Recent findings in cognitive neuroscience are also beginning to unravel how the body perceives magnitudes through sensory-motor systems. Variations in size, speed, quantity and duration, are registered in the brain by electro-chemical changes in neurons. The neurons that respond to these different magnitudes share a common neural network. In a survey of this research, cognitive neuroscientists Domenica Bueti and Vincent Walsh tell us that the brain does not treat temporal perception, spatial perception and perceived quantity as different.2013 July 9, Joselle DiNunzio Kehoe, “Cognition, brains and Riemann”, in plus.maths.org, retrieved 08 Sep 2013:
