From bird songs to frog ribbits, animals engage in countless forms of vocalization. However, no other species in the animal kingdom matches humans in complexity of language. The versatility of human speech allows us to discuss anything from what we ate for breakfast to the nature of the universe, and our ability to communicate is essential in all aspects of our lives. Because of this, it is natural for neuroscientists to search for an evolutionary explanation showing us how our unique language capabilities came about. One potential answer to this complicated question lies in the gene FOXP2.Continue reading
Songbirds are one of the few known species who learn to speak (or sing) like we do. That makes them the perfect case study to learn about the origins of language in the brain.Continue reading
A new paper published this month in the journal Cell describes an unexpected finding about memory. Researchers used to think that memory required specific activity from the same brain cells over time. This new result shows something different. Check out the infographic to learn more!
What are you doing right now? I’m no psychic, but I can say for certain one thing that you’re doing: reading. You’re reading this sentence, word by word, and extracting meaning from little black lines of orthography, a fancy term for the rules of written language. If you really think about it, what you’re doing right now is quite difficult. What are the neural processes that enable us to read?
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.
In our previous post, we considered the Philip K. Dick novel Do Androids Dream of Electric Sheep? in the context of a thought experiment: a thinking tool used by scientists and philosophers to reframe an unintuitive problem in a new, more familiar context.
Another great thought experiment of the 1960s is 2001: A Space Odyssey. Developed in parallel as both a novel by Arthur C. Clarke and a film by Stanley Kubrick, Space Odyssey is a story about the evolution of humanity and intelligence. Beginning with the invention of tool use in Africa, the story asks how intelligence might continue to evolve after humans develop sophisticated technology. Both the novel and the film follow astronaut Dave Bowman on his journey to the Outer Solar System guided by HAL 9000, an artificial intelligence (AI) that controls the spaceship and is responsible for the well being of the crew.
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
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
We all know too much sugar is bad for us. But did you know that having unfettered access to sugar might produce brain changes similar to highly stressful situations, such as neglect or abuse? A recent study published in Frontiers in Molecular Neuroscience comparing the effects of unlimited sugar availability and the effects of early life stress in rats might suggest just that.Continue reading
“If the doors of perception were cleansed every thing would appear to man as it is, Infinite.” – William Blake
The friendly headlamps and grill of a car. A sly electrical outlet. The full moon gazing back at you. A strangely anthropomorphic cloud. A house with personality.Continue reading
“Do you know what you did yesterday?” asks the doctor.
“No, I don’t,” responds the patient.Continue reading
