Which of the following is true of the multimodal association cortex? It allows us to tie information that we receive to previous experience and knowledge, and helps us decide what action to take. It integrates sensory input to produce understanding of an object being felt. It regulates our heart and other involuntary muscles in response to environmental stimuli. It permits the perception of sound stimuli and stores them for future reference.
