Textbook Question

Fiber tracts that allow neurons within the same cerebral hemisphere to communicate are:
a. Association fibers
b. Commissures
c. Projection fibers

Verified step by step guidance

Understand the function of fiber tracts in the brain: Fiber tracts are bundles of axons that connect different parts of the brain, allowing communication between neurons. They are categorized based on their connectivity and function.

Learn about association fibers: Association fibers are responsible for connecting different areas within the same cerebral hemisphere. They allow communication between regions of the brain on the same side.

Compare association fibers with commissures: Commissures are fiber tracts that connect corresponding areas of the two cerebral hemispheres, enabling interhemispheric communication. The corpus callosum is a major example of commissures.

Understand projection fibers: Projection fibers connect the cerebral cortex with lower brain regions and the spinal cord. They are involved in transmitting signals between the brain and the rest of the body.

Identify the correct answer based on the definition: Since the problem asks for fiber tracts that allow neurons within the same cerebral hemisphere to communicate, association fibers are the correct type of fiber tracts.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Association Fibers

Association fibers are bundles of axons that connect different regions within the same cerebral hemisphere. They facilitate communication between nearby cortical areas, allowing for the integration of information and coordination of functions. An example is the arcuate fasciculus, which connects Broca's and Wernicke's areas, crucial for language processing.

Commissures

Commissures are fiber tracts that connect corresponding areas of the two cerebral hemispheres, enabling interhemispheric communication. The most notable commissure is the corpus callosum, which allows for the transfer of information between the left and right sides of the brain, playing a vital role in coordinated brain function.

Projection Fibers

Projection fibers are long axons that connect the cerebral cortex with lower brain regions and the spinal cord. They are essential for transmitting motor commands from the brain to the body and sensory information from the body to the brain. An example includes the corticospinal tract, which is involved in voluntary motor control.
