One hypothesis, called the Mental Synthesis Theory,says that, again, timing is key.If the neuronal ensembles for the dolphin and pineapple are activated at the same time,we can perceive the two separate objects as a single image.But something in your brain
has to coordinate that firing.One plausible candidate is the prefrontal cortex,which is involved in all complex cognitive functions.Prefrontal cortex neurons are connected to the posterior cortex by long, spindly cell extensions called neural fibers.
