The larger of the two triangular geometric features (scale bar = 10 cm.). Credit: Charles Helm The Pleistocene epoch, which started 2.6 million years ago and lasted until about 11,700 years ago, was ...

Scientists have identified grid cells, neurons that fire in repeating triangular patterns as the eyes explore visual scenes, in the brains of rhesus monkeys. This is the first time grid cells have ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

The Pleistocene epoch , which started 2.6 million years ago and lasted until about 11,700 years ago, was crucially important for our hominin ancestors. Homo sapiens first evolved in this era, about ...
