Fig. 7.

Responses to electrical and mechanical stimuli at different depths in the pallium. Responses to electrical are superficial, in the caudal half of the Dm. Responses to mechanical stimuli are obtained in a similar area but always more ventrally, beginning ∼700 μm below the surface. Note that in this sample an electrosensory response resumes in an altered form at 800–900 μm. Single sweeps, vertical line marks stimulus onset.
