In a recent study published in Science, researchers demonstrated how transketolase-like 1 (TKTL1) gene expression influenced neocortical neurogenesis in modern humans. Study: Human TKTL1 implies ...

A single difference in a protein called TKTL1 may have given modern humans a significant advantage over Neanderthals. Scientists have shown that the human TKTL1 variant, but not the archaic variant, ...

Researchers from Dresden uncover a greater neuron production in the frontal lobe during brain development in modern humans than Neandertals, due to the change of a single amino acid in the protein ...

ARHGAP11B -- this complex name is given to a gene that is unique to humans and plays an essential role in the development of the neocortex. The neocortex is the part of the brain to which we owe our ...

The question of what makes modern humans unique has long been a driving force for researchers. Comparisons with our closest relatives, the Neandertals, therefore provide fascinating insights. The ...

The expansion of the human brain during evolution, specifically of the neocortex, is linked to our cognitive abilities such as reasoning and language. A certain gene called ARHGAP11B that is only ...

MAMMALIAN cerebral cortex undergoes rapid structural changes during the postnatal period. Dendritic connexions increase in number and complexity, the volume of neurone somata increases, and ...
