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.

Autistic Adults Have Unreliable Neural Responses, Carnegie Mellon-Led Research Team Finds

Neuroscientists take the first step toward deciphering the connection between general brain function and emergent behavioral patterns in autism. Study shows that autistic adults have unreliable neural sensory responses to visual, auditory and somatosensory, or touch, stimuli.

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.

How Early Social Deprivation Impairs Long-Term Cognitive Function

A study shows social isolation during early life prevents the cells that make up the brain's white matter from maturing and producing the right amount of myelin, the fatty "insulation" on nerve fibers that helps them transmit long-distance messages within the brain.

Simple Mathematical Computations Underlie Brain Circuits

Neuroscientists report that two major classes of brain cells repress neural activity in specific mathematical ways: One type subtracts from overall activation, while the other divides it.
