(Cell Press) Seventeenth-century mathematician Blaise Pascal first introduced the idea of expected value, which is reached by multiplying the value of something (how much it's wanted or needed) with the probability that we might be able to obtain it. Now some very 21st century research is showing for the first time in monkeys which parts of the brain are involved in the two-pronged decision-making process that determines this expected value. The study appears in Neuron.
