2. Cells of cortex of posterior part of frontal lobe give fibres to form frontal pontile 

 path through frontal parts of corona radiata ,:nd internal capsule and through 

 medial part of cerebral peduncle to nuclei of pons.

3. Cells of cortex of temporal lobe (two upper gyri) give fibres to form temporal pontile 

 path which passes under the lenticular nucleus into lower part of occipital portion 

 of internal capsule and outer part of cerebral peduncle to nuclei of pons.
