory at the Salk Institute for Biological Studies in La Jolla, CA. His research focuses on understanding how the brain interprets visual information so that we can thrive in our visually stimulating world.
Everyone knows sharks are fierce predators. How exactly they hunt so well is in part due to their extra sixth sense: electroreception! Exactly how sensitive are the ampullae of Lorenzini? By measuring brain activity, scientists can test how large electrical changes have to be for a shark to notice. They found that sharks can sense
It is no surprise that a child prefers its mother’s voice to those of strangers. Beginning in the womb, a fetus’s developing auditory pathways sense the sounds and vibrations of its mother. Soon after birth, a child can identify its mother’s voice and will work to hear her voice better over unfamiliar female voices. A
My father often jokes that hundreds of years from now, future anthropologists will speak of the cult of the Seattle goddess, her shrine adorning every airport, shopping mall, and train station in America. The worshippers partake in a holy communion of coffee, tea, and espresso. In fact, anthropologists today tell us that in some indigenous
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
The minds of individuals are like parallel universes, forever inaccessible to one another. Never do we truly see through the eyes of another person. It is common for us to wonder if other people experience the world in the same way we do. Is your green my red? Is my yellow your blue? While we
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.
We have someone new joining our team! She is a neuroscience PhD student at the University of Iowa, and she studies speech perception – but let’s let the animation she created explain exactly what that means: Among neuroscientists, there is a huge range of topics to study and methods with which to study them. This is
