What is the name of the tissue that connects the right and left hemispheres of the brain?

The tissue that connects the right and left hemispheres of the brain is known as the corpus callosum. This structure is a thick band of neural fibers that enables communication between the two hemispheres, allowing for the transfer of information and coordination of functions. The corpus callosum plays a crucial role in integrating sensory and cognitive processes from both sides of the brain, which is essential for the overall functioning of the cognitive processes such as perception, motor control, and language.

In contrast, other options refer to different brain structures with distinct functions. The cerebral cortex is the outer layer of the brain involved in higher-level functions like thought, perception, and decision-making but does not specifically connect the hemispheres. The thalamus acts as a relay station for sensory information, directing it to appropriate areas in the cortex but does not serve as a connector between hemispheres. The hippocampus is primarily associated with memory formation and spatial navigation and does not connect the hemispheres. Thus, the corpus callosum is uniquely positioned to facilitate interhemispheric communication, making it the correct answer.
