Table 1.

The proportion of total identified neurons within BL/BM, omPFC, ACB, and CEA, which project to the LHA (FG-labeled), that were labeled with IEG markers in response to food consumption tests

Region CS+ (%) CS- (%) CS+ and CS- (%) FG only (%)
BL/BM 19.8 ± 2.9 8.0 ± 2.2 40.2 ± 2.0 32.0 ± 4.4
omPFC 19.0 ± 1.7 7.3 ± 0.5 43.9 ± 3.2 29.8 ± 3.4
ACB 9.2 ± 2.6 8.2 ± 3.4 25.0 ± 4.0 57.6 ± 5.8
CEA 5.7 ± 2.2 13.3 ± 3.4 31.9 ± 3.7 49.1 ± 6.9
  • The first two columns show the percentage (mean ± SEM) of total projecting neurons in which IEG markers were induced selectively by the tests with CS+ presentations (CS+) or by the tests with CS- presentations (CS-). The third column shows the percentage (mean ± SEM) of total projecting neurons in which the IEG markers were induced nonselectively by both tests (CS+ and CS-). The fourth column shows the percentage (mean ± SEM) of total projecting neurons that did not contain the IEG markers.
