Brains Are Not Required When It Comes to Thinking and Solving Problems–Simple Cells Can Do It
The planarian is nobody's idea of a genius. A flatworm shaped like a comma, it can be found wriggling through the muck of lakes and ponds worldwide. Its pin-size head has a microscopic structure that passes for a brain. Its two eyespots are set close together in a way that makes it look cartoonishly confused.
The most detailed map ever of the brain’s memory hub
The hippocampus supports multiple cognitive functions, including episodic memory. It does so in coordination with other brain regions. Australian scientists have created the most detailed map ever made of the communication links between the hippocampus and the rest of the brain. This map may change how we think about human memory. Scientists generated this map
Brains of Cosmonauts “Rewired” During Space Missions
A new study published in Frontiers in Neural Circuits is the first to analyze the structural connectivity changes that happen in the brain after long-duration spaceflight. The results show significant microstructural changes in several white matter tracts such as the sensorimotor tracts. The study can form a basis for future research into the full scope…
Cosmonaut brains are ‘rewired’ by space missions, scientists find
Home News Science & Astronomy In a new study, researchers have shown how spaceflight affects the brains of cosmonauts. (Image credit: Ivar Mendez) Our brains change as we age and grow here on Earth. But what happens to the human brain after being in space for a long time?In a new study, a collaborative effort…
The brain’s secret to lifelong learning can now come as hardware for AI
When the human brain learns something new, it adapts. But when artificial intelligence learns something new, it tends to forget information it already learned. As companies use more and more data to improve how AI recognizes images, learns languages and carries out other complex tasks, a paper published in Science this week shows a way…
Cat brains are shrinking, and it’s all humans’ fault
Home News A house cat and its puny, puny brain. (Image credit: Getty Images) Thousands of years of human dependence has shrunk your cat's brain, new research suggests.In a study published Jan. 26 in the journal Royal Society Open Science, researchers compared the cranial measurements (an indicator of brain size) of modern house cats with…
Objects appear to be stable despite constant changes in their retinal images. This happens due to many sources of internal and external noise. How does our visual system achieve this apparent stability? New research by the UC Berkeley scientists reveals that our brains are constantly uploading rich, visual stimuli. We see earlier versions instead of…
