The Brodmann Areas delineate parts of the brain that perform certain sensory tasks. Korbinian Brodmann devised his map of the brain in 1909 based solely on the organization of the cells in different regions. Since then many of the areas he defined have been correlated with diverse cortical functions for instance movement sight hearing touch and language. In the first year of life neural connections in the brain are being made especially rapidly. By the end of the first year the infant brain resembles that of an adult more than that of a newborn. Because babies' brains are so receptive and mature very quickly in the first year appropriate stimulation is particularly important.
