How can you check that a sorted unit is really one neuron?

Look for impossible intervals. One neuron cannot fire twice within its refractory period, about a millisecond or two, so a unit with many spikes closer than that is contaminated by another cell. Units are graded as single units or multi-unit activity, and drift of the brain against the shank, which moves every footprint, is corrected before sorting.
