Inequality linked to differences in kids’ brain connections

Growing up in a socioeconomically disadvantaged household may have lasting effects on children’s brain development, a large new study suggests. Compared with children from more-advantaged homes and neighborhoods, children from families with fewer resources have different patterns of connections between their brain’s many regions and networks by the time they’re in upper grades of elementary school.
One socioeconomic factor stood out in the study as more important to brain development than others: the number of years of education a child’s parents have.

Silicon ‘neurons’ may add a new dimension to computer processors

When it fires, a neuron consumes significantly more energy than an equivalent computer operation. And yet, a network of coupled neurons can continuously learn, sense and perform complex tasks at energy levels that are currently unattainable for even state-of-the-art processors.What does a neuron do to save energy that a contemporary computer processing unit doesn’t?Computer modelling by researchers at Washington University in St.
