Final answer:
Neural networks, as they are responsible for the complex processing of multiple sensory information aspects in the brain, occurring in the multimodal integration areas of the cerebral cortex.
Step-by-step explanation:
People can process multiple aspects of sensory information such as color, shape, and size simultaneously because of the functioning of neural networks.
Neural networks in the brain perform complex processing by integrating information from different sensory modalities. This process occurs in multimodal integration areas of the cerebral cortex, where initial sensory processing moves on to associative and then integrative stages. These stages can involve memory, learning or cognition, all of which are higher-level cortical functions.
The cerebral cortex plays a fundamental role in orchestrating these processes, building on the inputs from various sensory receptors and sensory pathways. Once perceived, sensory stimuli are combined and further processed, which can lead to a response or the integration of these perceptions into memory. These inputs can trigger motor processing as well, usually in differing areas of the cortex.
