These scanning techniques have revealed which parts of the brain are associated with which functions. Functional magnetic resonance imaging (fMRI) or positron emission tomography (PET) monitor blood flow. Each neuron can make contact with thousands or even tens of thousands of others, via tiny structures called synapses.
