How babies integrate new events into their knowledge

Babies seek to understand the world around them and learn many new things every day. Unexpected events — for example when a ball falls through a table — provide researchers with the unique opportunity to understand infants' learning processes. What happens in their brains as they learn and integrate new information?

Reading the past like an open book: Researchers use text to measure 200 years of happiness

Using innovative new methods researchers have built a new index that uses data from books and newspaper to track levels of national happiness from 1820. Their research could help governments to make better decisions about policy priorities.

How neuronal migration and outgrowth shape network architecture

Neurons are not randomly arranged in the human brain. In the cortex, they are organized in interconnected clusters with high intrinsic connectivity. This modular connectivity structure, in which clusters eventually serve as functional units, is formed in early phases of development. The underlying self-organization process is regulated by neuronal activity but the detailed mechanisms are still poorly understood. Based on in vitro studies and computational modeling, neuroscientists have now made an important contribution to the understanding of brain networks and their development: in their current study, they show how neuronal outgrowth and migration interact in shaping network architecture and the degree of modularity in mature networks.

Mild-to-moderate hearing loss in children leads to changes in how brain processes sound

Deafness in early childhood is known to lead to lasting changes in how sounds are processed in the brain, but new research published today shows that even mild-to-moderate levels of hearing loss in young children can lead to similar changes.
