Because he’s a professional athlete, weighs about 250 lbs, and is much stronger than I will ever be, the chance of me tackling him all by myself is virtually zero. But, imagine the following: I grab Mack’s left foot and hold on for dear life, and, at the exact same time¸ your TA, Zoe, grabs his right foot, another TA, Anna, grabs is left foot, while your other TA, Susan, jumps on his back. We might (if we’re lucky and the wind blows just right) have a chance of stopping him. The four of us grabbing Mack, all at the exact same time illustrates which principle of synaptic communication?
