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
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 be prevented and treated? These are the questions that get Professor Lynne Kiorpes up in the morning! Listen to her passion as she explains her research and life as a neuroscientist: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?
What brain regions are employed when we interact with other people? Cognitive neuroscientist Sarah-Jayne Blakemore explains the “social brain” in her TED talk and sheds light on the complex networks that enable us to evaluate the mental states of other people. Her research focuses on the development of the social brain during adolescence. Watch Dr. Blakemore’s TED talk for more information on how the brain matures during the transition from adolescence to adulthood.Continue reading
“I would there were no age between sixteen and three-and-twenty, or that youth would sleep out the rest; for there is nothing in the between but getting wenches with child, wronging the ancientry, stealing, fighting…”
The old shepherd’s thoughts from Shakespeare’s A Winter’s Tale resonate centuries later when we consider examples of stereotypical teenage behavior – emotional outbursts, angst, and recklessness just to name a few. But if we dismiss teenagers as lacking emotional discipline, we fail to understand the complex neural underpinnings that drive much of this behavior and allow a concerned adult to guide teens through this critical stage of brain development.Continue reading
The human brain continues to develop and form new connections from birth until as late as the mid-20s. During this time, billions of connections are made and broken as the brain develops the architecture required for learning, memory, language, emotion and many other brain functions. Disruptions in how the brain forms connections during infancy and early childhood can severely impair growth and negatively affect brain functions. Continue reading
The sense of hearing is a critical part of how we experience life and the world around us. It is so important, in fact, that the ears are fully formed and functional when we are born. Despite its significance, hearing is often underappreciated until it is lost. Hearing loss affects more than 10% of all people worldwide. Whether it is due to age, exposure to loud noises, or genetic mutations, hearing loss occurs when hair cells, the receptors in the ears that respond to sound, become damaged and die. One of the biggest challenges in counteracting hearing loss is that hair cells cannot repair or regenerate themselves, so the damage is often permanent.Continue reading
Every once in a while, we hear of amazing scientific feats about how some new drug successfully reduces weight without dieting or exercise in monkeys, or how scientists slowed aging in worms and doubled their lifespans. These studies are often a cause for ridicule in the media, which reduces their significance and validity by implying that mice, flies, birds—any animal really—is not a true representation of the human condition.Continue reading
