Longitudinal research by Giedd
4 important questions on Longitudinal research by Giedd
What were some of the key findings from Giedd's study on brain development?
- Male brain is 12 percent bigger than female brain
- Total gray matter decreases while white matter increases
- Gray matter in each lobe shows an inverted U-shape, with pruning after a peak
- Gray matter loss occurs earliest in primary sensorimotor areas and latest in dorsolateral prefrontal cortex
What distinguishes Giedd's study on brain development from cross-sectional research?
- Involves longitudinal data
- Age ranges from 6–23 years
What are some notable observations regarding gray matter development in Giedd's study?
- There is an increase followed by a decrease in gray matter, reflecting changes in size and complexity
- Gray matter loss occurs earliest in primary sensorimotor areas and latest in the dorsolateral prefrontal cortex
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Describe the changes in brain volume over time based on Giedd's study findings.
- Male brain is 12 percent bigger than female brain, even when considering height and weight
- White matter increases linearly from age 6 into the early 20s
