Final answer:
The conductive regions of the brain are located in white matter, which consists of myelinated nerve fibers and helps in the transmission of electrical signals. Gray matter, which covers the cerebral cortex, handles processing and brain functions, while the corpus callosum, also white matter, facilitates interhemispheric communication.
Step-by-step explanation:
The conductive regions of the brain are found in the white matter. This area contains myelinated nerve fibers, which are responsible for transmitting signals throughout the brain and to the rest of the body. By contrast, gray matter primarily consists of neuronal cell bodies and is involved in processing and regulating brain functions.
The myelin sheaths surrounding the nerve fibers in the white matter are essential for the efficient conduction of electrical impulses. The cerebral cortex, a layer of gray matter, covers the outer portion of the cerebrum and is involved in higher brain functions such as memory, attention, perception, cognition, awareness, thought, language, and consciousness.
Deep within the cerebrum, the corpus callosum which is composed of white matter, provides a pathway for communication between the two hemispheres of the brain.
