quantitative electron microscopic analysis reveals that approximately 60 million axons connect the two cerebral hemispheres : the corpus callosum contains 56.0 million +/- 3.8 million axons ( n = 8 ) , the anterior commissure contains 3.15 million +/- 0.24 million axons ( n = 8 ) , the hippocampal commissure has 237,000 axons +/- 31,000 ( n = 6 ) , and the basal telencephalic commissure has 193,000 axons +/- 28,000 ( n = 5 ) .
