Table 1.

Action potential (AP) rate and amplitude measured as an average considering all spikes detected by each channel for the duration of the experiment (72 h) and as an average of the spike detected over 60 min belonging to three periods, time zones 1, 2 and 3 (TZ1, TZ2 and TZ3, respectively, which correspond to 1 h after the beginning of the recording, at the time of maximum rate, and after 72 h).
