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 neocortex stands out as a stunning achievement of biological evolution. All mammals have this swath of tissue covering their brain, and the six layers of densely packed neurons within it handle ...

This ‘NOVA’ presentation delves into the development of brains—those of both humans and some of our intelligent fellow ...

What makes us human? According to neurobiologists it is our neocortex. This outer layer of the brain is rich in neurons and lets us do abstract thinking, create art, and speak complex languages. An ...

A new study is providing fascinating insight into how projections conveying sensory information in the brain are guided to their appropriate targets in different species. The research, published by ...

The neocortex of our brain is the seat of our intellect. New data suggests that mammals created it with new types of cells that they developed only after their evolutionary split from reptiles. The ...
