Figure 2. Examples of Arc induction in basolateral amygdala and insular cortex.

Figure 2

(A, B) Schematic drawing of brain sections assayed at the level of (A) the basolateral amygdala, and (B) the insular cortex (adapted from Paxinos & Watson, 1998). Each red square represents the regions where image stacks were obtained. Ai: agranular zone of insular cortex; Ba: basal nucleus of amygdala; Ce: central nucleus of amygdala; Di: dysgranular zone of insular cortex; Gi: granular zone of insular cortex; La: lateral nucleus of amygdala. (C, D, E, F) Representative fluorescent images at the level of the basolateral amygdala (C, E) and insular cortex (D, F) using the Apotome microscope system (Zeiss). Green is the Sytox green nuclear staining and red is the Cy3 signal used to detect Arc mRNA. Images taken from the Caged control rats (C, D) and from the Paired animals exposed to odor and taste (E, F). The yellow lines delineate the basolateral amygdala and insular cortex. Scale bar, 1mm.
