Final answer:
The cerebrum is connected to other brain parts by projection fibers, which include the corpus callosum that facilitates hemispherical communication.
Step-by-step explanation:
The type of neural fibers that connect the cerebrum to other parts of the brain are known as projection fibers. These fibers are responsible for transmitting information between the cerebrum and lower brain regions, such as the brain stem, through the diencephalon, and from those regions into the spinal cord.
The corpus callosum is specifically a structure consisting of projection fibers that connects the two hemispheres of the cerebrum, allowing for communication and the sharing of information between them.
