A neuron with a receptive field that overlaps with a figure fires action potentials at a higher rate than neurons with a receptive field on a background. The difference in firing rate is known as figure-ground modulation (FGM). FGM in early visual cortex is ...

While this logic seems solid, these protocols are actually very limited in their ability to isolate mirror neuron activity. The problem, as mentioned above, is that the vast majority of neurons active durin ...
