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
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.
Researchers have suspected for a few years that neurotransmitters like dopamine play a role in how the immune system functions. But they didn’t know how cells in the immune system would actually used dopamine. A paper published on July 12 of this year shows for the first time that cells in the immune system send dopamine to other cells to trigger them into action. This is just like how neurons use dopamine in the brain! Check out the infographic for a summary of the discovery!
The Matrix made all of us ask the same disturbing questions: How do I know that the world I see, hear, and touch is real? Can I prove that I’m not actually in a pod created by machines bent on harvesting my bioelectricity?Continue reading
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!
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!
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
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
