The primary role of the cerebrum in processing sensory information is to interpret and analyze data received from the senses, facilitating perception, thought, and action. The cerebrum is divided into two hemispheres, each responsible for different sensory modalities and cognitive functions. It integrates sensory signals from various sources, allowing for complex processing and coordination of responses. Additionally, the cerebrum is involved in higher-level functions such as reasoning, memory, and voluntary movement, making it essential for conscious experience and interaction with the environment.
