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
Every March, Brain Awareness Week (BAW, for short) unifies the world in celebration of the brain and mind! In order to raise awareness about how the brain works, what neuroscientists do, and how amazing new research is, scientists present interactive activities, host laboratory tours, and speak to audiences about brain-related topics.
This year, we put together a list of our favorite Knowing Neurons content that highlight how amazing the brain is! Check them out and share the awesomeness!Continue reading
What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter. Particle accelerators allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions. By delving into the mysteries of the Universe, colliders have entered the Zeitgeist and tapped the wonders and fears of our age.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
Would you trust a memory if it felt as real as all your others? And other people confirmed they remember it, too? What if the memory turned out to be false?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
Brain stimulation might sound like some Frankensteinian demonstration from a Victorian science fair. But in reality, it is a contemporary technique making a huge impact in neuroscience by addressing a longstanding limitation of traditional methods for investigating human brain function. Such techniques, like EEG and fMRI, can only be used to infer the effects of a stimulus or task on brain activity, and not vice versa. For example, a scientist might use EEG to study the effect of a task like arm movement on brain activity, but how can one study the effect of brain activity on arm movement?Continue reading
Knowing Neurons had an amazing year, and we are so thankful for all your support throughout our journey! Here are some highlights from 2016!Continue reading
Last month, on the big island of Hawaii, I swam with giant, beautiful aliens. Or at least that’s what it felt like. I went night snorkeling with manta rays and had the privilege of seeing 10 or 11 graceful behemoths. Some had a wingspan of over 10 feet long. Before our group got in the water, to prepare us for what we were about to see, our guide reassured us that manta rays are like sharks, but only the good parts, none of the scary parts. They don’t have teeth, they only eat plankton, and they have no stinger like their sting ray counterparts.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
Cute things are usually vulnerable, fragile and weak. But cuteness itself is mighty indeed. Morten L. Kringelbach and his colleagues at the University of Oxford recently described cuteness as ‘one of the most basic and powerful forces shaping our behavior.’ And yet, despite its elemental importance, cuteness might be a fluid, evolving concept and trait.Continue reading
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 2014 study of preterm infants showed that playing a recording of the mother’s voice when babies sucked on a pacifier was enough to improve development of oral feeding skills and shorten their hospital stay. A mother’s voice can soothe a child in stressful situations, reducing levels of cortisol, the stress hormone, and increasing levels of oxytocin, the social bonding hormone. Scientists have even traced the power of a mother’s voice to infants’ brains: a mother’s voice activates the anterior prefrontal cortex and the left posterior temporal region more strongly than an unfamiliar voice, priming the infant for the specialized task of speech processing.
While it makes intuitive sense that a mother’s voice has special power over infants and toddlers, what happens as children grow up? Continue reading
