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 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!
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
You’re on your way to the traditional Thanksgiving family get-together. You drive down a familiar street, locate your familiar house, and park in a familiar spot.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
I would like to express my upmost gratitude for the vast amount of receptors you possess. Among my favorites – the practical ones that allow me to find keys at the bottom of my large jet-black bag, the emergency ones that warn me the fajita plate is searing, and those truly special ones that enable me to feel my lover’s caress and help me achieve orgasm…Continue reading
Our eyes contain millions of color-sensitive cells, called cones, which maximally respond to red, green, and blue light. With just these three types of color receptors, we can see the full rainbow of our world.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
