   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. 2013-07-09, Joselle DiNunzio Kehoe, “Cognition, brains and Riemann”, in plus.maths.org, retrieved 2013-09-08
