Also known as the cock-eyed squid, this beautiful and weird creature is unique not only because of its similarities to a strawberry, but also because of its two very special eyes. Like many others creatures who live in the deep ocean, the strawberry squid has figured out a special way to spy on prey in little to no light. Learn more in the infographic below:
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
Our brains are split into two halves, a left hemisphere and a right hemisphere. While the left brain specializes in languages, the right brain specializes in faces. But the two halves don’t exist as two separate entities. Instead, both halves or hemispheres are connected at several points. These connections are important to transfer and coordinate information between hemispheres. But how do the correct neurons “know” if and where they should cross? The textbook model so far has described a positive chemical signal called Netrin that diffuses in the developing brain and guides crossing neurons. But new approaches to this question recently suggested a very different answer.
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!
Cognitive scientists have known for decades that humans are inherently irrational when it comes to making economic decisions. This may seem obvious to a good poker player, who will likely utilize mathematical probability to make economic decisions during a poker game, but to most people the fact that they have systematic economic biases might come as a surprise.Continue reading
What is the brain? Researchers conceive of neurons as information processing units, meaning that the circuits formed by neurons support logical and mathematical operations. In this view, the brain is a computer. But it was not always so.Continue reading
Nature is so predictable. Or is it? On Monday, August 21, 2017, thousands will travel to see the first total solar eclipse in the contiguous United States since 1979. Peering back into the minds of our ancestors, we often recount ancient eclipse memories as omens of chaos.Continue reading
Fly lips are called labellum and fly feet are called tarsi. Both the labellum and tarsi contain taste receptors which help the fly find food. Think about that the next time a fly lands on your donut!
“The mind loves the unknown. It loves images whose meaning is unknown, since the meaning of the mind itself is unknown.” – René Magritte
Magritte’s comments on our fascination with the unknown rings true not just in artistic surrealism, but also in many of our scientific research endeavors. The human mind is continually fascinated with what it has yet to understand, and curiously enough, the human mind itself is one such mystery. However, recent efforts focused on imaging and analyzing the entire brain, performed by both scientists and artists alike, have helped shed some light on this mystery. With this new technology, however, comes the question of how neuroimaging can influence the perspectives of a sentient being. What does it mean to see a reflection of our own cognition, both for our understanding of science and for our perception of humanity and living creatures?
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?
Brittle stars are covered in protective outer plates, but they also have another structure of internal plates. A particular species of brittle star seems to be able to use these internal plates for vision: it reacts to visual stimuli, like the presence of a predator or a safe place to hide.
The phrase, “beauty is in the eye of the beholder” seems especially true for scientists. What we study becomes not only intellectually beautiful, but also literally beautiful: the form is pleasing to the eyes. Appreciation and endearment develops over time as scientists gaze on their subject for hours, days, years. In fact, research by the psychologist Robert Zajonc shows that the more familiar you are with something, the more likely you are to enjoy it.
