Because PNI was defined as cancer cells infiltrated into the perineurium or neural fasciculus intramurally, it could be classified into 2 subgroups: extramural PNI group (cancer cells infiltrated only into the perineurium; the neural fasciculus was intact) and intramural PNI group (cancer cells penetrated perineurium and neural fasciculus was invaded).

They found that the arcuate fasciculus, a collection of nerve fibres connecting auditory regions at the temporal lobe with the motor area located at the frontal lobe in the left hemisphere of the brain, allows the 'sound' of a word to be connected to the regions responsible for its articulation.
