Rats learn to discriminate artificial sensations generated using DCS. (a) Learning curve showing that rats learned to discriminate between two DCS patterns (Pattern 1:100 pulses and Pattern 2: 1 pulse). Graph shows percentage of correct trials as a function of session number (Red dots/green bars indicate mean ± s.e.m for 11 sessions in 12 rats, green line represents chance level of 50%). (b) Discrimination performance for each of the two patterns shown individually across sessions (mean ± s.e.m). (c) Learning curve showing rats that learned to discriminate three DCS patterns (Pattern 1: 100 pulses at 333 Hz, Pattern 2: 1 pulse and Pattern 3: 100 pulses at 100 Hz). Graph shows percentage correct trials (Red dots/green bars indicate mean ± s.e.m for 17 sessions in two rats, green line represents chance level of 33%). (d) Discrimination performance for each of the three patterns shown individually across sessions (mean ± s.e.m).
