a neuron actually weights its “advisors” unequally. Electrical currents have magnitudes. Strong synapses produce large currents in the dendrite, and weak synapses produce small currents. The “strength” of a synapse quantifies the weight of its vote in the decision of a neuron. And it’s possible for a neuron to receive multiple synapses from another neuron, as if allowing it to cast multiple votes—a further kind of favoritism.
