The platypus and the echidna are the only mammals that have the power of electroreception, which means they can sense electrical changes. Check out this new Weird Animal Brain to learn how the platypus uses its bill to catch prey underwater!
Epigenetics change which genes are active and which are inactive. Research over the past few years has shown that these changes are important for protecting the brain from neurodegeneration and injury. A review paper came out on May 18th in the journal Nature Reviews Neuroscience that summarizes this research. Check out the infographic for a description of the review paper.
The brain is one of the most complex and amazing structures in the universe. It allows us to experience the world, feel, remember, and plan for the future. But for at least one organism, the brain is only a means to an end. Learn more in the infographic below!
It’s easy to find information on the internet — especially information that confirms what you already believe to be true. Through search engine bias, your Facebook newsfeed bubble, and confirmation bias, we can unknowingly surround ourselves with a cozy blanket of comforting information. Whether or not this information is true, however, is a different story. Check out this infographic for some strategies for how to know if what you’re reading is true.Continue reading
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
