Stegosaurus is one of those dinosaurs we all recognise straight away—big, slow, covered in plates, and dragging a spiky tail ...

Think dolphins have the largest brain-to-body ratio? Think again! Scientists have identified a surprising U.S. animal that has an even more impressive brain-to-body proportion, giving it a unique ...

Rather than overpowering our animal brain, we should be embracing it. At a time when we’re more stressed out and overwhelmed than ever, tuning into our animal instincts could be the key to ...

As an animal gets larger, its brain size increases as well, though not in direct proportion – it is not a one-to-one relationship. This phenomenon is called allometric scaling .

It traces each and every one of the 139,255 neurons in the brain of Drosophila melanogaster, along with the 50 million connections between them, and is by far the largest and most detailed ever ...

Scientists discovered that the brain keeps making new neurons even in adulthood, offering hope for brain health treatments.

A new modeling study helps confirm that key connections in the brain are formed in the same way across different animal species, likely including humans. When you purchase through links on our ...

Unlike other primates, humans are exposed to high levels of placental sex hormones in the womb, which may have shaped our ...

The largest animals do not have proportionally bigger brains - with humans bucking this trend - a new study published in Nature Ecology and Evolution has revealed. Researchers at the University of ...

The first intelligence transition was the development of animals with a nervous system. Some have argued single-celled organisms show adaptive and complex behavior and forms of learning, but these are ...
