Serotonin can act as a growth factor for the stem cells in the fetal human brain that determine brain size. During human evolution, the size of the brain increased, especially in a particular part ...

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 ...

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 ...

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 ...

In a bid to better understand, and potentially treat, a host of conditions that affect early cognition, neurodevelopment and the brain later in life, investigators at Johns Hopkins Medicine and ...

A human-specific gene causes a larger neocortex in the common marmoset, a non-human primate. A human-specific gene causes a larger neocortex in the common marmoset, a non-human primate. The expansion ...
