2. Have you thought about also employing a measure of 'fear' or timidity to correlate with c-fos expression?
3. Do you think vmh is acting through the mpoa...? inwhich case one would expect that vmh lesions would not enhance mat behav if the mpoa is simultaneously lesioned.
4. I looked at our medial amygdala Fos results in maternally experienced, vs inexperienced animals (in Fleming & Korsmit,1996)and noticed that for some groups at least, inexperienced animals had higher numbers of c-fos cells in ,medial and in cortical amygdala than did the experienced animals. Other areas where we found elevated c-fos expression in experienced, over inexperienced animals (but only under some conditions) were the nucleus accmbens, the prefrontal cortex and the habenula. Did you look at any of these sites?
5. Further thoughts are forthcoming
