Counterintuitive? Fish make more brain cells in water rich with carbon dioxide
Fish continuously make new neurons in their brain. Ocean acidification is harmful for marine life, but can it help fish grow even more brain cells? Scientists say – maybe. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the nervous system in water salamanders called axolotls. In my free […]
Why don’t whales have strokes?
Whales can’t breathe underwater. But even though whale brains should be damaged by the lack of oxygen, they aren’t. Scientists have found out why. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the nervous system in water salamanders called axolotls. In my free time, I like to read […]
Sensitive skin? Dolphins feel touch best on their faces
Hands are among the most touch-sensitive body parts for humans, but what about dolphins? Scientists studied how well dolphins feel touch from head to tail – and found the most touch-sensitive parts. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the nervous system in water salamanders called axolotls. […]
Athletic Atlantic salmon grow more brain cells than couch potato Atlantic salmon
Exercise is good for growing muscles – and, as it turns out, cells in the salmon brain. After three weeks of swimming against a strong current, young Atlantic salmon had more cells born in their brains. What does this mean for salmon? Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study […]
No nerves lost: Octopuses can regenerate their nervous system.
Octopuses have complex behaviors, like communicating with other octopuses by changing color patterns of their skin. Damage to the nerve that controls this behavior takes away the skin patterning abilities. As it turns out, this nerve can repair itself after an injury – and colorful patterns come back too. Anastasia YandulskayaI am a PhD candidate […]
Are dolphins losing their minds in blooming ocean waters?
Polluted water is a great source of food for harmful algal blooms, which release even more toxins into the water. And now scientists say that algal blooms may give dolphins Alzheimer’s disease-like brain damage. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the nervous system in water salamanders […]
Bold Fish, Shy Fish: What’s in Their Brains?
Much like people, some fish individuals are adventurous, while others are more cautious. Do differences in the brain function hold the secret to fish personality types? Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the nervous system in water salamanders called axolotls. In my free time, I like […]
