Researchers report the thalamus plays a critical role in regulating how the brain learns to integrate binocular input during development.
During childhood, the brain goes through critical periods in which its learning ability for specific skills and functions is strongly increased. It is assumed that the beginning and ending of these critical periods are regulated in the cortex, the outermost layer of the brain. However, scientists from the Netherlands Institute for Neuroscience discovered that a structure deep in the brain also plays a crucial role in the regulation of these critical periods. These findings, published today in the leading journal Nature Neuroscience, have important implications for understanding developmental problems ranging from a lazy eye to intellectual disability.
