What Number is Halfway Between 1 and 9? Is it 5 or 3?

A new information-theoretical model of human sensory perception and memory sheds light on some peculiarities of the nervous system. Ask adults from the industrialized world what number is halfway between 1 and 9, and most will say 5. But pose the same question to small children, or people living in some traditional societies, and they're likely to answer 3.

Blue Brain Project Accurately Predicts Connections Between Neurons

Proof of concept: Researchers identify principles to support brain simulation models. Blue Brain Project has identified key principles that determine synapse-scale connectivity by virtually reconstructing a cortical microcircuit and comparing it to a mammalian sample. These principles now make it possible to predict the locations of synapses in the neocortex.
