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

1. Step 1: Understand the types of fiber tracts in the brain. Fiber tracts are bundles of axons that connect different parts of the brain, allowing communication between neurons.
2. Step 2: Identify the function of association fibers. Association fibers connect different regions within the same cerebral hemisphere, enabling communication between neurons in that hemisphere.
3. Step 3: Recognize the role of commissural fibers (commissures). These fibers connect corresponding areas between the two cerebral hemispheres, allowing interhemispheric communication.
4. Step 4: Understand projection fibers. Projection fibers connect the cerebral cortex with lower parts of the brain and spinal cord, facilitating communication between the cortex and other parts of the nervous system.
5. Step 5: Based on these definitions, determine which fiber tract type allows communication within the same cerebral hemisphere by matching the description to the correct term.

Key Concepts

Association Fibers

Association fibers are bundles of axons that connect different regions within the same cerebral hemisphere, enabling communication between neurons in those areas. They facilitate integration of information locally without crossing to the opposite hemisphere.

Commissures

Commissures are fiber tracts that connect corresponding areas of the two cerebral hemispheres, allowing communication between the left and right sides of the brain. The corpus callosum is the largest and most well-known commissure.

Projection Fibers

Projection fibers link the cerebral cortex with lower brain regions and the spinal cord, transmitting signals between the brain and the rest of the body. They do not connect areas within the same hemisphere or between hemispheres.
