How the Human Brain Evolved to Harness Abstract Thought

In other primate species, the brain areas that comprise the default mode network involve two systems that are not strongly connected to each other. The regions, one responsible for cognitive tasks and the other for the suppression of external events, appear to be only recently linked by evolution. This linkage may have facilitated the capacity for abstract thought that lead to the rapid evolution of human cognitive abilities.

Low-Income Kids Use Different Brain Function to Ace Achievement Tests

Children from lower socioeconomic backgrounds with stronger connectivity between the lateral frontoparietal network and default mode network performed better in educational tests than those with weaker connectivity. The reverse was true for children from more privileged backgrounds.

Dunbar’s Number: Why the Theory That Humans Can Only Maintain 150 Friendships Has Withstood 30 Years of Scrutiny

Thirty years ago, Robin Dunbar theorized humans can maintain a friendship group of 150 people, with five intimate friendships. Despite many attempts to challenge the theory, Dunbar's Number has stood the test of time. Backed by neuroscience and statistics, Robin Dunbar explains why his theory still prevails.

What Happens in the Brain When We Imagine the Future?

When we imagine the outcome of future events, two sub-networks of the brain become active. One of the sub-networks focuses on creating the new event in our imagination, the other evaluates whether the event is positive or negative.

Are There Differences in the Brains of Autistic Men and Women?

In both neurotypical males and people on the autism spectrum, researchers found a reduction in resting-state brain function in the default mode network. Additionally, connectivity between the two hemispheres in the visual cortex is reduced in women with ASD.
