A rat had basically no brain, but it could still see, hear, smell, and feel
Rat R222 was born with hydrocephalus. Neuroimaging revealed most of its brain had compressed and collapsed as it filled with fluid. However, despite its condition, the animal was still able to see, hear, smell, and feel like other animals. The study sheds new light on neuroplasticity, and the findings could have implications for the development of new machine learning technologies.... Read More...
Hot flashes impair memory performance
Vasomotor symptoms, including hot flashes in postmenopausal women, may contribute to memory performance problems. Neuroimaging reveals hot flashes caused alterations in brain function during memory encoding and retrieval tasks, specifically within the hippocampus and prefrontal cortex.... Read More...
A new role for neurogenesis
Dentate gyrus neurogenesis acts to replace lost neurons and restore function following massive neuron loss. ... Read More...
Are bigger brains better?
Greater hippocampal volume is not always a reliable predictor of learning and memory ability in older adults. Faster learning was only found in older adults who had both greater hippocampal volume and more uniform white matter connections to other parts of the brain.... Read More...
