A study in Psychiatry Research: Neuroimaging found structural differences in the precuneus, a brain region associated with memory and self-focus, in individuals who tend to ruminate, which is common in depression.

A study found that by age three, children can understand the intentions behind others' actions through the mirror neuron system. This system allows them to mimic and anticipate actions, which is crucial for social development.
Researchers have mapped the complete neural connectome of a fruit fly, detailing all 139,255 nerve cells and their connections. This advance offers insights into how the brain processes information.
