fMRI studies to examine the brain regions of the visual association cortex, including V1, V2 or V4/V8. With “colored-hearing” synesthetes, the left V4/V8 regions were also activated by speech, in comparison to a control group who did not have such activation. From this information, the researchers found that “colored hearing” does exist and have gained more knowledge about the processes that work together to make additional imagery perceived. Another portion of the brain related to synesthesia is the

People can control what they perceive based on their biological limits and how willing they are to push themselves to get to know themselves better.
