Which fibers are responsible for conducting impulses within the same hemisphere?

Association fibers are responsible for conducting impulses within the same hemisphere of the brain. These fibers connect different cortical areas within a single hemisphere, facilitating communication between regions that perform different functions. For instance, they play a crucial role in integrating sensory information and coordinating complex motor tasks by linking areas that process visual, auditory, and other sensory inputs with areas responsible for planning and executing movements.

In contrast, commissural fibers connect corresponding areas of the left and right hemispheres, enabling communication between the two sides of the brain. Projection fibers extend from the cerebral cortex to lower brain regions and the spinal cord, allowing for the transmission of information between the brain and the rest of the nervous system. Sulci fibers is not a recognized classification of white matter tracts within the brain. Understanding the role of each type of fiber helps clarify how information is processed and coordinated in the brain's complex network.
