The nurse notes that a patient with damage to the diencephalon region of the cerebrum is demonstrating a breathing pattern where regular periods of deep rapid breathing are followed by periods of apnea. The commissural fibers or transverse fibers are axons that connect the two hemispheres of the brain.
The posterior commissure and the habenular commissure are small fiber bundles traversing the midline that connect caudal parts of the diencephalon Figs. Brain-18 Cerebrum Cerebral Medulla nerve tracts connect the cortex to other areas of cortex or other parts of the CNS Association fibers connect areas of cerebral cortex within the same hemisphere Commissural fibers connect the cerebral hemispheres Corpus Callosum Projection fibers between the cerebrum and other parts of the brain and spinal cord Internal. Damage to the causes major disruptions in endocrine system functions as it controls hormone secretions from the pituitary gland.
Motor tracts from the cerebrum and sensory tracts to the cerebrum are examples. Commissural fibers connect an area in one hemisphere with an area in the opposite hemisphere. The whole lateral wall of the rostral and caudal diencephalon is traversed by numerous transverse longitudinal and commissural fibers that interconnect the diverse prosomeric centers into interactive circuitry Figs.
Commissural fibers connect the cerebrum to the diencephalon. In human neuroanatomy axons within the brain can be categorized on the basis of their course and connections as association fibers projection fibers and commissural fibers.
