ID# indicates each animal, and n indicates the fraction of striatal electrodes where a significant change in synaptic strength was observed. The minimum, maximum and mean synaptic strength, following tetanus, is reported as a percentage of baseline for each animal with two or more tetrodes or electrodes, otherwise a single result is presented under mean change. Notes on experimental protocol:

These animals had a stimulating electrode with a slightly larger tip separation (0.6 mm).

These animals were tested in the barbiturate anesthetized state first.

These animals were implanted with a microwire array.
