If you can’t remember where you left the car keys, take comfort in a new study that suggests the brain’s memory capacity may be far lower than once thought.
About 100 billion neurons, or brain cells, make up the average adult’s brain, but the computer-based discovery shows our memory isn’t based simply on neuron numbers. Instead, the limited amount of connections a neuron can make to other neurons may cut memory capacity.
“People have suspected this for a long time, but we’ve shown it’s possible for the first time in realistic memory networks,” said study co-author Peter Latham, a neuroscientist at University College London
