How the brain 'approximates' without actually counting

From the time of early infancy, humans are endowed with the capacity to approximate the number of objects in their visual field, an ability that continues throughout life and may underlie the development of more complex mathematical ...

A new window into macaque brain connections

Researchers can now see how the two sides of the living brain mirror each other thanks to a new combination-imaging technique. The method dubbed "opto-OISI" takes advantage of rapidly developing high-resolution optical technologies ...
