Are bigger brains better?

Neuroscience NewsJanuary 16, 2020

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...

All Too Human: The Price We Pay for Our Advanced Brains May Be a Greater Tendency to Disorders

Neuroscience NewsJanuary 22, 2019

Researchers report the neural code of the prefrontal cortex is more efficient than the amygdala in both humans and primates. The lower resistance of the amygdala to errors in humans may play a role in exaggerated survival responses, such as those seen in anxiety and PTSD.... Read More...

Bigger Brains Could Increase Cancer Risk

Neuroscience NewsOctober 29, 2018

A new study reports bigger brain size could mean an increased risk of developing brain cancer. The reason, researchers say, is simple. Bigger brains have more brain cells, and thus a greater potential for cell mutations that lead to cancer.... Read More...

Small Brained Female Guppies Are Not Drawn to Attractive Males

Neuroscience NewsOctober 8, 2018

A new study reports female guppies with smaller brain mass can distinguish between attractive males, but do not find them more appealing or choose to mate with them over less attractive guppies. Researchers say the study sheds new light of the link between mate preference and cognitive ability.... Read More...
