Language Highways
the accurate fasciculus connects the temporal and parietal language areas with frontal areas (also the Broca’s area)
⇒ Broca’s and Wernicke’s Area
During the construction of the cortex, ==each growing excitatory neuron sends out its axon to explore the surrounding regions==, sometimes up to several centimeters away, like a Christopher Columbus of the brain. This exploration is guided and channeled by chemical messages, molecules whose concentrations vary from one region to another and which act as spatial labels. The axon head literally sniffs out this chemical path laid out by our genes, and deduces the direction in which it must go.
