Brain exercise: Frontal and Parietal Lobes

September 20, 2006 by Alvaro Fernandez

Let’s now exer­cise our Frontal Lobes (that deal with work­ing atten­tion, among oth­er things), and Pari­etal Lobes (visu­al inter­pre­ta­tion). (Basic brain anato­my here)

Quick!, count the num­ber of times the num­ber “7” appears below. Then, count the total of both “1“s and “2“s, try­ing to add the total num­ber of both as you see either (this is, don’t just count all the “1“s, and then the “2“s)

    Well, first, con­grat­u­la­tions to every­one who has tried, since this type of exer­cise has been used by the mil­i­tary to improve attention.
