Cerebral Tracts - Shorer

Question 1

What are the three cerebral tracts in the brain?

Answer 1

1. Association:
   connect 2 areas in the same hemisphere
   Short association fibers: from 1 gyrus to a close one
   Long association: stay on one side, but can go farther, like between lobes
   Uncinate fascifulus, superior and inferior longitudinal tracts, cingulum, arcuate fibers
2. Commisural:
   Connect points between 2 hemispheres
   Corpus callosum is the major one (fibers go perpendicular to it)
   Forcepts minor: frontal-frontal
   Forcepts major: occipital-occipital
   Anterior and posterior commissures separate from the corpus collosum. Include interbulbar fibers and intertemporal fibers)
3. Projection
   Vertical connections
   Corticospinal, corticobulbar (brain stem), corticorubrol (frontal lobe to red nucleus) , corticonuclear.
