A Stanford-led study suggests that some children who struggle in math may have trouble adjusting their approach after errors during number-comparison tasks, rather than having only a core difficulty with numbers. Using brain imaging and computational modeling, researchers reported weaker activity in brain regions involved in monitoring performance and adapting behavior, patterns that also helped predict which children were more likely to struggle.
Researchers at the Institute of Science and Technology Austria have found that the brain's memory center, the hippocampus, begins life with a dense, seemingly random network of connections rather than a blank slate. This network refines itself through pruning, becoming more organized and efficient over time. The discovery challenges the traditional tabula rasa concept.

A common belief that the frontal lobe fully develops by age 25 has been challenged by recent neuroscience findings. New brain-imaging studies reveal that key neural wiring and network efficiency evolve well into the early 30s. This extended timeline highlights ongoing maturation processes in the brain.
A peer‑reviewed study of New York City children reports that higher prenatal exposure to the insecticide chlorpyrifos is associated with widespread differences in brain structure, function, and metabolism—and with poorer motor skills—that persist into adolescence.

Researchers in Italy have found that a ketogenic diet can shield young rats from the long-term mental and behavioral impacts of prenatal stress. The high-fat, low-carbohydrate regimen, administered after weaning, improved sociability and reduced stress-related issues in the offspring of stressed mothers. These findings, presented at the ECNP conference in Amsterdam, suggest potential early dietary interventions, though human trials are needed.
