| MSG | NaCl | |
|---|---|---|
| AM | ||
| Excitatory | 15 (38%) | 19 (30%) |
| Inhibitory | 6 (15%) | 6 (9%) |
| Complex | 0 (0%) | 2 (3%) |
| No response | 19 (48%)* | 37 (58%) |
| Total | 40 | 64 |
| LH | ||
| Excitatory | 10 (23%) | 10 (22%) |
| Inhibitory | 16 (36%)* | 13 (28%) |
| Complex | 0 (0%) | 0 (0%) |
| No response | 18 (41%)* | 23 (50%) |

Significant difference from the intact rats (residual analysis, standard residual > 2.0).
AM, amygdala; LH, lateral hypothalamus; Saline, physiological saline.
