Summary:
At least a third of the communicating cells in a front part of the brain critical for reasoning and planning seem adept at keeping track of the number of things seen, report scientists funded by the National Institute of Mental Health. What's more, they even pick favorite quantities.

At least a third of the communicating cells in a front part of the brain critical for reasoning and planning seem adept at keeping track of the number of things seen, report scientists funded by the National Institute of Mental Health. What's more, they even pick favorite quantities. Activity of neurons in the prefrontal cortex of monkeys trained to judge the number of dots on a computer screen reflected changes in quantity -- peaking for a preferred number and then dropping off progressively as the discrepancy between numbers of dots increased, the researchers found. The study adds to mounting evidence showing how the prefrontal cortex categorizes information from the senses. Drs. Andreas Nieder, David Freeman and Earl Miller, Massachusetts Institute of Technology, report on their findings in the September 6 2002 Science.
