Data are from a total of 1,701 neurons recorded from 4 rats across 2 successive stages of learning, the learning (n = 843 neurons) and overtraining (n = 858 neurons) phases. Neurons were categorized into 8 types based on the shape of their waveforms and temporal firing patterns. Data in bold type indicate neurons used for subsequent analyses, and those included fast-spiking neurons with narrow waveform, burst-firing neurons with wide waveform, and regular-firing neurons with wide waveform.
