On January 26, I had the honor of visiting the European Organization for Nuclear Research (CERN), one of the largest and most complex scientific research facilities in the world. What was a neuroscientist like myself doing at a particle collider built for physics experiments? Continue reading
The pursuit of science is challenging. It is where new knowledge is born. In their path towards the unknown, scientists, too, face their fair share of insecurity. When experiments fail, grants evade, confidence dwindles and the clock strikes midnight, many researchers find themselves immersed in questions to which Google may not have an answer. What should I do after I graduate? Is there a glass ceiling for women? Is academia right for me? What other options are out there? Can I really get my act together for a work-life balance, like, ever? Sigh, these investment bankers make so much more money. What am I doing with my life? Maybe I should sleep now?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
What does eye-witness identification have to do with neuroscience? A lot, actually.Continue reading
In a recent presidential town hall, President Obama looked directly into the camera and made a powerful statement about mental health. “If something inside you feels like it’s wounded, it’s just like a physical injury. You’ve got to go get help,” said the leader of the free world.
Buried under the weight of a massive social stigma, seeking help or even acknowledging a mental illness can be an excruciating task. How, then, can we help ourselves and our loved ones achieve emotional and mental well-being?Continue reading
It’s a lazy Sunday afternoon. Professor Freeman is enjoying the Southern California weather on Professor Domino’s patio.
Domino: Will it be Coke or Pepsi, Dr. Freeman?
Freeman: That’s an easy choice, Dr. Domino.Continue reading
Ten minutes before I was scheduled to begin my interview with celebrated writer Steve Silberman, I still had not figured out which questions I wanted to ask him. Staring down at a list of over 50 topics, I was overwhelmed by just how much there is to discuss when it comes to the history of the discovery of autism and misconceptions surrounding the diagnosis. Silberman was one of the first members of the mainstream media to bring attention to the rise in autism diagnoses, and I wanted to know why autism had captured his interest. Continue reading
Knowing Neurons is proud to present our inaugural entry in a new series of YouTube videos! In this episode, Joel asks, “Is the brain smarter than a computer?” With Joel as our tour guide, we embark on a journey through neurobiology, psychology, supercomputing, quantum physics, and even philosophy, all the while stopping on the street to ask the common person for thoughts and opinions. Along the way, you’ll learn in what ways humans outperform computers, in what ways computers outperform humans, how the world’s most powerful supercomputers are simulating the human brain, the limits of human memory, how chess grandmasters memorize chess positions, what information in your brain is accessible to your conscious mind, and what it means to live in a simulation.
Buckle your seat belts, sit back, relax, and enjoy the show!Continue reading
If you think about it, the surface of the human body, the skin, is actually one huge sheet of tactile receptors. The dozens of types of receptors that innervate the skin help us connect with our surroundings. But the properties of these neurons – how they are organized in the skin, where the project into the spinal cord and brainstem, and how this organization gives rise to the sense of touch – are actually poorly understood! I spoke with David Ginty, Ph.D., who is Professor of Neurobiology at Harvard Medical School and an investigator with the Howard Hughes Medical Institute, to find out about the newest ways his lab is studying sensory biology.Continue reading
It is easy to assume that if a car has a gas pedal, it needs to have brakes, and similarly, if our brain has excitatory neurons, it needs inhibition too. For a long time, the field of neuroscience had thought of inhibitory interneurons as the “brakes” of the brain, providing suppression to neuronal activity. However, in my conversation with Dr. Gordon J. Fishell, I learned that interneurons are far more fascinating cell types than merely being inhibitory! Their multifarious morphology can be attributed to a palette of functions in brain developmental and regulation.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
