Which came first, overall bigger brains or larger brain regions that control specialized behaviors? Neuroscientists have debated this question for decades, but a new Cornell University study settles the score.
A study recently published in PLOS Biology provides information that substantially changes the prevailing idea about the brain formation process in vertebrates and sheds some light on how it might have evolved.
Epilepsy is a complex neurological disorder that afflicts approximately 50 million people worldwide. Although this disease has been known to exist for centuries, the exact mechanism of its cardinal symptom, the epileptic ...
The first study to investigate how dog brains process speech shows that our best friends in the animal kingdom care about both what we say and how we say it. Dogs, like people, use the left hemisphere to process words, a ...
A change to a more challenging environment could, over time, re-ignite and grow old parts of the brain that have gone inactive, according to a study of army ants led by a Drexel biology professor.
Many bachelor mammals, including lions, mountain gorillas, monkeys, and mice, attack and kill the offspring of other males—a form of infanticide—yet display parental behavior once they themselves become fathers. Now, ...
Researchers from the "Cognitive Neuroimaging" unit at NeuroSpin have identified a network of brain regions whose organisation may at least partly explain the specificity of the cognitive functions of the human species. These ...
An international team of scientists led by Duke University researchers has uncovered key structural differences in the brains of parrots that may explain the birds' unparalleled ability to imitate sounds and human speech.
A fundamental question in neurobiology is how animals, including humans, make decisions. A new study publishing in the open access journal PLOS Biology on October 7 reveals how fruit fly females make a very important decision: ...
Life at opposite ends of primate social hierarchies is linked to specific brain networks, a new Oxford University study has shown.
