The Calculating Brain: New Studies Suggest That Neurons Are Built To Perform
Simple Arithmetic

The tiniest wires that link neurons to one another probably serve a critical
role in the brain's computational function.
New data about how these wires, or dendritic spines, modulate their electrical
properties and receive incoming signals is giving scientists a more complete
view of their knack for acting as efficient mathematical calculators.
Moreover, the findings also hint that these dendritic spines could make the
human brain a far more efficient learning machine than that of other animals.
