Document Summary
What areas of the brain are involved in mathematics in adults: embodied cognition, spatial maps. People with high math anxiety show activation in pain network even when anticipating having to do math. Numerosity = numeric properties of a set of objects. Monkeys reach for a jar with more treats after hearing the number of treats go into the jar. Neurons in the intra-parietal sulcus and lateral pfc respond specifically to numeric quantities in monkeys. Approximate number sense: engaged when number > about 4. Adults process spatial hand gestures and magnitude using similar regions in the posterior parietal lobe: children do not show overlap in these regions. Tms of angular gyrus also impairs finger representation and calculation. Small effects on subitizing, ordinality judgments and counting. Horizontal intraparietal sulcus (hips): representations of magnitude. Supplemented by: angular gyrus: verbal, mental antimetic (also involved in reading).
