Figure 1. — Experimental design. A, Sample histology showing placement of electrode tips of the 21 rats included in the analysis. AID, agranular insular cortex (dorsal); DI, dysgranular insular cortex; GI, granular insular cortex. Adapted from Piette et al. (2012). B, Stimulation protocol. Fluids were delivered through an IOC (session length: 30 min). Tastants (NA/SU/SA/QU) were presented randomly and interleaved with water delivery. The time between each fluid delivery was 10 s. C, Example LFP signals (left) and spike rastergram (right) across trials. In this and other figures, time stamp 0 denotes onset of fluid delivery.
