Tool-use learning induces BDNF expression in a selective portion of monkey anterior parietal cortex

Learning but not execution of tool-use induced expression of brain-derived neurotrophic
factor (BDNF). The expression was highest in the anterior bank of the intraparietal sulcus,
especially in the region posteriorly adjacent to the somatosensory shoulder and forearm
region in area 3b, suggesting that BDNF plays a role in altering the body image of the hand
to include the repeatedly used tool as its extension.
